Dedicated Linux Server Health Check, Upgrade Advice & Migration

Project Overview: I am looking for an experienced Linux server specialist to review the health and setup of our current dedicated server with Fasthosts and advise whether we should proceed with an upgrade and migration. We currently run 3 live websites on a dedicated Ubuntu 20.04 server via Plesk. The server has 32GB RAM. A recent backup failure flagged a RAM issue where the system removed the snapshot during the backup process. No further alerts have come through since, but it has raised concerns about overall capacity and stability. Fasthosts have recommended either optimisation or upgrading. Proposed Upgrade (from Fasthosts): • Server: E3-1270-64-HDD • RAM: 64GB • OS option: Ubuntu 24.04 with Plesk What I Need From You: Phase 1 – Server Health Check & Review • Review current server setup (Ubuntu 20.04, Plesk Obsidian) • Check RAM usage, CPU, disk, services, and general performance • Review backup configuration and failure cause • Identify any inefficiencies or risks • Confirm whether upgrade is genuinely required or if optimisation would suffice Phase 2 – Upgrade Recommendation • Provide a clear recommendation: Stay and optimise OR Upgrade and migrate • If upgrading, confirm whether the proposed Fasthosts server is suitable Important Constraint: We must remain on PHP 8.2.30. No PHP upgrades to be carried out as part of this work due to compatibility with existing code. Phase 3 – Migration (if approved) • Full migration of 3 websites to new server • Maintain Plesk structure and configurations • Ensure: Minimal downtime All services tested post-migration Backups working correctly Key Requirements: • Strong experience with: Linux (Ubuntu) Plesk Fasthosts / similar environments Server migrations Backup systems (Acronis or similar) • Must work carefully with live production sites • Clear communication and sensible approach Pricing: I require a fixed price for: 1. Health check and recommendation 2. Migration if needed Additional Notes: • Current issue appears linked to RAM during backups, but system otherwise looks stable • Storage is nearing capacity on backup system

Deploy Python AI Automation System on Linux Server

Deploy Python AI Automation System on Linux Server (Social + Multilingual Sub‑sites) Duration 3–4 working days Skills needed Python, Linux/Ubuntu, Nginx, MySQL, REST APIs, Social Media APIs (Meta Graph, X, Pinterest), S3‑compatible storage About the project We run Librifly.com, a platform selling downloadable art, images, stories, poetry and maps, also available as posters, notebooks and books. We already have a complete AI automation system built: all Python code is written, tested and documented. This is not a coding project. You will deploy and configure the existing code on our Linux server and verify that the full system works end‑to‑end. Think of it as a technical installation and setup job: server environment, Nginx, database migrations, social media API configuration and final testing. What the system does • Discovers content niches from Librifly.com (e.g. Monet, Vintage France travel, New York art). • Generates complete sub‑sites for each niche using AI (e.g. monet.librifly.com). • Populates each sub‑site with real products and pricing from Librifly.com. • Publishes each sub‑site in 9 languages, one new language per day. • Automatically posts to Instagram, Facebook, X (Twitter) and Pinterest when each site goes live. Server environment • Hetzner Cloud server (Finland), Ubuntu + Nginx. • MySQL database already running. • Static IP and domain configured. • Python 3.12 and Redis to be installed (apt install). Scope of work Step 1 — Server setup • Install Python 3.12 and Redis, create a virtualenv. • Install Python packages from requirements.txt. • Configure .env with our API keys. • Run 4 SQL migration files. • Set up Nginx wildcard subdomain (*.librifly.com). • Obtain wildcard SSL via Let’s Encrypt certbot. • Configure two systemd services (Celery worker and scheduler) to start on boot. Step 2 — Pipeline test • Run the pipeline manually and verify a sub‑site is generated. • Check HTML renders correctly in a browser. • Verify Nginx serves it on the correct subdomain. • Adjust scraper selectors if needed by inspecting Librifly.com. Step 3 — Social media setup • Create a Meta developer app (Instagram + Facebook). • Configure long‑lived access tokens for posting. • Set up X (Twitter) and Pinterest developer apps. • Configure a Hetzner Object Storage bucket (S3‑compatible). • Send at least one successful test post on each of the four platforms. Step 4 — Multilingual test • Run migration for language tables. • Build and test a Spanish version of one sub‑site. • Confirm hreflang SEO tags in HTML. • Check CJK (Chinese/Japanese/Korean) pages load with correct fonts. Required skills • Python 3 (read/debug existing code). • Linux Ubuntu server admin. • Nginx (vhosts, wildcard subdomains). • SSL with Let’s Encrypt / Certbot. • MySQL (running SQL files, basic admin). • Social media APIs, especially Meta Graph API. • REST API basics (X and Pinterest). • S3‑compatible storage (e.g. Hetzner Object Storage). What we provide • Full source code (4 documented zip files). • README files with step‑by‑step instructions. • SSH access to our server (securely shared). • All required API keys. Deliverables 1. At least one sub‑site live at a .librifly.com subdomain. 2. Celery worker and scheduler running as system services and surviving restarts. 3. One successful test post on Instagram, Facebook, X and Pinterest. 4. Brief handover note covering token expiry dates and how to run the pipeline manually. Meta setup note Meta (Instagram/Facebook) app setup is the most time‑consuming part because the portal is slow and the flow is non‑obvious. Please only apply if you have previously set up a Meta Graph API app; if not, say so clearly in your proposal. How to apply Please include: 1. Whether you have set up a Meta Graph API app before (Instagram/Facebook posting). 2. Whether you have configured Nginx wildcard subdomains and Let’s Encrypt wildcard SSL. 3. When you can start and hours per day you can commit this week. 4. Your fixed‑price quote for the full project.

Fix Magento 2 Product Card Layout

Mirasvit Rewards Points Injection Causing Star Rating Overlap We need an experienced Magento 2 frontend developer to fix a product card layout issue on our store. The Problem We use the Mirasvit Rewards module. On page load the product cards display correctly -- star ratings appear in the right position. After the Mirasvit "Earn X VIP Points" block injects via JavaScript into the price area, the card layout breaks and star ratings overlap the Add to Cart button. This affects the homepage product grid on desktop. Mobile and category pages must not be touched. What We Know The Mirasvit points block injects via the catalog_product_prices layout handle into the render.product.prices block on every price render. The injection adds height to the price area dynamically after page load. The card uses a custom flex layout defined in list.phtml and config.phtml. Something in the card is absolutely positioned and does not reflow after the injection. The fix must be scoped to the homepage desktop grid only using .cms-index-index or .no-breadcrumbs selectors. No changes to mobile breakpoints or category page rules. Stack Magento 2.4.3-p3, PHP 7.4, custom theme, Plesk/Ubuntu server. SSH access will be provided. Requirements Proven Magento 2 frontend experience. Familiarity with Mirasvit Rewards module is a strong plus. Must be able to diagnose via Chrome DevTools and apply a surgical CSS fix. Fixed price, clearly scoped deliverable.

Trading bot development

Project Overview We are building a high-performance, low-latency trading engine designed for microstructure-based execution strategies in a high-tax (STT) environment. This is NOT a basic retail trading bot. This system requires advanced system-level engineering, multi-core CPU architecture control, shared memory communication, and real-time observability dashboard. The focus of this project is minimizing latency between signal generation and order execution while maintaining regulatory compliance (Order-to-Trade Ratio constraints). The developer must understand low-level performance optimization, concurrency architecture, and Linux system behavior. Core Technical Requirements Python Version (Mandatory) The engine must use: Python 3.13 Free-Threaded build (3.13t) NOT standard Python 3.10–3.12 Reason: Standard Python uses the Global Interpreter Lock (GIL), which blocks true parallelism. In low-latency systems, a 1–2ms delay caused by GIL contention is unacceptable. Multi-Core Architecture with CPU Core Pinning The engine must: Assign specific modules to specific CPU cores Use os.sched_setaffinity (Linux only) Prevent OS core migration (avoid context switching) Modules include: Sentinel (Risk & OTR monitoring) Sonar (Market entropy / regime detection) Oracle (Signal calculation loop) Execution Engine (Order placement) The goal is to eliminate unpredictable latency spikes caused by OS scheduling and cache invalidation. Inter-Process Communication Standard Python queues are NOT acceptable. Communication must use: multiprocessing.shared_memory Memory-mapped buffers Lock-free ring buffer architecture Reason: Standard queues introduce locking and object allocation overhead, increasing latency. The target is sub-millisecond internal communication between signal generator and execution engine. Latency Measurement The system must measure: End-to-end order placement latency Round-trip time (RTT) Module processing time Using: time.perf_counter_ns() Latency histogram logging This data must be streamed to the dashboard. Order Execution Logic The system should: Prefer passive limit orders Include 200ms cancel logic Manage Order-to-Trade Ratio (OTR) Implement controlled order flooding logic (compliant with broker rules) This is not a simple market order bot. FRONTEND REQUIREMENTS (React Dashboard) The frontend is NOT a trading UI. It is a real-time monitoring and control cockpit. Preferred stack: React (Vite or Next.js) WebSocket for live streaming Lightweight charting (Canvas or WebGL-based) Required Dashboard Modules Sentinel Panel Real-time RTT graph 20ms lockdown threshold indicator CPU usage per pinned core Emergency status Sonar Panel Market regime indicator (Attack / Veto mode) Entropy score display Zero-trust gate status Oracle Panel Weighted Order Book Imbalance (WOBI) heatmap Liquidity imbalance % Signal strength score Must use high-performance rendering (Canvas, not heavy SVG). Execution Panel Net Expected Value (NEV) Fill rate % Cancel rate Order-to-Trade Ratio (OTR) status Emergency Kill Switch Dashboard must include: Global kill switch Sends signal to monitoring service Monitoring service writes flag to shared memory Engine halts immediately Dashboard must NOT communicate directly with broker API. Deployment Requirements Linux-based environment (Ubuntu preferred) Dockerized setup preferred Separate processes: Trading engine Monitoring microservice React frontend Google Cloud compatible. 10 MOST IMPORTANT SKILLS TO ADD Attach these skills on Freelancer: Python 3 (Advanced Concurrency & Multiprocessing) Must understand GIL, free-threaded builds, shared memory. Low-Latency System Design Experience reducing microsecond-level bottlenecks. Linux System Programming Knowledge of CPU affinity, process scheduling, performance tuning. Multithreading & Multiprocessing Architecture Designing multi-core optimized applications. Memory Management & Shared Memory IPC Experience with mmap, shared memory buffers. Financial Market Microstructure Knowledge Understanding order books, liquidity imbalance, passive vs aggressive orders. WebSocket & Real-Time Streaming Required for live dashboard data. React.js (Performance-Optimized UI) Real-time data rendering without UI lag. Performance Profiling & Benchmarking Must measure and optimize latency. Cloud Deployment (Google Cloud / Linux VM / Docker) Production-ready deployment experience. VERY IMPORTANT Add this to filter weak developers: Applicants must answer the following: Have you worked with Python shared memory or mmap before? Have you implemented CPU core pinning on Linux? How would you measure internal engine latency? How would you prevent dashboard from affecting trading engine performance? This will eliminate 80% of generic bot developers.

Linux incident response / sysadmin

Hi, I’m looking for an experienced Linux incident response / sysadmin to help with a server issue. A Linux server previously had an xmrig miner infection. Most artefacts have been removed, but something on the system is still intermittently attempting to download a miner script via wget.

Senior Backend / Automation Control Plane Engineer (Java/Spring)

We’re building an Automation Control Plane that runs large-scale, cross-platform activity across multiple channels – tens of thousands of identities executing coordinated, daily actions from both Android emulators and headless browsers. The core backend already exists in Java/Spring Boot; your job is to turn it into a clean, scalable “one brain, many workers” platform and get it running in production fast. Today, we have a substantial Spring Boot application that knows about devices, sessions, users, and execution requests, plus a full suite of workflows (for one platform) automated via Appium. That code was originally written to drive physical Android phones in a device farm. We’re now moving to Android emulators on Ubuntu servers and need to stabilize and finish the existing backend so those flows run reliably on a VM-based farm. Your primary responsibility is to own this backend as the control plane. You’ll extend the current models (ExecutionRequest/History, Session, Device, etc.) to support multiple worker types, introduce a clean WorkerType/ApplicationType/TaskType model, and design simple job APIs so different worker pools can pull work and report results. In practice, that means adding a generic job/worker abstraction on top of what’s already there, not rewriting from scratch: the Spring app remains the single orchestrator, and emulator and headless services become pluggable executors behind it. From there, you’ll implement and integrate the first headless worker service – likely using Playwright or a similar framework. This worker will fetch jobs from the control plane, run automated interaction and content workflows (e.g. posting, engagement, scripted journeys) for specific accounts, and push results back into the same execution history the emulator jobs use. You’ll also help wire in the initial CRM/funnel logic so multi-step outreach sequences can be expressed as data and emitted as jobs to the right worker type, respecting per-account limits and anti-detection constraints. In parallel, you’ll help design the foundations of an AI-driven video pipeline that turns long-form source material into high-volume short-form assets. You won’t be training models from scratch, but you will be responsible for integrating with external AI services (for script generation, voiceover text, captioning, clip selection, etc.), defining the data contracts, and wiring the output back into the control plane as structured jobs. The goal is to treat “generate clips + copy + metadata for distribution” as just another worker pipeline the orchestrator can schedule, monitor, and feed into the posting and engagement workflows. We’re looking for someone who is very strong in Java and Spring Boot, comfortable taking over and refactoring an existing backend, and experienced with distributed job/worker systems (job tables, status, retries, idempotency, simple REST or queue-based dispatch). You should be fluent with relational databases, REST API design, and running services on Linux (Ubuntu), and at least conversant with containerization (Docker, Kubernetes or similar). Hands-on familiarity with UI automation tools (Appium, Selenium, Playwright, Puppeteer, etc.) is important: you don’t have to be a career QA engineer, but you should understand the realities of flakiness, selectors, waits, and running many parallel sessions. It’s a big plus if you’ve worked on high-scale marketing or growth automation, anti-detection/device farms, or CRM/funnel engines that coordinate multi-touch sequences over time. This role suits someone who enjoys taking a messy but valuable codebase, truly understanding it, and turning it into a coherent platform with clear contracts and extensible architecture. You’ll be expected to think in terms of control planes, worker pools, and future expansion (new platforms, new worker types) while still delivering quickly on immediate milestones. If owning the brain of a real-world, high-volume automation platform sounds exciting, and you’re confident in your ability to drive a Java/Spring control plane from “partially built” to “running real campaigns,” we’d like to talk. Send a brief overview of your most relevant backend/platform work (especially job/worker systems or automation platforms), links to repos or case studies if you have them, and a short note on how you’d approach the first 4–6 weeks in this role.

Reliable DevOps Engineer Needed

I’m looking for an experienced DevOps / Backend Engineer to set up and configure a self-hosted Supabase instance on my Ubuntu VPS. Docker is already installed, but it should be verified and properly configured. The goal is a secure, production-ready Supabase stack running locally (Postgres, Auth, REST, Realtime, Storage, Kong Gateway, and optional Studio), behind an HTTPS reverse proxy with automatic backups and full documentation. Scope of Work Docker & Environment Setup Verify existing Docker installation (version, permissions, network stability). Create dedicated Docker network (supabase_net). Prepare directory structure under /opt/supabase/. Supabase Stack Installation Deploy Supabase components using Docker Compose: Postgres GoTrue (Auth) PostgREST (REST API) Realtime Storage API Kong Gateway (Optional) Supabase Studio Configure .env and docker-compose.yml following best practices: No public database ports. All services communicate over internal Docker network. Security & Networking Set up Nginx reverse proxy for HTTPS with Let’s Encrypt certificates. Configure UFW firewall (only ports 22, 80, 443 open). Add security headers and enforce HTTPS redirects. Keep all credentials and secrets outside version control. Backups & Monitoring Implement automated daily PostgreSQL backups (with 30-day retention). Include a tested restore script. Add basic monitoring and health checks (Docker health, HTTP status). (Optional) S3-compatible offsite backup upload. Testing & Validation Verify user sign-up, login, and password reset via GoTrue (SMTP). Confirm REST endpoints respond via HTTPS. Validate Storage uploads/downloads. Test Realtime subscriptions. Run at least 3 negative RLS access tests. Documentation Provide a short runbook (README) including: Install, deploy, and rollback steps. Backup and restore instructions. Secrets handling. Service management commands. Include .env.example with comments. Deliverables Fully running self-hosted Supabase stack on Ubuntu VPS. docker-compose.yml, .env.example, and Nginx config files. Verified TLS certificate (Let’s Encrypt) and working HTTPS. Working Auth, REST, Storage, and Realtime endpoints. Automated daily database backup + successful restore test. Clean and concise documentation/runbook. Technical Environment Ubuntu 22.04 LTS Docker & Docker Compose v2 Nginx with Let’s Encrypt Domain & DNS already configured SSH access available Acceptance Criteria HTTPS active, A-grade SSL config, forced redirect HTTP→HTTPS PostgreSQL not publicly accessible Auth, REST, Storage, and Realtime endpoints all operational Backups run daily; restore script verified Logs rotate properly, disk usage monitored Only ports 22/80/443 open (UFW enabled) Documentation and .env.example delivered No hardcoded secrets in any file under version control Timeline & Deliverables Estimated workload: 1–2 working days setup, +1 day for testing and documentation. Deliverables pushed via Git repository and deployed on my VPS. Required Skills Docker & Docker Compose (production environments) Supabase or similar stacks (Postgres, GoTrue, Kong, Realtime) Linux server administration (Ubuntu) Nginx + Let’s Encrypt TLS setup Bash scripting (for backup/restore) PostgreSQL and basic SQL/RLS understanding Additional Notes Docker is already running but needs verification. Domain and DNS are fully configured. No Supabase cloud integration — this must be 100% self-hosted. Open to small improvements if you can make the setup more robust or secure. ⚠️ Reliability Disclaimer Only apply if you agree to the fixed budget and milestone structure. Any attempt to renegotiate price or terms after acceptance will be reported to PeoplePerHour as a reliability issue. Serious professionals only, let’s keep things efficient and transparent.
