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.

From Hamm tun to Northampton.

I am looking for a comic book artist to draw my short horror series. Before I go into details here’s a few things for you to know before you send in an application for the role: - No A.I. Seriously, NO A.I! Do not even bother applying or wasting my time, you are not an artist, you are lazy. I will want to see drawings and sketches to show to you are not using A.I, and if you have been then you will be fired. I want a comic artist, someone who knows about comic pages and drawings, and if you have any prior experience on projects great, if not that’s ok as well. You will be drawing some dark themes and images, not awful or too extreme (Such as child mur-der or over the top gore). There will be some sex scenes or sexual acts and some violence but nothing over the top or super-super gore. This is not 100% required but I wouldn’t mind someone from England, as the comic takes place in England and we need to capture the grittiness of England and it’s people. My spelling and grammar can be awful sometimes, but reset assured I have hired an editor and someone who has spelled checked and grammar corrected my work, so the dialogue is correct and edited. Details of the project. I have been working on 6 short stories focusing on the occult within Northampton. If you like Alan Moore or the early John Constantine Hellblazer's you’ll hopefully like this. This story focus on magick (Yes, Magick with a K), taking inspiration from occultist like (Mainly) Aleister Crowley, John Dee and the gothic work of H.P Lovecraft. If you like the occult and magick, great! The story, for a brief summery, is about different people in Northampton and is a kind of pulp- fiction like story, where some events and characters cross over or impact others. I want to contain the details of the story due to not wanting to give too much away unless you are my artist. You will have to sign a contract saying you will not share or copy my work, even if you aren’t my artist and have made it through to the next stage. Just because this project is important to me and I have worked really hard on it for a few months and I don’t want someone to copy it or steal my ideas. All of the stories will be in black and white with only blood for colour, and the styles are usually simple realistic drawings - Think Hellblazer, swamp thing, Mr.A that kind of stuff (I’ll link some pages below). But there will be some different styles, such as how pages are laid out or maybe a different tone. One story is a cinema story, so there will be pages where it looks like the comic is a film tape burning or with film flickers. But you will have all this covered in a guide book. Now this book will detail everything, character designs, locations, styles, covers. Everything. Then on each comic layout you will have extra details relating to that issue. You will also have details on each page, such as how the page will look and what we see. A lot of the details for this project will be in the guidebook, so if you are chosen, or make it to the next stages of wanting to be my artist, I will send you the guide book and that will give you a better idea of what I want from you and what will be seen in this project. The goal of this project is to be my start in comics. I will be putting this online, on globalcomix and will also be submitting it to be published. This is the start of a long series involving Northampton and the occult, so you never know, if this goes well we might be working a lot more together and publishing our work in hopefully big companies. My goal is to submit this to Image comics, Dark horse or other major companies who are mainly independent. No Marvel or DC, not after what they did to Alan Moore and how Stan Lee took the credit for most of Marvel. As I work full-time I will be paying you per page when we are both free. I’m not expecting this to be done in a weeks time. I might pay you in one go depending on the price, but I will be looking to do a kickstarter and go fund me to help out. I can pay you, but it might not be in one go or maybe a few pages per month. One thing I will mention is you do have creative freedom, I will allow you to make suggestions or some ideas on maybe different angles or pages. I am very open and approachable. If you wish to apply please go ahead and we can discuss this further. If you have any proof of your work please submit that as well so I can have a look at your work. Again, NO A.I! Thank you for reading. (When you submit please state your per page cost, or maybe bundle deals, examples of work, a bit about you, and if you want to (Optional) your favourite comic character, series or anyone important in comics you like. In no real order, write however you like)

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.
