Build iOS & Android Frontend for Existing Platform

I am looking for an experienced mobile developer (React Native or Flutter) to build the iOS and Android applications for an existing, fully-featured web platform. The platform is a comprehensive app that connects users with local listings, a multi-vendor marketplace, job boards, and event bookings. You do not need to build any backend infrastructure. The backend is powered by Supabase, and we have 83 documented Edge Functions acting as a complete REST API. Everything from Stripe payments, auth, geocoding, and chat is already built and working on the web. Your job is purely frontend mobile development and API integration. Key Features to Implement (Mobile UI): Authentication: Email/Password & Profile setup (Supabase Auth). Discovery & Maps: Location-based search, filtering, and interactive map views for local listings. Marketplace: E-commerce product browsing, cart management, and Stripe Checkout integration. Events: Browsing and interacting with job postings and event schedules. User Dashboards: Order history, favorites, real-time chat messaging, and basic account settings. (Note: Complex admin tools and business owner dashboards will remain web-only for now to save scope). Tech Stack Requirements: Framework: React Native (Expo preferred) or Flutter. (React Native is a plus since our web app is built in React). Backend Integration: Supabase (Database, Storage, Auth) and REST APIs. State Management: Your preferred robust solution. What I Will Provide: 1. Full API documentation (Route map, endpoints, payload structures). 2. Access to the fully functioning web application for feature reference. 3. Design inspiration/guidelines for the mobile UI. Budget & Timeline: Budget: £5,000 - £6,000 (Fixed Price) Timeline: Please propose a realistic timeline in your bid. A milestone-based payment structure is preferred. To Apply, Please Include: 1. Links to 2-3 apps you have published on the App Store/Google Play. 2. Your preferred framework (React Native vs. Flutter) and why. 3. Confirmation that you are comfortable working with an existing Supabase REST API backend.

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.

Web design and development

am currently looking for a web developer to build a new website for my business. I already have the content, logos, brochure, and a clear brief for what I want. I also have examples of a few websites I like and can share these for reference. I do have the hosting login details, along with the GoDaddy access, so everything can be transferred and picked up smoothly. I am looking for a bold, high-quality website with around 6–8 pages, including a strong homepage and a professional overall look and feel. The current web design does not reflect the standard I want for the brand.
