Colin H.

Senior Python Developer | Trading Bots, API Integrations, AI, Crypto

I’m a Python/Django developer and algorithmic trading specialist who helps individuals and businesses design, build, and scale automated trading systems and market-driven applications. Unlike developers who only write code, I actively work with trading systems and real-world market data. That means I understand execution timing, edge cases, API limitations, risk management, and reliability - the things that actually make or break automated trading software. Whether you’re building a bot from scratch, improving an existing strategy, or connecting complex APIs into a reliable system, I focus on clean architecture, maintainability, and production-ready results. ✅ What I Help Clients Build - Custom algorithmic trading bots (stocks, options, crypto) - Backtesting and strategy validation frameworks - Broker and exchange API integrations - Trade execution, position management, and safety checks - Monitoring dashboards and admin panels (Django-based) - Data ingestion, automation, and analytics pipelines I’m comfortable working on greenfield projects or stepping into existing codebases to stabilize, refactor, and improve performance. 🔌 Platforms & Integrations Experience - Tradier - Interactive Brokers - TradeStation - E*TRADE - Binance - CryptoHopper - 3Commas If your platform has an API, I can work with it - or help you design a clean abstraction layer so you’re not locked into one provider. 🧩 Tech Stack Backend: Python, Django, FastAPI Frontend: React, HTMX, JavaScript, HTML, CSS Data & Automation: Pandas, NumPy, REST APIs Databases: PostgreSQL, MySQL Infrastructure: Azure, AWS, Docker 🔹 How I Work - Clear communication and realistic timelines - Production-first mindset (not throwaway scripts) - Secure handling of credentials and API keys - Documentation so you’re not dependent on me forever If you’re looking for a developer who understands both software engineering and trading mechanics, send me a message. I’m happy to review your idea, strategy, or existing system and suggest the best path forward.
