Marc G.

Python engineer specializing in trading automation, data pipelines, and ML for financial markets. I build production-grade systems not weekend scripts, with proper error handling, configuration management, and clean architecture. 🔹 TRADING APIS — Interactive Brokers (TWS API), Alpaca, ccxt; risk-gated execution, portfolio tracking, real-time market data. 🔹 WEB SCRAPING — Selenium (stealth), BeautifulSoup, Scrapy; anti-detection, proxy rotation, adaptive rate limiting at scale. 🔹 ML / NLP — TF-IDF, XGBoost, transformer models (FinBERT); sentiment analysis, ticker extraction, ensemble model pipelines. Every project I deliver includes: ✅ Clean, typed Python with docstrings ✅ Config-driven design (YAML, no hardcoded values) ✅ Logging + audit trails ✅ Tested architecture, not "happy path" scripts ✅ Full source on GitHub I work best on projects where reliability matters more than quick-and-dirty MVPs. If your system needs to run unattended, handle errors gracefully, and produce auditable output I'm your person.
