I build real-time Python market-data systems for trading desks.
SerbiaWhat I'm looking for
I build production market-data and trading systems for international clients as an independent Python developer. My real-time alert platforms stream US equity ticks, newswire stories, and regulatory filings, evaluate user-defined rules, and deliver desktop, audio, email, and scheduled reporting outputs.
I've built multi-process pipelines using Polygon.io, WebSockets, PostgreSQL, MySQL, Qt, and Excel-based workflows, often as the sole engineer working directly with clients. I focus on resilient long-running systems, including watchdogs, crash-safe resume, rate limiting, regression testing, and reliable delivery for non-technical users.
