Ai Engineer · Python · Quant Research

I build Python and AI systems that have to be right before anyone relies on them.

Since October 2026 I have been a contract Software Engineer, AI Coding Tasks at Askable (Terminal-Bench 4), designing containerised coding tasks for AI coding agents with deterministic, offline test harnesses. As co-founder and CTO of Clashpoint.me (co-built with a CEO co-founder, not launched yet) I own most of the engineering on Python, FastAPI, PostgreSQL, Redis, CI/CD and AWS. At Airbus Defence and Space (since 2023) I analyse production data and built an internal release tool my team uses daily.

On the quant side I built a research platform with licensed equities and futures market data, strict validation (sealed holdout, FDR, deflated Sharpe, cost model) and agent-based build and verification. I also built QuantBrief, a five-agent LLM app (13.5K LOC in a weekend at the Mistral AI hackathon).

Looking for: fully remote roles as an AI / LLM engineer, Python backend or data engineer, or quant developer / researcher, full-time or contract. Based in Warsaw (CET), EU citizen.
