I build production ML systems and scalable backend infrastructure — from model training and institutional backtesting to real-time inference, monitoring and CI/CD.
Specializing in institutional-grade backtesting (CPCV, DSR, PBO) for quantitative trading platforms, high-performance Python backends, multi-agent LLM systems, and AI engineering — from RAG pipelines to autonomous agent architectures. Engineering discipline from aerospace applied to software.
BEng in Mechanical Engineering from Silesian University of Technology, currently pursuing a Master's in Project Management at Collegium Civitas while working full-time at Airbus Defence and Space. Alongside work and studies, completed 42 Warsaw — a tuition-free, peer-to-peer programming academy with no lectures or teachers, focused on project-based learning 24/7.
