03 / about
Specializing in validation methodology for quantitative research (CPCV, DSR, PBO, pre-registration), 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 and a Master's programme in Project & Process Management at Collegium Civitas (2024–2026), alongside full-time work 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.

- completedWorldclass Research Org — An Executable-Gate Multi-Agent Research OrganizationA multi-agent research organization (39 role files) where every output must pass executable gates and adversarial review. After a pre-registered calibration study it selected its own research program (C1, paused at pre-registration) and gained an adversarial pre-review org (System B).multi-agentai-agentsresearch-automation
- archivedX_Quant — A Quant Research Program That Learned to Say NoMy solo quant research program, in two lives. v1 (≈274K LOC) was retired in August 2026 and its published metrics are withdrawn. v2 rebuilt the process around a written research constitution and an append-only decision register. No strategy it tested was validated for trading.pythonquantitative-researchresearch-integrity
- in progressAlpha Lab — A Local Research Workstation for Honest Alpha ResearchA local research workstation for building algorithmic strategies and searching for alpha signals, with honesty built in: point-in-time data, a hash-chained trial ledger, sealed holdouts and overfitting statistics. Phases F0–F3 are done; there are no real-return results yet.pythonquantitative-researchbacktesting
- in progressUKenergy — Finding Sites for Battery Storage Across Great BritainA geospatial prospecting tool for battery-storage (BESS) projects in Great Britain, built on open data: 807,954 land parcels scored by distance to the grid, 2,625 BESS projects with their connection-queue status, and a learned site-ranking candidate tested on temporal and spatial hold-outs.pythongeospatialenergy
- pausedjob-agent — A Job Search Run by Agents, Under Rules I SetA system that finds fully remote roles across ~33,000 company job boards, reviews each with two independent AI opinions, writes a tailored, claim-checked CV and cover letter, and fills the application in a real browser. Captchas and judgement calls stay with me.pythonai-agentsclaude
- completedQuantBrief — AI-Powered Real-Time Market Intelligence AgentMulti-agent financial intelligence platform built at Mistral AI Hackathon — 5-agent pipeline screening 30+ articles in <50ms each, analyzing full SEC filings in 256K context, and delivering multilingual audio briefings.pythonmistral-aifastapi
- pausedESG Compliance Agent — AI-Powered Regulatory AssessmentEnterprise ESG compliance system with local LLM, FAISS vector search, and automated ESRS gap analysis across 10 regulatory modules.pythonllmrag
- pausedAirbus Document Analyzer — Air-Gapped AI SystemFully offline document analysis application with local LLM, OCR, and semantic search for high-confidentiality environments at Airbus Defence and Space.pythonllmrag
