Nine years inside teams.
A long detour through side projects.
AI agents as the missing piece.

I've been writing code commercially since 2017, almost always for foreign companies. Full-stack at secupay AG (DE) on a payment system processing ~175,000 transactions per day, then again at Shopmeister (DE) integrating Shopware 5 with Zalando, Tradebyte and other marketplaces. Frontend after that: Installation Made Easy® (Dawsonville GA, US enterprise SaaS for the home-improvement industry), Assertis (UK railway ticketing — Caledonian Sleeper among them), Maandag (NL two-sided staffing platform), and currently Shiji.

Five direct foreign employers, all on their own products. Three years at secupay on the payments platform, then steady senior+ roles in DE, UK, NL — currently Shiji.

Underneath all of that, I've been trying to ship my own products for years. Bogusz Pękalski's Od Developera do Foundera course and Discord community, the indie-hacker canon, many attempts. Most stalled around 60% complete: backend infra, DevOps, scope I underestimated, edge cases I couldn't crank through alone after an 8-hour day job.

Between Maandag and Shiji I took a few months to recover and look for the next role through what was probably the hardest tech hiring market in a decade. In that window I shipped company-docs-gpt— an early AI-assisted Q&A experiment over company documentation, months before agent workflows became the default working mode.

My exposure to AI didn't start with the LLM wave. In early 2016 I had a university AI semester — Python + TensorFlow (months after Google open-sourced it), image classifiers, flower and object recognition. Then years of frontend commercial work without much AI day-to-day. I picked up Cursor in 2023 — early enough that AI in the IDE was still mostly autocomplete + chat. What changed with the Sonnet 4 → Opus 4.5 generation of models: AI agents stopped being autocomplete and became real co-engineers. The 60% wall stopped existing — HiddenJobs.pl shipped end-to-end. Live, with real users, growing.

Currently focused on shipping HiddenJobs.pl and a v2 of Company Docs GPT. Long-term I want to do this inside a team — AI Product Engineer, founding-engineer, or Forward-Deployed roles at AI-native companies. Early-stage startups, scale-ups shipping AI features, or labs at the frontier. What matters: AI-native engineering as the default mode, not an experiment. IC craft + product judgment + shipped end-to-end proof is what I'd bring.
