AI Product Engineer · Wrocław, remote · open to senior product & founding-team roles
Two live products. One engineer with Claude Code and Codex in the loop.
Nine years shipping for teams in Germany, the Netherlands, the UK and the US. Now I build and run my own products end to end: agents take the volume, I own the architecture, the product calls and what reaches production.

The employer side: foreign companies hiring Polish specialists remotely.
How a feature ships
Agents write most of the code. The process around them decides whether it is any good: specs, written standards, tests, review, and my own sign-off on every pull request.
- 01
Spec
Written with a planning agent: the product model, hard constraints, a numbered test list and a finish block.
- 02
Agents build to my standards
Claude Code or Codex CLI in their own git worktrees, held to written rules: SOLID, DRY, KISS, small pure functions, deny rules on anything irreversible.
- 03
Tests and gates
Unit tests on rules and edge cases, integration tests on data paths, Playwright E2E on user flows, lint on staged files, evals for AI features.
- 04
Agent review
A second agent in a fresh session reviews the diff against the spec and the standards, so I start my review from the findings.
- 05
I review and merge
Human in the loop: I read every pull request myself, run what changed, and merge only when I am sure. Then I watch production.
Agent code is held to written standards: SOLID, DRY, KISS, small pure functions, and tests that catch regressions. See the standards →
From the team I shipped with
Three recommendations from my team at Maandag in the Netherlands: the product owner I reported to, our business analyst and a fellow developer. Quoted word for word from LinkedIn.
Piotr worked as Front-end developer in my team at Maandag. I enjoyed working with him and he was an important part of the team, helping to realize our digital ambitions. He works well with other team members, takes responsibility and has a focus on quality. I would recommend to hire him for your team.Joost Verbiesen
Product Owner · my manager, Maandag
LinkedIn · Oct 2023 ↗Having Piotr in your team, is making sure that work is delivered of top notch quality. He doesn't shy away from questions or confrontations, which makes it very pleasant to work with him, as he is able to challenge others. Piotr is very eager to learn and improve himself and cares about your product. I would definitely like to work together with Piotr again.Sherilyn Pang
Business Analyst · Maandag

He has a professional work ethic, a commitment towards his work and craft, is cohesive within a team, is always willing to lend a helping hand, and always a pleasure and inspiration to have a brainstorming session, consultation and discussion. I would highly recommend Piotr!Craig Spindler
