- [Work](https://piotrgospodarczyk.com/work.md): Six builds in full: Slipway, Tallywise, Handee, tendr, EVERYANGLE, and Future In Perspective. Problem, constraints, what I built, what it measured out at, what I handed over.
- [Method](https://piotrgospodarczyk.com/method.md): How I build: agent-first delivery on a harness I engineered, and the guardrails that make it safe to do inside somebody else's repository.

- [Tallywise case study](https://piotrgospodarczyk.com/work/tallywise.md): Company accounting and tax, a domain I had never worked in, sole-authored: an AI model reads the paperwork, plain code does the sums, and the first returns filed from its figures were acknowledged two days after the first commit.

- [EVERYANGLE case study](https://piotrgospodarczyk.com/work/everyangle.md): Six years as founding CTO of a computer-vision retail-analytics SaaS: EUR 3M+ seed round, EUR 1M+ ARR, 10+ engineers across six countries.
- [Future In Perspective case study](https://piotrgospodarczyk.com/work/future-in-perspective.md): A four-week contract in EU-funded education: security hardening across a WordPress estate of around eighty sites, then the tooling to run it.

## Optional

- [Also built](https://piotrgospodarczyk.com/work/also-built.md): Ten production systems from the EVERYANGLE years, listed for completeness and deliberately without figures of any kind.
