- Engineering decisions (ADRs) - why Flutter, FastAPI, PostgreSQL and the rest. The why, not just the what.
- Engineering journal - build-in-public notes: lessons, mistakes, numbers.
- Benchmarks - real measured performance data, starting with this site itself.
- Architecture gallery - the reference diagrams behind our production systems.
