How I Work
Four Principles I Will Not Compromise On
Type-safe by Default
TypeScript end to end. Strict mode on. Schemas at the edges. The compiler catches what tests will not.
Ship in Iterations
Two-week blocks, Friday demos, code in a real branch. No three-month silent sprints ending in surprise.
Document the Why
Code says what. Comments and ADRs say why. Your team six months from now thanks me for this.
Own the Full Stack
Frontend, backend, infrastructure, monitoring. No throwing problems over the wall to someone else's team.
On the Internet
My code lives at github.com/HolyMarcell - I've used this handle since 2010. The work and the name are the same person. If you found a Stack Overflow answer, an Elixir library, or a CSS Houdini paint worklet under that name, that was me.
Next Step
Let's work together. Schedule a 30-minute intro call. No sales pitch. We figure out whether we are a fit, fast.
