From idea to production
I take a project from requirement to production myself. AI coding agents speed up every stage, while I make the decisions and own the result. I check their work with tests, type checks and CI quality gates, because I know where agents go wrong: logic that looks right but is not, made-up packages, missed edge cases. Security-sensitive parts such as authentication and data migrations I review line by line.
Plan
Understand the problem, split it into tasks and sketch the architecture.
Build
Frontend, backend and database, with types checked from end to end.
Test
Unit, integration and end-to-end tests, plus accessibility checks.
Ship
Containers, CI/CD pipelines and deployments to the cloud or my own server.
Run
Monitoring, updates and the next round of improvements.
