Engineering notes, independent builds and questions worth revisiting.
Looking Beyond the Frontend Boundary
An interface is part of a larger system. A reflection on dependencies, design contracts and the independent projects that make those connections visible.
3 min readInside SuperAgent’s Cost-Aware Routing Brain
Intent, skill chains, cross-session memory and model choices: how SuperAgent tries to make AI coding workflows more deliberate and inspectable.
4 min readWhy a Lighthouse Score Is Not the Whole Performance Story
Rendering speed, interaction and reliability belong to the same user journey. Use a performance score to investigate that journey, not to stand in for it.
