At 4Sale, I re-architected the legacy Android monolith into 46 Clean Architecture modules and built a Server-Driven UI platform with 17 component types. It lets the backend control production layouts, so supported screens can go from days to hours to build.

I lead a four-engineer chapter across Android architecture, performance, code quality, and releases. I led work that cut cold start by 37% and improved crash-free performance to 99.65%, while bringing AI-assisted implementation and review into the team's workflow.
