(S) In my last role, we were scaling the frontend team from 4 to 10 engineers, and our culture needed to evolve to maintain quality. (T) I wanted to help create an environment where we shipped quickly but kept a high bar for code and collaboration. (A) I thrive in a culture with clear standards, open feedback, and autonomy. I contributed by helping define our frontend guidelines: we agreed on TypeScript usage, testing thresholds (e.g., 70%+ coverage on core modules), and accessibility requirements. I introduced lightweight RFCs for bigger changes so everyone could comment asynchronously. In code reviews, I focus on clarity, maintainability, and user impact, and I explain “why” behind suggestions. I also ran occasional lunch-and-learn sessions on topics like performance profiling. (R) Over six months, our average PR review time dropped by about 25%, and we reduced post-release frontend bugs per sprint by roughly 30%. The team’s internal survey scores around “clarity of standards” and “knowledge sharing” improved by around 15 percentage points.
