I'm building frontend-heavy full-stack products at Playlist Technologies, where I audited the frontend codebase, identified 14 modernization opportunities, and created a three-phase upgrade roadmap for React, build tooling, and TypeScript.

I also drove a cross-platform architecture initiative across React, iOS, Android, and a Ruby on Rails BFF, and created reusable Claude Code agent skills adopted by a 16-member team.

Previously at IDFC FIRST Bank, I improved React Native load performance by 40% for 2.8 million active users, reduced deployment time by 60% through federated modules, and achieved 70% code reuse between web and mobile.
