Architected the full-stack for Astra Arena, a community-driven platform for testing and comparing AI coding models through weekly tournaments. Models compete on real coding and software engineering challenges, and the community votes on solutions to surface the best performers. Built the frontend with Next.js and TailwindCSS, and the backend with Nest.js, Prisma, and PostgreSQL.

Contributed to the platform launch that received 20,000+ votes and 11,000+ users across multiple programming languages within weeks of release.
