01About

Nabaraj designs and ships enterprise-scale frontends — the kind with thousands of daily users, strict accessibility bars, and teams spread across time zones. Fourteen years in, the interest hasn't shifted from the first line of React he ever shipped: components that hold up under real traffic, and architecture that a new teammate can understand by Friday.

Focus
Frontend architecture, design systems, performance
Core stack
React, TypeScript, GraphQL
Also builds with
AI-assisted tooling — Copilot, ChatGPT
