About

Murugesh Aravind

I'm a Senior Frontend Engineer based in India, with 8 years building banking and enterprise platforms where performance, security, and accessibility are non-negotiable. My strength is taking tangled legacy codebases and making them fast, tested, and maintainable — without burning the team in the process.

Outside of client work I'm exploring the full stack through AWS projects and open-source contributions. My default is: write the test first, ship behind a feature flag, and never let a migration touch production without a rollback plan.
