What I'm looking for

I'm targeting SDE roles where I can build fast, secure full-stack and real-time products, solve backend and infrastructure problems, and grow through hands-on ownership.

I'm interning at HackerEarth, where I own the end-to-end 1v1 duel flow for VibecodeArena, covering invites, live duels, results, and edge cases such as no-shows and disconnects. I also identified an SSH exposure in sandbox VM terminals that could leak environment variables and API keys.

I built DualDev, a real-time competitive coding platform, and reduced submission-to-verdict latency to a 525ms median across 20 live runs. By moving execution infrastructure to a self-hosted VPS and building a BullMQ and Redis pipeline, I cut costs while improving service latency.

I've also built an AI-powered expense tracker and a full-stack chat application with secure authentication, group conversations, and dynamic rooms. I work across React, Node.js, MongoDB, Redis, Docker, and real-time systems while targeting software development engineering roles.

Owned the 1v1 duel flow end-to-end for VibecodeArena, hardening against edge cases like invite expiry and mid-duel disconnects. Discovered a security vulnerability in sandbox VMs and expanded unit test coverage to 31%.
