What I'm looking for

I am seeking a collaborative engineering role building scalable, real-time web or mobile systems with opportunities to work on end-to-end features, low-latency communication, and cloud-native deployments.

I am a full-stack developer specializing in building real-time systems and scalable web applications using React, React Native, Node.js and cloud platforms. I have delivered production features for SaaS and education platforms, integrating real-time video and chat using Agora and optimizing frontend performance with reusable component libraries.

During internships I implemented token-based authentication, Firebase notifications, Redis caching, Prisma ORM, and AWS S3 uploads, and supported hundreds to thousands of concurrent video/chat sessions with low latency. I published a TypeScript-first React Native UI library to NPM and engineered a resilient real-time chat platform with Socket.IO and Redis.

I combine competitive-programming rigor (high ranks in HackerCup, Kickstart and college contests) with hands-on cloud and DevOps experience across GCP and AWS, and I seek to contribute pragmatic, well-tested solutions in collaborative teams.
