Softwareengineerwho ships

I build and ship full products end to end. Next.js and React on the front, distributed systems, real-time services and AI pipelines in Node.js and TypeScript behind them. B.Tech student at Assam Engineering College, Guwahati.

01About

Systems that hold up
under load.

I work across the whole stack: typed React and Next.js interfaces on one end, authorization pipelines, caching and rate limiting, message queues and WebSocket state on the other. Owning both ends means the contract between them is something I design rather than inherit.

Alongside that I compete regularly — 500+ problems on LeetCode, Specialist on Codeforces — and mentor students in DSA and software engineering at my college.

Software Engineer Intern

VRIXAALABS PVT LTD · HYBRID

01Engineered 3 production-oriented backend improvements in a Node.js/TypeScript microservices platform — centralized RBAC authorization, utility refactoring, and global Redis-based rate limiting.
02Strengthened distributed-system infrastructure with Redis Pub/Sub, Socket.IO Adapter and clustered-cron strategies, global request throttling, and MongoDB connection-pool tuning.
03Architected a centralized permission evaluation pipeline aggregating memberships, entity-role assignments, and role-derived permissions; exposed the effective permission set through GraphQL and integrated it into entitlement authorization, eliminating fragmented permission evaluation across backend flows and improving consistency.
