About
I'm a backend-heavy full stack engineer with 4+ years of experience building event-driven systems, microservices, and real-time infrastructure. Most recently at Tata AIG, I owned the motor insurance backend — a Lambda + SQS + SNS document pipeline serving millions of customers with 99.9% reliability.
I care about writing systems that are observable, resilient, and fast. I also built an AI-powered chatbot (live on this page) that lets recruiters and collaborators ask me anything — a project I ship, maintain, and iterate on.
When I'm not building backends, I'm thinking about distributed systems, rate limiting algorithms, and how to make software that scales gracefully under pressure. I hold an MCA from Graphic Era Hill University and a BCA from MJP Rohilkhand University.
Experience
Software Engineer
- Built event-driven Lambda + SQS + SNS document pipeline for the motor insurance vertical (₹8,000 Cr+ annual revenue), serving thousands of customers daily with 99.9% delivery reliability.
- Designed reporting pipeline generating 70K+ record reports, reducing sync-failure detection time by 70% across downstream systems.
- Integrated NestJS/ReactJS support portal with 3 core systems via real-time event streams, cutting MTTR by 40%.
Associate Consultant
- Built server-side microservices for end-to-end quote generation and issuance, automating underwriting logic across 5+ product lines and cutting quote turnaround from days to minutes.
- Delivered a full-stack CRM replacing a legacy platform with rule-based orchestration and priority queues, improving resolution efficiency by 60%.
- Automated endorsement processing for millions of insurance records, reducing manual intervention by 50%.
Jr. Node.js Engineer
- Built backend services for 3 Web3 applications from scratch, handling 50K+ monthly active users at 99% uptime.
- Set up Redis pub/sub WebSocket infrastructure for real-time messaging across distributed instances — sub-50ms latency.
- Scaled ride-hailing backend to 10K+ concurrent WebSocket connections via message queues with zero data loss in matching flows.
Projects
Featured Project
AI Portfolio Chatbot
A Gemini-powered AI assistant embedded into this portfolio that can answer any question about my skills, experience, and projects in real time. Built with a custom knowledge base, semantic caching (Redis), conversation memory, and sub-second response optimization — deployable via Vercel serverless functions.

Featured Project
Distributed Rate Limiter
Production-grade distributed rate limiter using Redis + Lua scripting to enforce atomic throttling across horizontally scaled microservices — zero race conditions, regardless of replica count. Validated 1M+ req/s capacity via Autocannon load testing with full fault tolerance.
Other Projects
NFTwist
NFT marketplace for social content. Users mint NFTs from posts, reels, and stories — with built-in auction and secure blockchain settlement.
SharedChat
Real-time messaging app with group chats, DMs, and media sharing. Built on Socket.io with Redis pub/sub for distributed message routing.
