What I'm looking for

I'm looking to build reliable, scalable backend and distributed systems, lead end-to-end delivery, and solve meaningful performance, security, and cloud infrastructure challenges.

At Deloitte Touche Tohmatsu India LLP, I lead end-to-end backend systems for a client-facing workflow scripting tool used across 10+ enterprise clients and 10k+ users. I’ve shipped 15+ features in Node.js and Express.js, improving task execution speed by 25% and reducing manual intervention.

I architected an event-driven data pipeline for 55k+ Deloitte India employees using Node.js, Python, Kinesis, Lambda, and OpenSearch, reducing query latency by 30% and AWS costs by about 20%. I also lead and mentor four developers, make microservices architecture decisions, and build secure authentication and authorization workflows.

I build resilient systems beyond work, including JobFlow, a distributed task processor with BullMQ, Redis, MongoDB, retries, and dead-letter queues, and Cinematch, an AI-powered movie recommendation platform.
