What I'm looking for

I seek backend-focused roles building scalable payment systems and microservices in collaborative, fast-paced teams that value code quality, mentorship, and impact; I want to work on payments, ML integrations, and production reliability.

I am a Computer Science graduate with hands-on experience building high-performance payment systems and scalable microservices. At Juspay I integrated multiple payment gateways, refactored webhook flows to prevent race conditions, and helped migrate legacy services into Dockerized architectures to improve reliability and deployment speed.

I build pragmatic solutions that serve millions of users and ship production-critical fixes under pressure. My projects include an ML-driven signature extraction pipeline (YOLOv8, 95% accuracy), a MERN real-time chat app, and an AI data analysis tool using OpenAI and LangChain.
