What I'm looking for

I'm looking to build scalable backend and distributed systems where I can improve reliability, performance, and automation for high-volume customer or financial workflows.

At Angel One, I build Go-based backend systems for customer onboarding, compliance, and financial workflows. I reduced CDSL fulfilment processing time by over 90%, from 10 minutes to under one minute, through parallel batch processing, workflow orchestration, and error recovery.

I've orchestrated Account Aggregator integrations for 100K+ monthly users, automated CDSL data processing for 25K+ daily records, and built WhatsApp and AWS SNS notifications reaching 500K+ users each month. I also improved exchange-file workflows, reduced NSE/BSE UCC push failures by 40%, and optimized AWS Lambda and S3 document processing latency by 20%.

Earlier, I built automation workflows at MAQ Software and a data anomaly detection platform at Acko. I work across Go, microservices, distributed systems, PostgreSQL, Redis, AWS, and REST APIs, with a focus on reliable systems and measurable operational improvements.
