What I'm looking for

I’m interested in backend engineering, distributed systems, system design, and scalable architecture.

At Chrp Technologies, I re-engineered image rendering to overlay stored metadata on original images, eliminating duplicate processed-image storage in Azure Blob Storage and reducing storage costs by 50%. I also built an independent PDF generation micro-service from scratch, replacing the Puppeteer/Chromium-based architecture and improving report generation performance by 8×.

At American Express, I worked on payment network systems, including Auth on Credit and Zero Value Account Verification. I implemented real-time tax enrichment impacting 10M+ transactions annually and built integration-testing microservices that reduced manual effort and improved delivery efficiency.

I graduated from Indian Institute of Technology, Guwahati, with a BTech in Chemical Engineering. I’m interested in backend engineering, distributed systems, system design, and scalable architecture.
