Backend engineer · Distributed systems

I build backend systems that hold up when things break.

Go, gRPC and event-driven architecture, with the idempotency and crash-safety work that makes those words mean something in production.

A payment failure and mandate recovery agent, built for Razorpay's AI Buildathon. Nine Go services diagnose why a payment failed and run the one bounded, auditable fix that matches the cause, guaranteeing exactly-once financial actions under at-least-once delivery.

About

Aranya Dutta

I'm a final-year CS student at KIIT. Most of what I enjoy sits below the UI: message buses, failure modes, and the unglamorous work of making a system behave correctly when a machine dies mid-batch.

I'm also studying Japanese, aiming to work in Japan. JLPT N5 passed in December 2025, preparing for N3.
