01 / ABOUT

Who I am

I'm a backend-focused software engineer specializing in payments, distributed systems, and cloud infrastructure. I currently build SwiftFlow, a centralized payment platform that powers transactions across Mutual Funds, SIF, AIF, and NPS for 25+ AMCs — unifying UPI, cards, and net banking behind a single integration.

My background spans real-time data engineering, performance tooling, and application security. I care about reliability, observability, and shipping systems that hold up under production load.
