Backend-focused fullstack engineer. I build secure payment systems and APIs for fintech — the kind where a bug costs real money.
I'm a fullstack developer at a fintech startup, working mostly on the backend. Day to day that means payment integrations — netbanking and UPI redirect flows, webhooks, mandate handling — and the KYC and identity-verification flows around them.
The APIs I write are security-first: CSP, auth hardening, rate limiting. FastAPI with PostgreSQL and Redis, containerised with Docker and CI-ready. When a feature needs both ends, I build the React / Next.js frontend too.
Razorpay, Stripe and Cashfree end to end — including the failure cases most devs skip.
Build or audit FastAPI / Django REST APIs for security gaps.
Track down and fix broken webhook and redirect flows.
React frontend + Python backend + PostgreSQL, shipped as one piece.
One CLI to manage all your SSH identities, keys and server connections.
Payment redirect flows, webhooks, mandates and identity verification, in production.
Backend, payments and security — the failure cases tutorials leave out.
Payment integrations, API security, a broken webhook flow, or a full-stack feature end to end — send me the details.
