Ankit Tamboli
Backend engineer focused on payments and fintech.
I've spent 3 years building systems where correctness actually matters — payment gateways, transaction flows, webhook handlers, and the kind of backend work where a bug isn't just a bug, it's a financial loss.
What I work with
Python · FastAPI · Django · PostgreSQL · Redis · AWS · Docker · CI/CD
What I've built
- PrayasPe — a fintech platform integrating 30+ payment APIs, built for users in areas with no access to traditional banking (think cash withdrawals, bill payments, money transfers — all through a mobile app)
- Blue Membership — a subscription billing system on Razorpay handling the full lifecycle: create, pause, cancel, resume, with idempotent webhook processing so no payment event is ever missed or duplicated
- Fuel card system — a closed-loop payment platform for a logistics company where fleet owners issue prepaid fuel cards to their drivers, topped up via payment gateways and redeemable only at fuel stations
Currently building
Failure-Resilient Payment Processing System — A payment processing system focused on failure — duplicate webhooks, failed retries, double charges. The edge cases that break most systems. Building this to handle them correctly, not just the happy path.
