Software Development Engineer 1, Frontend at CoinSwitch building PRO trading surfaces and money-flow safeguards.

India

Message

At CoinSwitch, I build PRO trading surfaces across spot, futures, and options, and work across web and mobile. I also delivered features including multi-sub-account futures and Zing live trading signals.

I’ve fixed correctness issues on live money flows, built Node/Express and GraphQL services, and carried production on-call. I use test-first practices and build developer tooling, including a playbook for the React Native to Flutter migration.

At One, I architected OAuth 2.0 integrations across third-party services and developed an LLM-powered pipeline for API documentation. Earlier, at IBM I automated a financial file-ingestion pipeline, and at Philips I automated diagnostic-imaging workflows and built REST APIs.
