About me
Backend first. AI when it actually helps.
I'm Sarthak Mittal, a software developer in Gurugram. I spend most days on production APIs — Java, Spring Boot, Postgres — and the rest wiring LLMs into workflows that used to be a pile of tickets.
At CarePay I work on loan onboarding, NBFC integrations and RAG-powered application journeys. Before that I was at Leverage Edu, keeping internal tools stable and shipping REST features with product and QA. MCA from Thapar (8.6), BCA from MMU (9.45).
