I build products end
to end — from the
database to the app
in your pocket.
I’m Rajat Saxena, a full-stack engineer based in Bengaluru with 3 years of experience spanning backend systems (Python/FastAPI, Java/Spring Boot), web frontends (React.js, Next.js), and 3 years of production Flutter development. That backend-plus-mobile-plus-web combination lets me own a feature end to end — from API and database design through to the UI shipped on the Play Store and App Store. I’ve built and operated REST APIs and microservices for production systems serving 10,000+ users, inside Agile, CI/CD-driven teams.

Design
API contracts and data models settled before a line of UI.
Build
Services, clients, and the glue that holds the two together.
Ship
CI/CD, store releases, and the unglamorous reliability work.
Scale
From 300 users to 10,000+ without stopping to rewrite it.
