(About Me)

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 (Java/Spring Boot, Python/FastAPI), 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.
