Open to internships & freelance — Kolkata, West Bengal, India
I'm Sayan Mondal, an Information Technology undergrad at Jadavpur University. I build full-stack products end to end — Java and Spring Boot on the backend, React and React Native on the front — with a focus on real-time systems, clean APIs and performance.
Away from the keyboard I keep a steady competitive-programming habit and I've been an outdoor photographer since 2024, chasing landscapes and street frames — a hobby that trains the same eye for detail I bring to interfaces.
