Building scalable, high-performance Android apps used by real people β€” with clean architecture, smooth UX, and battle-tested integrations like Retrofit, Firebase & Google APIs.

01 / About
Who I Am

I'm Srijan Chakraborty, an Android Developer based in Kolkata, India with 3+ years of professional experience crafting mobile applications that are fast, reliable, and delightful to use.

I specialize in Java and Kotlin for native Android, with deep experience in API integration using Retrofit and Volley, payment gateway integration (PhonePe), and leveraging the full Firebase ecosystem.

Beyond Android, I've shipped cross-platform apps using Flutter. I've led cross-functional teams, improved system performance by 25%, and reduced bugs by 30%.

I hold a B.Tech in Electrical Engineering from MAKAUT, West Bengal β€” which taught me to think in systems and solve problems from first principles.
