Senior Mobile Engineer (SDE 3) | Ex-Razorpay | Fintech & Payments | Kotlin, Jetpack Compose, KMP, SwiftUI

About

6 years. Two high-stakes domains - fintech and edtech. One consistent focus: Mobile Apps that hold up when it actually matters. At WEX and Razorpay, I've worked on the kind of systems where a bug isn't just a bad day, it's a failed payment, a blocked merchant, a user who never comes back. That context sharpens how you think about architecture, performance, and trade-offs. Most of my work lives at the intersection of clean mobile architecture and messy real-world constraints - legacy codebases that need modernizing, payment flows that need to be airtight, apps that need to stay fast under load. I work in Kotlin, lean heavily on Coroutines, Flows, Compose, and care a lot about building systems that teams can actually maintain. I also contribute to iOS when needed, because good mobile engineering is good mobile engineering regardless of platform. What I'm drawn to: hard architecture problems, high-reliability systems, and teams that take their craft seriously. Core focus areas: → Android architecture & system design → Payments, fintech & POS systems → Kotlin, Coroutines, Flow & Jetpack → Performance, stability & security → Mentoring & technical ownership
