Senior Android Engineer with 10+ years shipping native and multiplatform apps for fintech, banking, B2B, utilities, and enterprise.

I'm Pushpal Roy, a Senior Android Engineer based in Kolkata, India. A decade in, mostly shipping Android and Kotlin Multiplatform apps across fintech, banking, utilities, and enterprise. I lead Android engineering on a US-based financial services product at Grid Dynamics — building Server-Driven UI components on top of GraphQL, mentoring 8+ engineers, and running technical interviews. Outside the day job, I love listening to music and travelling, and explore new stuff in tech.
