Backend + Android | Kotlin | Java | Spring Boot | Kafka | Jetpack Compose | KMP | Microservices
I build production systems end-to-end - Spring Boot microservices and event-driven backends, plus Android apps used by millions. I also publish open-source samples on modern Android patterns.
Staff Software Engineer with 8+ years across backend and Android. At Bazaar Technologies I design Spring Boot microservices for fintech (lending, payments, ledger) with Kafka event-driven flows, clean architecture, and MySQL/PostgreSQL - and ship Android apps used by millions via EasyKhata (5M+ downloads, 400K+ active users). Led our Kotlin Multiplatform (KMP) migration for shared Android/iOS business logic. Deep in fintech: secure transaction flows, certificate pinning, and compliance-grade delivery.
