I'm a Senior Software Engineer with 9+ years of experience, mainly focused on Android (Kotlin/Java) but equally comfortable across the full stack with React, Next.js, and Node.js. Over my career I've worked on 30+ production apps across loyalty and fintech, digital banking, smart city IoT, EdTech, and enterprise software. I've led Jetpack Compose migrations across hundreds of screens, driven multi-module restructuring that cut build times by around 30%, and managed offshore teams of 4-5 engineers while working closely with stakeholders and clients. I hold a Backbase Certified Android Engineer certification and have deep hands-on experience with payment terminal integrations, EPOS systems, AI/ML on device, and real-time communication. I care about writing code that's clean, maintainable, and actually works in the real world.
