Cover image for Since January, I haven’t taken
Since January, I haven’t taken on a new contract not because I’m not looking, but because I’m focused on finding the right projects. I’m a Senior Mobile Engineer working with native iOS (Swift), Android (Kotlin) and cross-platform(React Native, Flutter) when needed, building scalable, production-ready apps with clean architecture. I’ve worked on real-world apps with complex flows, offline support, and long-term maintainability in mind. I’m currently open to new opportunities ideally long-term collaborations with startups or companies building serious mobile products. Attached is one of my current ongoing projects, Valto, an offline-first budget management app I’m building. If you’re working on something interesting or know a team that needs strong mobile expertise, I’d be glad to connect. Thanks!
