About

🚀 Senior Software Engineer at Uber | iOS | Backend (Go) | React-Native 🚀 I’ve been building software since 2017, starting out as an iOS developer and growing through roles where I got to experiment, fail fast, and learn a lot. Over the years, I’ve worked across healthcare, e-commerce, fintech, and mobility, picking up experience not just in iOS (Swift, Clean Architecture, VIPER, MVVM) but also in backend systems and even some mobile web tinkering for fun. Today, I’m a Senior Software Engineer at Uber, where I work on both iOS and backend features that power everyday experiences for millions of riders and drivers worldwide. What excites me most is solving real problems — making things simpler, faster, and more useful. Along the way, I’ve been lucky to earn various recognitions and the chance to lead features, mentor peers, and collaborate with cross-functional teams. But at my core, I just love working on ideas that add value — whether it’s a big product launch or a side project hack. If you’re building something meaningful and want to swap ideas, I’d love to connect.
