What I'm looking for

I want to build secure, high-quality cross-platform mobile apps end-to-end—owning feature delivery, integrating APIs and payments, and confidently shipping to app stores with a collaborative, quality-focused team.

I’m a results-driven, mid-level Mobile Application Developer with over four years of experience architecting and delivering cross-platform mobile applications for Android and iOS. I focus on shipping secure, scalable apps that feel fast, polished, and dependable.

I build end-to-end features independently—from concept to App Store and Google Play deployment. I’ve integrated RESTful APIs, payment systems, biometric authentication, and third-party SDKs, and I’m comfortable managing remote project delivery while keeping quality and timelines on track.

In banking and health products, I’ve improved transaction success and reduced payment/login friction through thoughtful engineering—like biometric Fingerprint/Face ID, optimized performance, and responsive UI/UX (including Light & Dark mode). I also deliver real-time experiences with tools such as WebSockets and Firebase, and I prioritize offline resilience with local storage.

I bring a product-minded, collaborative approach to development, and I’ve supported others by training 50+ students in Flutter and Dart. My goal is to keep improving how users interact with mobile products—through strong architecture, careful testing, and user-focused micro-interactions.
