What I'm looking for

I’m looking for a team where I can build and scale Flutter/Android consumer apps, apply clean architecture and state management, optimize performance, and ship reliably to Google Play and the App Store.

I’m a Mobile Application Developer with 5+ years of experience building and maintaining production Flutter and native Android applications. I’ve been focused on shipping real, user-facing products while keeping architecture clean and maintainable.

At Rokomari.com, I collaborate within a 25-member engineering team to develop, scale, and optimize Android & iOS Flutter apps serving 350K+ active users. I restructured legacy code using Clean Architecture & Bloc to improve maintainability and reduce crash rates.

I also drive performance improvements by refactoring REST APIs and data caching, reducing API calls by 70% (from 27 to 8) on the product details page. This work has helped me consistently improve page responsiveness and load times while supporting ongoing product growth.

Previously, at Genuine Technology & Research Ltd, I engineered and launched enterprise Android/Flutter apps for POS, HR, and Sales—implementing barcode/QR scanning, offline-first SQLite synchronization, push notifications, and PDF invoicing. I bring the same hands-on problem-solving mindset to projects like an e-commerce Flutter app (1M+ downloads) and ongoing experiments with Spring Boot and AI tools.
