What I'm looking for

I am looking for mobile development roles where I can build Flutter apps, work with REST APIs and Node.js/Firebase backends, apply state management patterns, and grow technical skills in a collaborative team.

I am a Flutter/Dart mobile developer with hands-on experience building cross-platform applications, integrating REST APIs, and managing backend interactions using Node.js and Firebase. I have delivered projects including a student app, POS app, and location-based features while applying state management patterns like GetX and Bloc/Cubit.

With a BS in Business Computer, internship experience, and prior PHP/MySQL development for university systems, I combine practical mobile development skills with backend understanding and database management to build reliable, user-focused applications.
