About Me

I'm a Mobile Application Developer with 7 years of experience in building native Android (Java/Kotlin) and cross-platform Flutter (Dart) applications. I have a strong passion for creating user-friendly, scalable, and high-performance apps for both Android and iOS.

Currently, I'm working at Teamlance, developing and maintaining production-level mobile apps that are live on the App Store and Google Play.

In addition to mobile development, I'm also skilled in backend API development using Node.js and Express.js, enabling me to work across the full stack and build complete end-to-end solutions.

I hold a B.Sc. in Computer Science and Engineering from Bangladesh University (BU) and completed a certified mobile development course from BITM (BASIS). I'm always open to learning new technologies and contributing to impactful projects.
