What I'm looking for

I seek a full‑time mobile role where I can lead development, mentor teams, build scalable Android/Flutter apps, and drive product impact.

I am a Senior Mobile Developer with over six years of experience building high‑quality Android applications using Kotlin and Java and cross‑platform apps with Flutter. I lead teams, implement robust architectures (MVC/MVVM), and deliver user‑focused interfaces while applying Agile/Scrum practices and strong testing and release discipline.

I have delivered secure, scalable solutions across healthcare, logistics, and consumer apps — building custom widget libraries, integrating payments and ML Kit features, and improving performance and reliability. I communicate clearly, mentor peers, and focus on practical, timely solutions that align with business goals.
