What I'm looking for

I seek a senior/lead mobile role where I can architect cross-platform solutions, mentor engineers, drive CI/CD and deliver user-focused, high-performance apps.

I am a results-driven lead mobile application developer with over 8 years of experience building high-impact iOS and Android applications using both native and cross-platform technologies.

I architect scalable solutions with MVVM, BLoC and related patterns, and I champion CI/CD and test-driven practices that improved delivery cadence and reliability.

I have led and mentored teams, driving measurable product outcomes — including DAU uplifts, retention gains, and performance improvements — while prioritizing accessibility and user-centered design.

I collaborate closely with product, design and backend teams to translate complex business needs into polished mobile experiences from concept to launch.
