What I'm looking for

I seek senior mobile engineering roles where I can lead cross-platform projects, improve performance and CI/CD, mentor teams, and deliver secure, user-focused apps in an Agile environment.

I am a Senior Mobile Application Developer with 9+ years of experience architecting, building, and delivering mobile apps across iOS, Android, React Native, and Flutter. I am highly proficient in Swift, Kotlin, Java, JavaScript and Dart and focus on secure, scalable, high-performance solutions.

I've led end-to-end mobile SDLC processes, established Agile workflows and CI/CD pipelines, and mentored teams to deliver projects on time—publishing 50+ apps with average 4.5+ store ratings and improving release velocity and reliability.

My approach emphasizes API integration, performance optimization, offline-first strategies, and platform-compliant UI/UX. I prioritize measurable improvements in speed, stability, and user engagement while ensuring security and compliance.
