What I'm looking for

I seek roles where I can lead cross-platform product development, build scalable apps or immersive AR/VR experiences, mentor teams, and work in collaborative Agile environments focused on performance and user impact.

I am a Senior Software Engineer and Game Developer with over eight years building high-quality mobile apps, web platforms, AR/VR experiences, and backend systems. I excel at shipping production-ready products used globally and leading teams through full product lifecycles.

My technical expertise includes React Native, React/Next.js, Android (Java/Kotlin), iOS (Swift), Unity 3D, TypeScript, Node.js, Firebase, and AWS, which I apply to deliver performant, scalable cross-platform solutions.

I have led projects end-to-end — from architecture and CI/CD to performance optimization and deployment — producing measurable improvements such as a 20% increase in user retention and significant load-time reductions for AR apps.

I thrive in Agile environments, collaborating closely with design, QA, and product leadership to translate creative concepts into polished, user-centric experiences across mobile, web, and immersive platforms.
