What I'm looking for

I seek a senior engineering role where I can lead cross-functional teams, build scalable real-time systems, mentor developers, and drive product performance and user engagement.

I am a Senior Mobile Developer with eight years building high-performance web, iOS, and Android applications focused on clean, scalable code and excellent UX.

As a team lead, I architected real-time systems using WebSockets and Redis, maintained 99.9% uptime during peak events, and integrated services like Google Maps and Stripe for production platforms.

I have built full-stack solutions using React, React Native, Next.js, Node.js, Python (TensorFlow), and Firebase, and have driven performance improvements—reducing validation response times by 70% and improving app performance by up to 40%.

I mentor teams, design RESTful and GraphQL APIs, manage PostgreSQL/Firestore/Redis databases, and deliver accessible, high-engagement products that scale to thousands of users.
