What I'm looking for

I'm seeking full-time or contract Software Engineer roles where I can build Flutter mobile products, native integrations, and Node.js backends, lead architecture decisions, improve delivery through CI/CD and testing, and mentor developers.

I've built and shipped mobile products at Time2Mobile, Piogroup Software, Dreambit, and Digis, spanning IoT, real-time messaging, CRM, social entertainment, healthcare, EdTech, and cryptocurrency operations. My work combines Flutter apps with native Kotlin and Swift integrations and Node.js/NestJS backend services.

I've led architecture and Flutter teams, reduced crash rates by 35%+, improved IoT responsiveness by 30–40%, and accelerated releases by up to 50% through CI/CD. I enjoy turning complex product requirements into reliable mobile experiences, from live streaming and payments to AI-powered personalization, while mentoring engineers and owning delivery end to end.
