What I'm looking for

I seek engineering leadership roles building AI-enabled mobile platforms (Flutter/iOS) with end-to-end ownership, strong technical teams, and fast-paced product impact.

I am a full-stack mobile engineer who architects and ships production applications at scale, building AI-powered platforms and revenue-driving features across PropTech and FinTech. I led delivery of a unified Flutter codebase powering three mobile apps and two web clients, integrated LLM-based agents for automation, and drove product features at Revolut that increased profits and conversion.

I own end-to-end product lifecycle responsibilities—from architecture and CI/CD to App Store/Google Play publishing—and mentor engineers to accelerate delivery. My work has supported NVIDIA Inception recognition and consistently reduced development time, binary size, and manual processing through modular architecture, AI integration, and performance optimizations.
