Mobile App Developer with 12+ years building apps loved by millions. Proven Track Record: Built apps serving 500K+ monthly users, streaming millions of hours of video, and processing $2B+ in transactions. Founded buzdy.com (fintech platform operating across 20+ countries).

I work with founders whose product, engineering, or operations are stuck between vision and execution. Over the last 12+ years, I’ve built and scaled technology businesses from zero — including growing an engineering organisation to 30+ people, managing multi-program delivery across healthcare, IoT, commerce, and enterprise systems, and operating simultaneously across founder, CTO, product, and execution responsibilities. I’m not a task-based freelancer. I step into ambiguity, identify what’s slowing execution, and bring structure, clarity, and operational momentum. Typical problems I help solve: * Product direction is unclear * Engineering teams are active but outcomes are inconsistent * Founders need a technical and operational counterpart * Systems are over-engineered or misaligned with business realities * Cross-functional execution is breaking down * Teams need senior judgment during high-ambiguity phases I’ve worked across: * Healthcare platforms * IoT ecosystems (350K+ deployed devices) * B2B procurement systems * AI-enabled and agentic workflow platforms * Mobile and web products * Multi-vendor technical environments Areas I commonly own: * Fractional CTO responsibilities * Product and technical strategy * Engineering execution management * Technical program leadership * Team structuring and delivery governance * Founder-to-engineering translation * Zero-to-one roadmap execution * Operational diagnosis and process design Tech fluency includes: AWS, GCP, Node.js, PHP, Flutter, React Native, PostgreSQL, MongoDB, system architecture, AI-assisted engineering workflows, and large-scale delivery operations. If you need someone who can operate across strategy, product, engineering, and execution — without needing a heavily defined brief — we should talk.
