As a Fractional CTO, I guide companies from strategic vision to scalable execution. My focus is on building the tech, teams, and strategy that drive sustainable growth.
This strategic leadership is grounded in deep, hands-on experience as a full-stack engineer over the past 10+ years. I specialize in architecting and building robust web applications powered by modern JavaScript ecosystems and the practical implementation of AI.
This dual perspective, seeing the big picture and mastering the technical details, has enabled me to lead startups and enterprise teams in gaming, travel, finance and other domains to successfully build and launch end-to-end products.
