I build software that drives real business outcomes, and I believe AI is a game-changer for how we deliver them. From architecting scalable backend systems to integrating AI-powered solutions, I focus on solving complex problems faster and more efficiently. I take ownership from concept to production, setting up infrastructure, CI/CD pipelines, and the right tools to ensure reliable delivery. With experience spanning fintech, hospitality tech, and IoT, I bring technical depth combined with a pragmatic approach to leveraging AI for automation, smarter workflows, and better developer productivity. Active in the community as a mentor, helping teams embrace both solid engineering practices and the AI-augmented future of software development.
