I’m a senior software engineer who loves building AI-powered, end-to-end software systems. Over the past decade I’ve shipped scalable back-end services, engaging front-end experiences, and data-driven products, always focusing on clean design, reliability, and fast delivery. I enjoy turning hard problems into simple, maintainable solutions and mentoring teammates along the way. Today I balance multiple leadership and hands-on roles across ventures, including STXN and CleanApp, while contributing as a Principal Engineer. My toolkit spans Rust, Go, C++, Python, Java, JavaScript/TypeScript, and cloud platforms (AWS, Google Cloud, Azure). I’m deeply interested in AI/ML, blockchain, and building robust architectures that scale with business needs.
