Approach
Tech for business. That’s always been my compass. I build products that solve real problems and generate revenue. After years of shipping complex web3 applications and diving into AI, I bring a hands-on CTO perspective to every project: architecture, development, mentoring, and product strategy. Whether it’s bootstrapping a product from zero, advising on technical decisions, or leading R&D on complex systems, I focus on what actually moves the needle.
