Who I Am
A big-tech engineer who went independent to build with you
I'm a software engineer with 20+ years of experience designing and shipping desktop, web, and mobile applications.
I spent years inside large tech companies, then left the corporate world to do what I enjoy most: working directly with people to turn their ideas into real, polished products. No layers, no handoffs — you talk to the person actually building your app.
Whether you're a first-time founder with a sketch on a napkin or a business that needs a complex, production-grade app, I bring the same care: thoughtful architecture, honest advice, and software built to last.
