Fractional CTO & Full-Stack Dev | Architecture to Delivery

Your project is stuck, behind schedule, or built on a shaky foundation. I fix that — and ship it. Most founders and product teams don't need more developers. They need someone who can look at the full picture — technical, product, and business — and make the right calls fast. That's what I do. With 18+ years building and shipping digital products — SaaS platforms, fintech tools, real estate systems, marketplaces — I operate as a product-minded technical lead, not a task executor. I don't wait for a spec. I write the spec. What's changed in the last two years: I've fully integrated AI-accelerated development into my workflow. Using Claude Code and modern AI tooling, I now move at a speed that wasn't possible before — MVPs in days, not months. This isn't a gimmick; it's a structural advantage for clients with tight timelines or limited budgets. Where I add the most value: - Projects that are stalled, over-engineered, or stuck in dev-hell — I audit, restructure, and push to release. - Early-stage products where a technical co-founder brain is needed, not just execution. - Founders who know what they want to build but need someone to own the how. - Teams where the product and tech decisions keep getting made in the wrong order. My background spans: Fintech & financial tools · Real estate platforms · SaaS products · E-commerce & marketplaces · Enterprise web applications. I work with a trusted senior development team when projects need full-cycle delivery. But I'm also hands-on — I build, not just direct. P.S. For early-stage founders: I occasionally take on projects at a reduced rate in exchange for a small equity stake. If you're building something real and want a technical partner with skin in the game — let's talk.
