AI-Powered Product Builder

Leodegario
Magsino Jr.

I build products, not just code. Three times a founding engineer, with 13+ years building across fintech, healthtech, and e-commerce — comfortable working in ambiguity, just as comfortable inside process and structure. Now I'm turning that same instinct toward AI: building with new tools, shipping something real.

Where it shipped

Current toolchain

AI is leverage. I decide where it points.

Claude and GitHub Copilot aren't a novelty bolted onto my workflow — they're how I plan, write, and review code every day. They take the boilerplate and the exploration off my plate so my judgment goes where it actually matters: architecture, trade-offs, and the calls that are expensive to get wrong.

Thirteen years of building products taught me what "good" looks like — for the code and for the business behind it. AI didn't replace that judgment. It just closed the gap between having it and shipping it.
