How I build
I design every game myself and test it with real kids.
I build with AI agents like Claude, which do work I would once have needed a team for.
I check every fact against real sources and every verse against the KJV.

Why I build
For 15 years I negotiated fuel contracts across the Americas and the Caribbean. The other side had a team. In June 2025 I stepped back so I would stop missing my girls growing up.
Now I build.
My faith shapes what I make: things that are true, good, and worth a child's time.
Background
2010 to 2021, at OceanConnect Marine
I developed the power-plant fuel business across the French-speaking Caribbean and ran it for eleven years.
2021 to 2025, at Hartree Marine
I helped build the desk for the US Gulf Coast, US East Coast and Eastern Canada, and ran most of the Canadian business in French.
2023 to 2025, at Hartree Marine
I opened South America from a cold start, and when I left I was working across five countries.
I negotiated for 15 years in English, French and Italian.
I opened markets and built the relationships that kept them.
I build real products with AI agents, including the three above.
OceanConnect Marine (since merged into KPI OceanConnect) and Hartree Marine are named here for the record only, and the dates are on my LinkedIn. Neither is affiliated with what I do now, and neither endorses it.
I am open to the right conversation: partnerships, market entry, or a negotiation where this mix helps. Get in touch
Most of my trading years were spent at a desk in the United States, buying and selling oil and negotiating contracts across the Americas and the Caribbean.
