Self-taught AI systems architect and founder who ran the operations floor before writing the code. I build production multi-agent systems and “digital employees” — shipped, with receipts, not demos. Known for solving creatively, recommending the honest right stack (including free and self-hosted), and matching expensive-cloud scale at a fraction of the cost.
