## Profile

Product engineer and founder with 15+ years taking difficult software and
systems from incomplete requirements through production and support. At
Technomancy IT, I have often been the only engineer or technical lead, owning
discovery, architecture, React/Next.js frontends, TypeScript/Node.js services,
APIs, PostgreSQL data, authentication, integrations, infrastructure,
deployment, debugging, and the operational work after launch. I have helped
teams ship fundraising systems used in raises totaling millions of dollars and
have built or secured applications where money, purchasing, ownership, and
transaction paths required careful handling.

I work directly with U.S.-based clients, explain technical decisions clearly,
and personally perform the work. I do not subcontract.
