You have a working prototype and need it to survive real customers. I join for 3—6 months and leave the codebase sturdier than I found it.
Agencies & studios
White-label AI voice, MCP connectors, n8n orchestration for client work. I've shipped reseller SaaS end-to-end and know where the sharp edges are.
Teams of one-too-few
Fractional Head of Development — architecture, code review, hiring, and the occasional on-call. Remote, calm, documented.
