Servicing Copilot | Senior Full-Stack Contractor | REMOTE (EST overlap required) | $5k paid bake-off → ~6 month contract | CAD $130-180/hr I'm building an AI-native operations tool for private mortgage lenders. MVP targets two workflows that eat servicing staff time: NSF collections follow-up and renewal management. I run a Canadian private lender as my day job, so the product is built against a real shop with real data and real users. Self-funded. No VCs, no board. The data model is locked (20 tables, multi-tenant by lender_id, idempotent CSV imports, append-only event log). Wireframes in progress. Hiring one engineer for the full ~6-month build via a paid bake-off: $5k flat for ~1 week of work, 2-3 candidates in parallel, winner takes the engagement. Losing candidates get paid in full and keep their work. Trial scope: CSV loan tape import with idempotent upsert + audit, one case detail screen, one LLM call classifying a borrower email reply with structured output, activity log driven
