Server systems

WrenchBid — The Negotiator

A server-backed repair-quote negotiation system built around immutable specifications, normalized evidence, auditable leverage rounds, provider webhooks, and tenant isolation.

WrenchBid turns a confirmed repair scope into structured, evidence-linked simulated quotes and explains a ranked recommendation. Counterparties are synthetic in the current build; the system does not claim to call or negotiate with real repair shops in production.

Engineering contribution

What I worked on

  1. Designed the domain model for repair scopes, quote evidence, leverage rounds, and recommendations.
  2. Built server-backed workflows with PostgreSQL, provider webhook boundaries, and tenant-aware data access.
  3. Added deterministic evaluations and explicit capability gates so demo behavior stays auditable.
