ConstraintThe product problem
A Node.js pipeline that ingests Realtracs MLS data, detects historical flip pairs, trains market models, and scores active listings as BUY / REVIEW / PASS for a real estate flip investor (Sam, Middle Tennessee). The engineering challenge is to turn that scope into a legible system with explicit inputs, dependable workflow boundaries, and an outcome that can be inspected and maintained.
SystemThe architecture decision
The reviewed implementation routes input / action through domain & workflow logic, crosses external apis & platform services where required, and produces actionable result / automated outcome.
OutcomeThe operating result
Property Renovation is included as documented engineering work. Its source structure, technology stack, and functional flow are presented here even though no verified public deployment is currently available.
