AI Developer Needed – Build RAG-Based Xactimate Line Item Translator (OpenAI + Vector DB) - Contract to Hire

Apply Now
I own a restoration company and use Xactimate daily for fire and water loss estimating. I want to build an internal web-based AI tool that converts plain English scope notes into the closest matching Xactimate line item codes. Example: Input: “Remove soot damaged tile floor in kitchen. 4 ft flood cut drywall. Replace 5 inch baseboard.” Expected Output (structured JSON): • FCT DEM • DRY 4 • VNB R&R This will be a private internal tool (not public SaaS at this stage). Project Scope The application should: 1. Accept paragraph-style scope notes 2. Break the text into individual scope tasks 3. Identify action types (DEM, REP, R&R, D&R) 4. Use semantic search to match each task to the closest line item from a provided Xactimate dataset 5. Return structured output (code, description, confidence score) 6. Flag ambiguous matches instead of hallucinating codes The system MUST use a Retrieval-Augmented Generation (RAG) architecture. The AI should NOT guess or invent codes. It must only select from the provided database. ⸻ Technical Requirements Preferred Stack: Backend: • Python (FastAPI preferred) • OpenAI API (GPT-4 class model) • Vector database (Supabase, Pinecone, or similar) Frontend: • Simple web interface (React, Next.js, or similar) • Text input field • “Translate” button • Results panel with structured output Database: I will provide a private export of: • Line item code • Description • Category • Region tag This must be embedded and stored in a vector database for semantic retrieval. ⸻ Required Experience You must have: • Proven experience building RAG systems • OpenAI API integration experience • Experience with vector databases • Experience designing AI guardrails to prevent hallucinations • Ability to explain architecture clearly Please include examples of similar AI systems you’ve built. ⸻ Deliverables • Functional web-based MVP • Vector search implementation • AI prompt architecture • Clear deployment documentation • Source code ownership transferred to me ⸻ Timeline 3–6 weeks preferred. ⸻ Budget $5,000–$10,000 depending on experience and proposal quality. Open to fixed-price proposals. Apply Now Apply Now
