I need a developer to finish building a private GPT-based system on my DigitalOcean server. Most of the architecture and idea is already defined. I was close to building it myself. This is NOT from scratch — it is completion + proper setup + integration. CORE GOAL Create a system that: - Stores and indexes all documents (PDF, images, emails) - Uses GPT (API fallback) to analyze and recall information - Maintains persistent memory across all chats - Syncs structured data automatically to Notion REQUIRED FEATURES 1. DOCUMENT INGESTION + OCR - Upload PDFs/images - Extract text (OCR) - Store + index data 2. MEMORY + SEARCH - Vector database (Chroma / pgvector or similar) - All files indexed and searchable - All chats share same memory 3. NOTION INTEGRATION (IMPORTANT) - Auto-create/update database entries - Store: - timelines - entities (people, cases) - structured data Using paid Notion account is OK (preferred for speed) 4. GPT INTEGRATION - Use OpenAI API - Answer questions using stored data - Access full indexed memory 5. AUDIT LOGGING - Track: - chats (timestamped) - file uploads - system actions 6. EMAIL PARSING (BASIC) - Read emails (IMAP or forwarding) - Extract + store content - Index into system ADDITIONAL REQUIREMENTS - Basic web chat interface (like ChatGPT) - Must work in browser (desktop + mobile friendly) - Simple UI, no complex design needed USE CASE - System will be used for structured document analysis (legal/case-related data) - Must support timelines, entities, and cross-referencing WHAT IS NOT REQUIRED (FOR NOW) - Advanced file system control (rename/move/delete) - Complex UI - Multi-agent system - Full automation Keep it simple, working first TECH STACK (FLEXIBLE) You can choose best approach, but expected: - Python backend (FastAPI preferred) - Vector DB (Chroma / pgvector) - OpenAI API - OCR (Tesseract or similar) - Notion API - DigitalOcean deployment IMPORTANT This system must: - Work reliably - Be simple - Avoid over-engineering - Focus on core functionality only FUTURE - This is Phase 1 - More work available after completion (upgrades and improvements)
