Build Persistent Memory Layer for Conversational AI (Python + DB + APIs) We’re building a persistent memory system for a conversational AI project. The goal is to store and recall key text “memories” with both structured and semantic search. What we need • Backend service in Python (FastAPI or Flask). • Storage: PostgreSQL (structured) + vector DB (Pinecone, Weaviate, Qdrant, or FAISS). • API endpoints to save entries, recall by keyword or semantic match, and list recent. • Dockerized deployment + clear documentation (setup guide + runbook). • Secure handling of secrets (.env, vault). Requirements • Strong experience in Python backend engineering. • Hands-on with vector databases + embeddings. • Proven ability to deliver production-ready APIs. • Comfortable working asynchronously and fully digitally (written updates, no Zoom). Deliverables • Working API + demo (3 saved entries, recall verified). • <500ms recall latency, ≥90% recall accuracy. • Clean repo with Dockerfile, README, and 14-day bug-fix warranty. Budget & Timeline • Budget: $2,000–$4,000 • Timeline: 7–10 days (stretch goal 5)

I'm an AI/ML engineer with extensive experience building production-ready APIs. I'll leverage FastAPI for the backend service, integrating PostgreSQL for structured data and Pinecone for efficient vector search. My approach will prioritize a clean, Dockerized deployment with comprehensive documentation, ensuring secure secret management via .env files. I'll deliver a fully functional API meeting your latency and accuracy targets, including a demo showcasing the key features. Please check my profile and reviews.

Hi, This is Elias from Miami. I’ve reviewed your project details, and from what I understand, you need a Python backend service (FastAPI/Flask) for a persistent memory layer for conversational AI, supporting structured and semantic recall via PostgreSQL and a vector DB, with Dockerized deployment, secure secrets handling, and <500ms latency. I have extensive experience building Python backends, integrating vector databases (Pinecone, Weaviate, FAISS), and delivering production-ready APIs with clean, documented repos. I can ensure reliable, fast recall and a fully demo-ready system within your timeline. A few questions to clarify your requirements: Q1: For semantic search, do you have a preferred embeddings model (OpenAI, Hugging Face, or custom)? Q2: Should the API include versioning or soft-delete of memory entries for audit/history purposes? Q3: Are there specific security standards (encryption at rest, role-based access) you want implemented beyond .env handling? I can start immediately and deliver a clean, fully documented system with demo entries within 7–10 days, including a 14-day bug-fix period. Looking forward to connecting and building this persistent memory layer. Regards, Elias
