About this gig
Turn your website into an AI-enabled product: semantic search, document Q&A, LLM-assisted content, and secure backend APIs using RAG, embeddings, and vector DBs. I integrate LLM features into existing sites or build lightweight UIs (Next.js/React) + Node/serverless APIs to handle ingestion, embeddings, retrieval, and prompt orchestration.
What you get: ingestion pipeline for your docs, embeddings, vector DB setup (Pinecone/Qdrant/Supabase), backend endpoints to orchestrate retrieval + LLM calls, frontend components (search box, assistant widget, in-page answers), cost controls (token limits, caching), webhook/key security, and deployment-ready configs.
Tech I use: Next.js, React, Node/Express or serverless, Postgres/Supabase, Pinecone/Qdrant/Weaviate, OpenAI/Anthropic/Mistral (or your provider). I follow production practices: webhook signing, env vars, rate limiting, and minimal logging for privacy.
How we start: send a 1-page brief + sample docs (PDFs/URLs). Ill propose scope, vector strategy, and a demo plan. Deliverables include repo or integration patches, preview URL, and concise handover docs. Message me with your dataset and desired UX.

FAQ
Is this a “chatbot” gig?
No. This gig adds in-site LLM features (semantic search, document Q&A, content assistance). I can build chat-style UIs on request.
Which LLMs/vector DBs do you support?
I work with OpenAI, Anthropic, Mistral and vector DBs like Pinecone, Qdrant, Weaviate, and Supabase.
Will you need my API keys?
You can provide keys or I can set up everything and hand you instructions to replace keys in production.
How do you handle cost and token usage?
I include caching, token limits, and batching strategies; I’ll estimate runtime cost after reviewing your data.
Can you handle private or sensitive data?
Yes, I’ll propose architectures (server-side mediators, redaction rules) to minimize exposure. For strict compliance, we can discuss additional measures.
Will I get the code?
Yes, repo or integration patches are included. Some low-code platforms limit exportability; I’ll confirm before starting.
Do you deploy to my host?
Yes, Vercel, Render, AWS, or your chosen host. Provide access or invite me to the repo.
