[For Hire] AI/ML Engineer — RAG systems, AI agents & custom LLM apps (FastAPI, LangChain). Remote, worldwide.

I'm an AI/ML engineer who builds production-ready AI systems end-to-end not just demos. If you have a real business problem and want it solved with AI, I can help.

What I build:

RAG systems chatbots and assistants that answer from your own documents/data instead of hallucinating. Full pipeline: ingestion, embeddings, vector DB, retrieval, deployment.

AI agents automated workflows that handle multi-step tasks (customer queries, data processing, etc.).

Custom LLM apps invoice/document extraction, content generation, internal tools.

Some things I've actually shipped:

A WhatsApp AI agent that handles customer queries 24/7

An AI bookkeeping tool that reads invoice photos and extracts the data automatically

A legal-AI platform with a full RAG pipeline, 25+ API endpoints, and document templates

Stack: Python, FastAPI, LangChain, FAISS/ChromaDB, MongoDB, React/Next.js, and models like Llama (via Groq) and Gemini.

Rate: $25/hr. For well-defined work I also do fixed-price — e.g. a RAG chatbot from ~$300, an AI agent/automation from ~$400, depending on scope. Happy to quote per project.
