About this gig
Want an AI agent that actually understands your business not just a chatbot that repeats FAQs?
I'm Rifah Tasnia Prova, a full-stack AI developer and solutions architect with 6+ years of experience building production systems currently working across two companies as an AI developer and architect.
I design and build:
- Autonomous AI agents using LangChain, LangGraph, and AutoGen
- RAG-powered knowledge agents that answer from your documents, data, or knowledge base
- Multi-agent systems where specialized agents collaborate on complex, multi-step tasks
- Business process automation agents that handle real workflows not demos
What sets me apart: I don't just connect an LLM to a prompt. I architect the system memory, tool access, retrieval, error handling, and how agents hand off work to each other so your agent is reliable enough to run in production, not just a proof of concept.
Tech I work with: LangChain, LangGraph, AutoGen, OpenAI, Claude/Anthropic, RAG pipelines, vector databases (Pinecone, Supabase, Weaviate), Python, REST APIs.
Message me with your use case before ordering, and I'll help you scope the right package whether that's a single focused agent or a full multi-agent system.

FAQ
What's the difference between this and a regular chatbot?
A chatbot replies to messages. An agent reasons, uses tools (search, APIs, databases), retrieves knowledge, and can complete multi-step tasks on its own — that's what I build here.
I don't know which framework I need (LangChain vs LangGraph vs AutoGen) — can you help me decide?
Yes — send me your use case and I'll recommend the right architecture before any code is written.
Can the agent connect to my own data or internal tools?
Yes — I build RAG pipelines connected to your documents/data, and can integrate APIs, databases, or internal tools as needed.
Do you provide the underlying LLM, or do I need my own API key?
You'll need your own API key (OpenAI, Anthropic, etc.) for ongoing usage costs — I'll guide you through setup if you're new to this.
Will I be able to maintain/update the agent myself afterward?
Yes — I deliver clean, documented code plus a setup guide so your team (or future developer) can maintain and extend it.
