About this gig
Want to add real AI to your product built properly, not just a thin chatbot wrapper?
I'm an AI engineer building production LLM systems with Claude and GPT: clean API integration, RAG that answers from your own data, and agents that take real actions through tool-calling (MCP).
What I can help with:
- Claude & GPT API integration into your app or workflow
- RAG / "chat with your documents" with source citations
- Vector databases, embeddings, and semantic search
- AI agents and tool-calling (MCP, function calling)
- Prompt engineering, evaluation, and guardrails
- Deployment, monitoring, and cost control
Why work with me:
With 1,400+ completed Fiverr orders and 850+ positive reviews, I turn AI ideas into reliable, production-ready systems not fragile demos.
Before ordering:
Message me with your use case, your data or tools, and the outcome you want, and I'll recommend the best approach.

FAQ
Do you use LangChain?
Yes. LangChain and structured agent frameworks are supported.
Can agents connect to external APIs?
Yes. Agents can call APIs, query databases, and automate workflows.
What exactly is RAG ("chat with your documents")
RAG lets an AI answer using your own content — docs, PDFs, a database, a website — instead of guessing. I index your data, retrieve the relevant parts, and the model answers from them, with sources.
Claude or GPT — which should I use?
Depends on your needs (quality, context size, cost, privacy). I'll recommend the best fit, and can support both or switch later.
Will it make things up (hallucinate)?
RAG plus guardrails greatly reduces that — answers stay grounded in your data and cite sources, and I can add "I don't know" behavior for off-topic questions.
Is my data and API key secure?
Yes. You keep your own API keys and data; I follow sensible security practices and can keep everything in your environment.
Can you integrate AI into my existing app or website?
Yes — via API into your app, backend, website, or workflow, with clean, documented code you own.
Do you handle deployment?
On the Premium tier, yes — deployment, monitoring, and cost controls so it runs reliably in production.
Can you build an AI agent that takes actions, not just chats?
Yes — agents that use tools and APIs (via function-calling and MCP) to actually do work: fetch data, create tickets, update records, run steps — with guardrails so they stay safe.
What is MCP and why does it matter?
MCP (Model Context Protocol) is the new standard for connecting AI to your tools and data — backed by Anthropic, OpenAI, Google and Microsoft. It makes integrations cleaner and future-proof.
