I connect AI agents to the real world. If your agent needs to query your database, call your APIs, or use your internal tools, and you need proof it actually works, that's my specialty. One example: I built an MCP server exposing scientific computation tools to an AI agent, so researchers could run analyses by asking questions instead of writing scripts. Another wrapped a company's REST APIs so their agent could act on live data instead of guessing. What I build: - MCP servers — custom tools that give Claude, ChatGPT, or your own agents secure access to your - APIs, databases, and domain software - AI agents and multi-step workflows (LangGraph or custom orchestration) - LLM integrations with proper error handling, retries, and cost tracking - RAG pipelines for chatbots and knowledge-base agents - The Python/FastAPI backends that hold it all together How I make sure it actually works: Most AI freelancers ship a demo and hope. I ship with a test harness (golden datasets, automated evals, and regression tests wired into CI) so when you change a prompt or swap a model, you know immediately if quality dropped. I owned model benchmarks and evals at an AI biotech startup for over a year; testing AI behavior isn't an afterthought for me, it's how I build. How I work: - I talk through the plan before writing code so you always know where things stand - Readable code, tests where they matter, frequent check-ins - Happy to start with a small scoped task so you can see how I work first My home base is Python (FastAPI, Docker, MCP, LangGraph, pytest, GitHub Actions) and the major LLM APIs (Anthropic, OpenAI, Groq, OpenRouter). And I pick up new tools quickly when your project calls for them. Available for hourly and project-based work. Not sure if your use case needs MCP or agents at all? Message me — happy to talk it through first.
