LangChain Developer
I build production LLM applications with LangChain — agents, RAG pipelines and tool-using workflows — with the tracing, evals and structure that take you past the demo and into production.

How I can help
Concrete, hands-on langchain developer work — scoped to your goals and shipped to production.
RAG pipelines
Retrieval chains with the right loaders, splitters and retrievers for your data.
Tracing & evals
LangSmith tracing and evaluation so you can debug and trust what your chains do.
Refactor & harden
Turn a fragile prototype into a maintainable, observable production system.

A free 30-minute call to map your goals, current stack and where langchain support will move the needle fastest.
- 02 Scoped plan
You get a clear, fixed-scope proposal — milestones, timeline and pricing. No vague retainers, no surprises.
- 03 Build & ship
I build in the open with you, shipping working increments weekly so you can use it (and steer it) the whole way.

Common questions
Should I use LangChain or build from scratch?
LangChain shines for complex agents, RAG and orchestration where its tooling and tracing save real time. For simple single calls, a direct SDK is lighter — I'll recommend honestly based on your use case.
Can you fix our messy LangChain prototype?
Often that's exactly the job. I refactor fragile chains into structured, observable code with tracing and evals so it stops breaking every time you change a prompt.
Do you use LangGraph?
Yes. For stateful, multi-step agents LangGraph gives you control and reliability that plain chains can't. I use it where the extra structure pays off.
