Custom AI development when off-the-shelf tools are not enough

I build custom AI systems in Python with LangChain, LangGraph, and the OpenAI Agents SDK when a platform cannot do the job cleanly.

An API request and retrieved documents feed a custom Python service built with LangGraph. Evaluation and logging run alongside, and the service returns grounded responses and calls custom tools.

OVERVIEW

A platform is the right answer most of the time. When the logic is unusual, the integration is messy, or the data cannot leave your infrastructure, a custom build is the answer instead.

I write production Python: agents, RAG pipelines, APIs, and the glue that connects systems that were never meant to talk to each other.

WHEN THIS HELPS

Signals this is worth automating

  • A workflow outgrew what a no-code platform can do cleanly.
  • You need an agent with custom logic, memory, or evaluation.
  • A tool has no API, so something has to bridge it.
  • Data has to stay on your own infrastructure.
  • You need an API or service your product can call.

WHAT I BUILD

What the system includes

01

Custom agents with LangChain, LangGraph, and the OpenAI Agents SDK.

02

Multi-step and multi-agent workflows with human-in-the-loop checkpoints.

03

RAG pipelines over your documents and databases.

04

FastAPI services and internal tools your team can call.

05

Integrations for systems with no clean API.

06

Evaluation and observability so quality is measured, not guessed.

HOW IT WORKS

From process to system

01. I define the system

We agree on the outcome, the constraints, and where the code has to live.

02. I choose the stack

Frameworks and models follow the problem, not the other way around.

03. I build and test it

The system is built in steps and tested against real cases before it goes live.

04. I hand it over documented

You get the code, the documentation, and a walkthrough so your team can run it.

COMMON QUESTIONS

Common questions

When should I choose custom over a platform?

When the logic is unusual, the integration is messy, or a platform cannot meet a technical or data constraint. Otherwise a platform is faster and cheaper.

Which frameworks do you use?

LangChain, LangGraph, and the OpenAI Agents SDK most often, and CrewAI or others when they fit. The choice follows the task.

Do I own the code?

Yes. It runs in your repository or your infrastructure, and you get documentation and a walkthrough.

How much does custom AI development cost?

It depends on the scope, the integrations, and the data work. You get a fixed quote after scoping.

WHERE IT FITS

Where this fits

Best for teams that have outgrown a platform, need custom logic, or have a technical constraint a hosted tool cannot meet.
