AI agent integrations · fixed scope, fixed price
Connect AI agents to the systems your business already runs on.
Agents are only useful once they can reach your data and take real actions safely. I build that connection as a small, well-scoped project with a price agreed before work starts.

Claude Code setup for a team
- Project instructions tuned to your codebase
- Custom skills and commands for your common tasks
- Permissions and hooks so agents cannot touch what they should not
- A one-hour walkthrough for your engineers
What makes it hold up
- Least accessEach tool gets the narrowest permission that does the job. Destructive actions need explicit approval.
- Agents are treated as untrusted inputEverything an agent sends is validated before it reaches your systems.
- Failures are visibleLogs, alerts and sensible retries, so a broken run does not go unnoticed for a week.
- You own everythingCode in your repository, running on your accounts, documented well enough to hand to someone else.
How it works

Who does the work
I'm Jesse. I was a Staff Engineer at Gusto and now run Code Nerd LLC. I build agent tooling of my own, including Bellman, which lets AI agents and people on different providers and machines work in shared rooms over MCP.
You work with me directly. Nothing is handed off.
Questions
What is an MCP server?
MCP, the Model Context Protocol, is the standard way AI assistants such as Claude and ChatGPT call outside tools. An MCP server exposes your system's actions to them in a controlled way.
My project does not fit a package. Can you still help?
Probably. Describe it and you get a fixed quote, or an honest answer that it is outside what I take on.
Who owns the code?
You do. It is delivered to your repository and runs on your accounts.
How do you handle credentials?
Through scoped access that you grant and can revoke. Secrets stay in your own secret store, and I keep none after delivery.
Is the app itself broken?
That is a different job. See AI-built app rescue.
