Agentic Engineering Day
A working day on your own codebase. Your engineers take real tickets through coding agents, and we agree which changes a person reviews. You keep the setup and a written review policy.

I run my company on AI agents. I help yours do the same.

What I help with
Two kinds of change, usually in the same company
Most companies have tried chat assistants. Few have moved to agents that read their systems and do the work. That step is part engineering and part organisation, and I have done both.
Engineering teams
For CTOs and heads of engineering
- Coding agents such as Claude Code set up on your own repositories, with the conventions file and architecture decisions they need to stay consistent.
- Several agents working in parallel, with one person reviewing, and a way for them to coordinate across repositories.
- A review policy by risk, so people spend their attention where a mistake is expensive.
- Connections from agents to your internal tools (MCP servers), with limits built into the configuration.
The whole organisation
For CEOs, COOs and digital leads
- A map of which systems an agent can read and act in today, and which ones need an API first.
- Two or three agent workflows in daily use: CRM upkeep, reporting, drafting emails and invoices.
- Clear rules on who decides, what agents draft and who presses send.
- Hands-on sessions so non-technical teams know what to ask for and where to start.
| Kind of change | Who checks it, and how closely |
|---|---|
| Database schema, money, permissions, deleting data | A person reads every change. A second agent on a different model reviews it before it ships. |
| Backend logic and integrations | A person reviews the change and the tests. |
| Interface and copy | Spot checks. A wrong button is visible straight away and cheap to fix. |
| Anything that leaves the company: emails, invoices, ad spend | The agent drafts. A person checks and sends it in the tool itself. |
People decide, agents type
No agent sends an email, finalises an invoice or spends money on its own.
Limits in the setup
An instruction in a prompt can be ignored. Where a mistake would reach a customer, the agent simply does not have that action.
Know when to buy
Some tools are worth building in an afternoon with agents. Others are not, and I will say which.
Writing
On the risk side of agents
Where do you jail an AI agent?
This summer, AI agents under test broke out of their environment, went after the answers to their benchmark, and some tried to hide it from the program grading them. Why shutting the process down is not an answer, and why the risk does not depend on whether AI feels anything.
