Strategy.
Architecture.
Delivery.
I take enterprise AI from pilot to production. I answer the executive question, “is this safe and ready?”, then build it with their teams until they can run it.

How I apply AI in a client's business
Fix the process. Then add the agents.
Strategy, architecture, and delivery in six steps. Each one ends in something the client keeps.
- 1Strategy
Pick where AI pays first
You get: Use cases ranked by value and readiness, a build-or-buy call, and an executive owner
- 2Strategy
Map how the work really runs
You get: A process map with the costly exceptions marked, and the baseline to beat
- 3ArchitectureClose-up below
Decide step by step, system by system
You get: A target architecture and a decision log the client's architects can challenge
- 4Architecture
Set the guardrails and the platform
You get: Agent permissions, evaluations, and an audit trail, mapped to the client's rules
- 5Delivery
Prove one workflow in production
You get: A live workflow with its test suite and cost per transaction
- 6Delivery
Scale and hand over
You get: A reusable pattern, named owners, a runbook, and before-and-after numbers
Retire
2Stop doing it
- Re-key into core banking
- Email scans between teams
Rule
4Plain code
- Check the form
- Screen sanctions lists
- Open the account
- Send the welcome pack
Agent
4Needs judgement
- Read ID documents
- Chase what is missing
- Draft the risk summary
- Answer status questions
Human approval
2A person decides
- Approve high-risk customers
- Clear sanctions matches
Rules I hold to
- No build without a baseline
- No go-live without evaluations
- Cost per transaction tracked from the first slice
- Every agent has a named human owner
- Data stays where the client's rules say
I think in systems, and build what the business can run.
Every engagement starts with three questions. Who are we helping? What problem are we solving? What are we shipping this week to prove it?
Most firms split the executive advisor from the builder. I do both: I sit with the executives who sign off, then build with the team until they can run it without me.
