Also working with

AI Startup Advisory

You built a real product using AI tools — without a technical co-founder. Now you need someone to tell you what you actually have, what it will cost to maintain, and how to make the right technical decisions as you grow.

  • Codebase audit explained in plain language
  • Architecture and scalability review
  • First engineering hire — who, when, and how to evaluate
  • Vendor and infrastructure risk assessment
  • Technical co-founder advisory

AI Engineering Workflows

For engineering teams adopting AI tools — from Copilot and Cursor to AI-assisted testing and code review. I help you capture the productivity gains without losing code quality, security, or team cohesion.

  • AI tool selection and team rollout
  • Code review standards for AI-generated output
  • Prompt engineering guidelines for engineering teams
  • Quality and security processes for AI-assisted codebases
  • Developer productivity and adoption metrics

Custom Software

Software built around your business, not the other way around.

Beyond consulting, I can build software to solve specific business problems that off-the-shelf tools can't address.

01

Business Process Automation

Zapier, Make, n8n, PowerAutomate — or fully custom.

02

System Integrations

Custom API development connecting your existing tools.

03

Industry-Specific Tools

Software shaped around your processes, not a generic template.

04

Legacy Modernisation

Rebuild or extend ageing systems without disrupting operations.
