👋 Who I Am

I'm an engineering leader and architect with 20+ years of experience designing systems, leading teams, and shipping products that scale. I specialise in API design and integration platforms, having worked across Fintech/Banking and Enterprise SaaS/Dev Tools.

I've led teams of 5–20 engineers, shipped products used by Fortune 500 companies, and built platforms that handle millions of API calls daily. I'm equally at home scoping a system on a whiteboard as I am reviewing a pull request or mentoring a junior engineer.


🔭 What I'm Known For

  • API & Integration Architecture — designing platforms that connect complex enterprise systems cleanly and reliably
  • 0→1 Product Building — taking ideas from napkin sketch to production-grade systems
  • Legacy Modernisation — untangling monoliths, de-risking migrations, and building a path forward
  • Scaling Engineering Teams — hiring, structuring, and growing teams that ship with confidence
  • Training & Workshops — hands-on sessions for engineers and teams on architecture, APIs, and modern tooling

🚀 Current Projects

What I'm actively building and maintaining:

Unmaintained:

  • 📲 SMS Gateway - Turns your Android phone into a simple SMS gateway.
  • 💻 Bash Menu - A simple bash list menu for directory switching
