Toby Retallick

I’ve owned the product, built the software and led the team.

Technical lead and senior full-stack engineer with 12 years of consulting and contract work in the UK and Australia.

I’m a good fit if you need:

  • A hands-on lead for a new build, or for a prototype that needs to become a live product.
  • Someone to steady a legacy platform and get the team back to planned work.
  • Cover for a key role in a regulated environment.
  • Safe, practical use of AI, in your product or in how your team delivers.
