For over 10 years I've been helping founders & business owners build the technology powering their organisations. I've developed everything from simple marketing websites to entire SAAS platforms and everything in between.

With a background in computer science, I'm a problem solver at heart and love taking on complex and challenging projects. I'm great at quickly getting up to speed and breaking down tricky business requirements for industry-specific systems.

As a full-stack developer, I'm a one-stop-shop, able to take ideas from conception to completion, handling the entire process from start to finish.

So whether you're a non-technical founder building your first app or an established enterprise with an existing tech team, I'm ready to jump in and help you get your next big idea off the ground.

So why work with me?

With a background in computer science, my superpower is problem solving. I'm excellent at breaking down weird and wonderful ideas and figuring out how to get them built.

Having worked independently for years, I'm agile and able to move quickly. I've launched large internationaly publicised projects that had to work on day one so I understand the importance of reliability and performance.

Finally, I'm a great communicator and collaborator and understand that you don't always care about *how* it gets done, just that it gets done well and on time.
