Personal Details

Robbie Coomber

Professional Profile

I was taken to the London Science Museum too many times as a child and developed a fascination for pressing buttons. This turned into a love of technology and a eventually a CS degree. I’m now building things that are indistinguishable from magic.

I’m currently looking for freelance work or exciting start-ups to be involved in.

2009 July - 2009 September


Software Intern

Off the back of my second year group project win with SolidWorks as the corporate sponsor, I was invite to join their research department to explore how touch interfaces could be used in CAD. This was in 2009 so before the iPad even existed!

We were given a Microsoft Surface (not the tablet, the coffee table, now known as PixelSense) and created several apps showcasing different use cases.

Core technologies used: C#, Windows, WPF, XNA.


2007 - 2011

University of Cambridge

Computer Science

My final year solo project was to create an algorithm for an efficient motion search (used in videos codecs) to run on a GPU. The implementation was in CUDA and C.

My second year group project was to create a multi-user design program that uses a DiamondTouch table as input. A team of judges invited from industry chose my group’s project as the winner, based on a live technical demo and a short presentation, which won us a cash prize from IBM. This victory led to my internship with SolidWorks.

I had intermittent problems with RSI during my degree, which forced me to take a year out between my second and third years of study. This is included here because otherwise the dates are confusing (4 years for a 3 year course, with an internship at Kynesim in Spring during what would have been exam term).

I was unable to take my final exams due to RSI, but the university granted me my degree due to the quality of my work up to that point. This is called DDH or Deemed to have Deserved Honours (longer explanation).


Andrew McCafferty

Senior Software Engineer at The App Business

Robbie is an excellent developer, one of the best I've ever worked with!

Seemingly able to turn his hand to any framework, whether it's a complicated Docker setup, or setting up a robust and maintainable React application (he was instrumental in the great success of the sophisticated front-end of the application we worked on together), he approaches everything with the highest of standards.

He takes pleasure in sharing his knowledge with others, which makes him a great asset to any team he works with.

Robert Desmond

CTO at StoryTerrace

Robbie Coomber is the best developer I’ve worked with. He is extremely thoughtful and forward-thinking, always looking to solve problems before they arise using the most efficient tools out there. I hope I can work with him again soon!

I teach web development skills to female University students.

In May 2017 I was delighted to be voted Instructor of the Month by my former students.
