Summary

I'm a software and web developer with 15 years industry experience.

My expertise spans the spectrum of development, from front-end JavaScript & HTML5, server-side web development in PHP, networking and audio-video technologies in Java, C++ and C#, down to real-time embedded C.

I take pride in applying my eye for detail to architecture, debugging and documentation, and I have a conscientious approach to creating software which fulfils the needs of the end-user.

I enjoy taking central roles in teams with agile workflows, and I also gain satisfaction from working with people in non-engineering positions, using my excellent communication skills to bridge the technical – non-technical gap.
