Hi. I'm Matt Biggin
Developer

I'm a developer with 24 years of professional experience working on a broad spectrum of applications mainly in investment banking and financial services. I've spent the last 19 years working as a contractor at various investment banks around the City of London and Canary Wharf. I'm a huge fan of writing clean, well tested, reliable code. I take a great deal of pride in the quality of my work and I enjoy the challenge of working on large well established systems. I also offer freelance mentoring services so if you need a helping hand with your career then get in touch.
