Building software that people enjoy using is what gets me going. With over 12 years experience I've delivered successful products for the Telecoms, Retail, Publishing, Energy and Charity sectors. I've led teams to build a wide variety of projects including realtime social platforms and project management tools, business Intelligence tools, custom content management systems, online stores and browser extensions. Since 2004 I've been an agile practitioner, whether it's Scrum or Kanban, Lean, BDD, outside-in, pair-programming, you name it, I've been doing it for years. I've usually led from the front but I’m comfortable working in many different styles and value project consistency over personal preferences so am equally comfortable working alone or slotting into an existing team.
