I have 25 years of development and software architecture experience in .NET technologies. I worked at Microsoft for 10 years, where I ran the UK performance and scalability labs and trained and consulted for many companies. For the past 5 years, I have been working freelance, mostly for investment banks in the City of London. I am currently the highest rated contribute to the Reactive Extensions tag on Stack Overflow. I routinely speak at user groups and mentor developers on .NET technology.
