I wrote a book on personal productivity called Pomodoro Technique Illustrated. It was initially published by Pragmatic Bookshelf in the U.S and it's now available in Japanese, Korean, Chinese, German, Russian, Swedish, and some other languages.
I give public courses in Monotasking and Regex. Let me know if you want any of these courses in-house at your company. They are easily adjusted in length and skill level to suit you.
I was invited to speak at Devoxx, AgileXX, Jfokus, ScanDev, GeeCON and many other major conferences in Europe and North America.
My role varies from developer and architect to Agile and Lean coach.
