about me

My name is Sebastian Pietrowski. I've finished Warsaw University as Master degree. I started my journey with Java 1.1 with Thread and JDBC programing in 1998 as I worked for merlin.pl. In 1999 I've passed Java Programer Certificate for Java 1.2, and was solution architect of merlin.pl infrastructure when we was moving from pl/sql to J2EE. It was great performance optimization with 10 times more req/sec than in requirements and 85 times faster as original solution.

Currently I work as Expert Software Development Java at F.Hoffmann-La Roche. The company was founded in 1896 and today, Roche employs over 80.000 people. After work I'm involved in activities related to Scala/Lift, Ruby/Rails/Merb, Python/Django. This is because I try to be pragmatic also I'm focused on application performance and tuning with success in my daily work.

My Yoda's motto: Do, or do not. There is no try.
