Erik Stenman has been programming for fun since 1980, and for profit since 1989 when he started his first company. He received his Master of Science in Computer Science in 1996 from Uppsala University. Erik was one of the driving forces behind the the High Performance Erlang project (HiPE) from the start in 1996 until he successfully defended his Ph.D dissertation against opponent Simon Peyton-Jones. During his post-doc as a project manager in Martin Odersky's Scala group he helped bringing the project to a successful release of Scala 1.0. Before joining Kreditor he worked at Virtutech with low-level optimizations of Virtutech Simics.

Currently as CTO at Kreditor Erik is responsible for the development and operation of "Kreditor Online", a system providing creative payment solutions to Internet shops.




Kreditor provides creative payment solutions to Internet shops. We are basically a bank specializing on E-commerce, providing secure transactions between consumers and on-line stores.

Our business model puts high demands on our system in terms of availability, throughput and security. At the same time we constantly introduce new features, staying ahead of or competition by doing very rapid development and having an extremely short time to market.

In this talk I will present our business model, our system architecture and our development method. I will also tell you how we have taken advantage of Erlang in order to, in just three years, become Sweden's leading provider of invoicing and installment plans over the Internet.
