Sammanfattning

Tobias is a senior software developer and systems architect with an
extensive experience with building and maintaining large-scale systems with
high demands on availability and reliability.

A problem solver at heart, Tobias is happiest when faced with complex
problems. He is a firm believer in that most situations can be solved by truly
understanding the problem at hand and finding the appropriate way of
modelling the problem.

While Erlang is his go to language for development, his skills at analyzing
problems and finding solutions can be applied to most backend
development.

During his years at the High Performance Erlang (HiPE) research group at
Uppsala University he was the original developer of Dialyzer, a static analysis
tool for Erlang that now is an industry standard tool for finding bugs in
Erlang programs, and is included in the Erlang distribution.
