Wolfram Kriesing

In 1997 I started to work in the IT industry. It has changed a lot since. I used to see specifications as something settled and the base for what I implement. Nowadays I know that even specifications need people to write them and that this can be fun. See ECMAScript specification, which is something that I am following since 1999.

While trying to keep up with the latest technologies and practises, I also practice and love TDD, incremental thinking and baby steps. I (co-)started and still run thinks like the JSCodeRetreat, JSCraftCamp, ES6Katas, TDDBin and a meetup called JavaScript the Language.

I started my carrier in the payment industry, freelanced a lot, and finally co-founded a small JavaScript consultancy called uxebu, which I helped run for 7 years. In May 2017 I joined HolidayCheck, and I am trying to share experience and knowledge with as many people inside and outside the company.
