About Karsten Silz
I have worked as a full-stack Java developer for 23 years in Europe and the US. In 2004, I co-founded a software product start-up in the U.S. I led product development for 13 years and left after the company was sold successfully. Since 2017, I have been a contractor in Germany and the UK (Spring Boot, Angular, Flutter). I co-founded the SaaS start-up “Your Home in Good Hands” as CTO in 2020.
I grew up in East Germany, behind the Iron Curtain. I wrote my first BASIC program on a Sinclair Spectrum ZX81 in 1984 and never looked back. I got a Master’s degree in Computer science from the Dresden University of Technology in 1996.
My first job after college was with American Management Systems. From 1996 through 2001, I worked in Sweden, The Netherlands, Berlin, and Great Britain. My next job was at Mundwerk, a start-up in Berlin, from 2001 to 2002. I then became a contractor in 2003.
My biggest adventure so far began in 2004 — Seldon Systems, a software product start-up near Atlanta, Georgia, USA. For 12 years, I was the VP of Engineering and led the development of a monitoring software product. My co-founder and I successfully sold that company in 2016.
From 2017 to 2019, I was a Java contract developer in Stuttgart, Germany. I followed my wife to Milton Keynes, UK, in July 2019.
In January 2020, I embarked on a new adventure - “Your Home in Good Hands”, a SaaS start-up for cat-sitters in the UK. I’m the CTO & sole developer for the Java back-end, a web front-end, and native mobile apps.
In my free quarterly newsletter, I recommend the tools you need to build Java applications today by observing what all Java developers do. Check it out here:
The number of developer ads is down in 2023 by about 25%. Spring Boot is back to 500% of Jakarta EE job ads, while Quarkus and Micronaut rose again after a four-month decline. The monthly number of Stack Overflow questions is down 42% since ChatGPT appeared.
