About me

Developing software has been my passion for over 20 years. I take pride in providing well structured, well tested and properly documented code and strive to write code that any developer can effortlessly pick up.

I especially enjoy working in teams with a consistent focus on self-improvement and delivering business value. I’m a highly critical individual and I’m not afraid to criticize both my own and my team’s performance, suggest improvements and then act upon them; one of the reasons why I became a Certified Scrum Master in 2015. Thanks to my pragmatic approach and my strong background on the intersection of business & technology I’m well capable of providing practical solutions to challenges of a diverse nature.

Services I provide

Ship, ship, ship!

Strong focus on getting things done. I provide frequent updates during the development process, allowing for quicker feedback loops, higher flexibility & better quality.

Dedicated professional

Enthusiastic personality and exceptionally dedicated. I’m highly critical and always looking for ways to improve.

Team player

I thrive in team-based projects. I love being part of a team, whether it’s a multi-disciplinary or dedicated Android team, remote or on-site. I’ve been part of successful teams in both agile & more traditional environments.

Process optimization

Is your app publishing process tedious and cumbersome? Build process automization makes this a thing of the past, automating the whole process from build server through Play Store.

Code quality

I take pride in my code and use SonarQube^TM to validate and quantify the quality of my code. I follow best practice guidelines to allow for faster and more flexible development, without running the risk of having to rewrite your application in the future.

Automated testing

I take quality assurance very seriously. This is why both unit testing & integration practices are an integral part of my workflow.
