About me

a picture of me

I enjoy crafting elegant (web) solutions for complex problems. The times I enjoyed the most is when others said something was to hard and could not be done and I proved them wrong.
You can find me on various meetups each month and time and money permitting on conferences.

I have more than a decade experience creating web applications with tools like PHP, Javascript and MySql. Most recently I've built Digi-lijstje using PHP 7.2, Symfony 3.4, Phpunit, Cordova and React. Applying best practices while staying pragmatic. To keep the personal data secure I applied encryption with a combination of asymetric and symetric encryption using libsodium.

Before starting freelancing I was Lead Software Engineer at Webpower where I was tasked with modernizing of both the codebase and development practices. Introducing automated testing, applying DDD, code reviews, using VCS first using SVN and later GIT.
Using Docker and Node.js designed and created a scalable high available solution for sending billions of emails each year.
With DDD methods created a responsive collaborative email builder using React, Node.js and websockets, using CQRS and Event Sourcing. Using event sourcing for this project enabled us to easily implement version control and collaboration while making the codebase also easier to work with.

I studied to be a system/network administrator and while working as one I really enjoyed automating as much as possible. I've always really enjoyed logic and programming and it seems to come natural to me. However I still very much like system administration especially since DevOps became mainstream as that more or less was my introduction to programming altough the acronym was not invented yet.
