Jankees van Woezik

Code cracking, mathematics loving developer.

I am Jankees van Woezik, something that you probably already guessed from the url of this website. I am an experienced programmer with a love for writing clean, useful, tested and reusable software. This is my personal website.

I have been working as a freelance developer since 2008 but have been making websites since ‘98. I was 14 at the time that I made my first website and it includes #ff0000 as a background colour (fun fact: it’s still online). This last decade I had the luck to work on great projects for; V&A, NRC, Anne Frank huis, Dom Perignon, KPN & Blond Amsterdam. I’ve also been hired by companies as a part of their team to work on projects for; Ultimaker, Achtung!, Zilverline, Your Majesty and Random Studio. The full list of projects I’ve worked on is stated below, I must warn you it is long but so are ten years.

Next to my freelancing, I also created some products; two Mac applications and a few web applications. The most prominent one is Stekker smart charging tool that launched in 2019 and which I'm currently still working on full time. This also means that I'm not available for freelance development work.

Back to the reason why you are probably scrolling through this website right now; my line of work. I am a full stack developer. Currently, I mostly do back-end work with Ruby. However I’ve been working on both back-end as well as front-end development jobs over the last decade.
