Hi, I develop for the web

  • Web development

    I develop for the web from front to back. My main expertise lies in front-end developent. I'm a skilled HTML, CSS and Javascript developer. I am also capable of developing on the server side, using Node.js, PHP or C# ASP.NET. Last but not least I like to be involved in the design/UX process of a web application.

  • Javascript

    I'm a Javascript enthusiast. It's the language that got me hooked on programming and is very important for the web. From designing a Javascript application architecture to implementing a new framework like React or Angular, I can do it. I'm a big advocate of functional programming in Javascript and in love with ReactiveX.

  • Learn

    I find constantly learning new things manditory for being a successful developer. If I need to learn some framework, language or method, I am eager and capable to learn it fast. This makes me flexible in finding new solutions.
