Stefan K.

Web-development and programming is my passion since more than 15 years, and I have been working as a freelancer for most of this time. In addition, I hold a diploma (equivalent to a master's degree) in Mechanical/Industrial Engineering and Business Administration. I like to write clean and efficient code and I know about potential security flaws. I have a strong analytic background and I am able to make solid concepts for software design. I can implement complex algorithms while focussing on efficiency. Lately, I enjoy to work with the latest technologies in the JavaScript/Node.js ecosystem (frontend and backend). Beyond that, I have solid knowledge in many more languages, technologies and frameworks, including PHP, MySQL, HTML, CSS, jQuery, HTTP, WebSockets, WordPress, Android/Java and Excel/VBA. You can find some of my work on GitHub (user skleeschulte) and might find it interesting to have a look at my Stack Overflow profile (user x-ray).
