Hi, my name is Mark Coenraads and my hobby is building websites and developing web applications. I've been in this hobby for several years now and I've learned programming myself using online tutorials and forums. The programming languages I use are: "HTML5, CSS3, Javascript and some PHP". I use the name cosmos77 because my father used to use the name cosmos as a brand name. This website contains a number of websites and web applications that I have developed myself.
