About me

Welcome to my portfolio. My name is Fred Bolder. I have programmed for more than 25 years (professional and hobby) in many different programming languages. For 12 years I was developing and testing software in Delphi and C# for nurse call systems in care homes and hospitals. Recently I attended a full-time web design course for one year. That is why I wanted this page to look like HTML and C#. You can click on the white bold text in the "code" to navigate.
I have many hobbies including programming, playing various musical instruments (piano, drums, recorder and more), singing (nowadays mostly Greek) and dancing (Ballroom, Latin and Greek dances). Related to my hobbies, I have written a lot of e-books. Writing these books and the manuals for the software, gave me a lot of experience in writing explanations in English.

Feel free to contact me by e-mail (fgh.bolder@gmail.com).

Projects

Software

Most of my software projects that are available online are programmed in C#. I made Transpose in JavaScript. For many projects I made a web page. Keep in mind that when I created these pages, I didn't know CSS yet and I typed all the HTML in a simple text editor. I have converted the pages to the new standard.
