I started programming at the age of 7, more than 30 years ago. I mainly do Javascript, C#, and Java, nowadays. I am interested in algorithms and node/edge graphs diagramming; I spent most of my academic and professional time working in the area of graph theory, graph drawing, and graph drawing software. I work for yWorks, however on Stackoverflow I do not represent my employer. My comments, thoughts, and posts are my own.
