Behind the projects
Why I build these apps
Computers and games first caught my interest as a teenager, and that enthusiasm has stayed with me. Today I put that passion into my own apps and enjoy turning ideas into something other people can use.
For families and daycare centres in particular, I want to build things that are fun and make everyday life a little easier.
