My girlfriend works as a teacher at a school that is part of a school affiliation. During the COVID-19 pandemic, students had to work from home, which put pressure on the IT infrastructure. To assist, I offered advice and developed a small web app to help teachers organize their homework and lessons. I did it for free but the app spread like fire around others schools. Some needed support, some needed new features. That's how I got started. After a few weeks I started to charge.
