What it was
My first shipped software, built while I was a student. New students, guests and even staff at Wolaita Sodo University kept getting lost between the main campus and the technology campus, so I built an Android app that lists offices, dormitories, departments, the registrar and other services and guides the user to them from their current location. It covers both campuses. I built it as a native Android project, designed the screens myself and recorded a walkthrough video so people on campus could see what it did before installing it.
What I learned
Taking a project from an idea to something other people installed was the lesson. I learned that the data behind an app, every room and office name, needs maintaining as much as the code does, and that a mobile product is mostly design and testing rather than programming. It also gave me the confidence to take on the deep learning project the following year, and it is why the years sentence on this site starts in 2021.
