Since
2021

I write mobile apps. Flutter for 2.3 years at atFirstSite, then native Android (Kotlin, Jetpack Compose) for 2 years at Deloitte on three retail e-commerce apps, where I now also run web accessibility assessments. I build the feature, wire the analytics, and test it. On my own time I build Healpen, a journaling app, Peakward, a running app, and Noima, a spaced repetition app, all in Flutter. I maintain famon, a Firebase Analytics CLI on pub.dev. I am finishing a B.S. in Informatics Engineering at the Hellenic Mediterranean University. In 2023 my team won the ATHENA hackathon with a sustainable fashion app built in 48 hours.
