About
I'm Marvin Tseng, a lead iOS developer at PostFinance and a part-time MSc Informatics student at the University of Zurich. I'm based in Zurich, Switzerland.
At PostFinance, I work on modular architecture and the core banking app used by millions of people in Switzerland. Before that, I was at Digitec Galaxus, where I helped grow the iOS app's rating from 2.0 to 4.8 stars. At UZH, I'm exploring areas like software architecture, program analysis, human-computer interaction, and AI.
Outside of work and school, I'm into endurance sports — running and cycling keep me balanced. I care about craft, quality, and what it means to build things that last.
