Hi, I'm Clemens, a computer science student at ETH Zurich, currently on exchange at Princeton University. Welcome.
You can reach me at csageder (at) ethz (dot) ch.
I am pursuing a B.Sc. in Computer Science at ETH Zurich with a GPA of 5.65 / 6.0 (top 5%), where I am also semester spokesperson, representing 600+ students.
At Princeton, I currently work on AI agents research under Prof. Karthik Narasimhan.
Before that, I interned at Stripe in Dublin. I built a unified refunds pipeline for six direct debit methods, migrating ~$600M/year in refunds, and created automated penny-testing agents and implemented Adaptive Pricing for ACH and ACSS.
At ETH, I spent a few months as a research assistant in the Distributed Computing Group (Prof. Roger Wattenhofer), developing ML models for extracting vascular networks from 3D mouse-brain microscopy scans.
I was also a teaching assistant for Linear Algebra at the ETH Zurich Department of Mathematics.
While still in high school, I spent two summers as a software engineering intern at Dynatrace, where I led the development of transpilers converting Splunk Query Language (SPL) and Prometheus Query Language (PromQL) to Dynatrace Query Language (DQL).
Also during high school, I was dual-enrolled at Johannes Kepler University, completing computer science coursework with a GPA of 1.06 / 1.0 (top 1%).
