I build software. There’s plenty to figure out.

Sven Petroll

I'm Sven, a senior software engineer. I want to understand why something works and where it breaks. I’m open to a permanent role on an engineering team.

Work

My work combines investigation with implementation. I use measurements, code and conversations with the people involved to understand a problem, then work through the system to find a solution that holds up in practice.

Product development at Digitec Galaxus

Rethinking product filters ↗

Product filters above the results, explicit state and a dedicated mobile interaction model. My contribution included state management, routing and navigation.

Business software at Softtech GmbH

Signed licenses instead of dongles ↗

Software licensing through signatures, offline use and support tools. A technical decision that also changed the processes around the software.

Performance at Digitec Galaxus

Making web performance actionable ↗

Turning Core Web Vitals into engineering work. I worked on measurement and analysis with Datadog and BigQuery and supported teams through workshops and a Web Performance Guild.
