Stefan Kruger

Developer

Joined Dyalog Ltd in May 2023

Role Summary

Stefan focuses on making Dyalog more attractive to new developers and application areas. He’s also the main advocate for the RIDE and Dyalog on macOS.

Biography

Stefan studied Computer Science at university, culminating in a PhD in Signal Processing and Computer Vision. He then worked long stints at Future Publishing during the maddest part of the mobile gold rush, and later at IBM, doing work in distributed databases. Stefan is always coding for fun, and eventually stumbled on APL – when he could not find any learning materials that appealed to his particular learning style, he decided to write his own (Learning APL ) and, in doing so, got to know various members of Team Dyalog online.

Stefan is a keen skier and cyclist.
