When he was young(er), Asher used to invent fictional languages for fantasy creatures. It should have been no surprise, then, that he found a love of designing and implementing programming languages when he began to experiment with computers. He studied computer science at the University of Warwick, where he discovered APL and was immediately hooked. After one cold email, two internships at Dyalog Ltd, and a master’s degree, Asher joined us officially as a developer.

Asher is working primarily on the interpreter, and is interested in both performance and correctness (two of our core values, so he fits in well!). Having implemented several small interpreters on his own, he is in awe at everything Dyalog APL can do, and eager to push it to even greater heights. He also loves to teach and present APL to new audiences, particularly when he can distill concepts into visuals and animations.

Outside work, Asher enjoys word games and board games. Once a keen chess player, he defended Dyalog Ltd’s honour against chess hustlers on the streets of New York whilst preparing for DYNA Fall 2025! He also goes running (when it is not too cold), and spends a lot of time on trains to visit his scattered circle of friends.
