Meet Team Dyalog

Meet the people who make it all happen – a few facts and a bit about each of us in our own words.

Joined Dyalog Ltd: May 2020

Stine (Kirstine) grew up around APL and her first encounter with many of Dyalog Ltd's customers was at the help desk whenever the user meetings were held in Denmark. Although her experience with APL is sadly lacking, her interest in management and accounting is being put to good use.

Technical Director (CTO)

Based in: Danish flag

Joined Dyalog Ltd: April 2005

Morten joined Dyalog Ltd after spending about 15 years building up ideas for technical direction as a user of Dyalog – 10 as an APL Consultant and 5 as the CTO of Adaytum Software, developing a "shrink-wrapped" product which used Dyalog as the core technology. Before that, he spent about 10 years learning, using and helping clients install and maintain SHARP APL at I.P.Sharp Associates.


Company Secretary

Gitte discovered APL in 1983. After graduating as a research biologist, she was offered 6 months of training in EDP (Electronic Data Processing). When exposed to APL she immediately fell in love and never looked back. Since then she has worked as an APL consultant, headed development and sales of commercial software based on APL and finally in 2005 ended up where she started, at an APL language vendor – but this time as the CEO.

Aarush, also known as sloorush or rush, joined Dyalog Ltd after completing his bachelor's degree in Computer Science, passionate to work on programming languages. When not working, he can be found travelling, trying to click a picture of something in the room, or looking at new ways of making his coffee taste different the next morning.


System Administrator

Based in: British flag

Joined Dyalog Ltd: September 2023

After graduating with a bachelor's degree in software engineering, Abs looked for a place to grow and put his software and IT skills to use – he found this when he joined Dyalog Ltd! Although he is new to the world of APL, he hopes to become familiar with the new squiggles as well as help to solve technical problems so that the rest of Team Dyalog can work efficiently.

Head of Language Design

Based in: Danish flag

Joined Dyalog Ltd: May 2015

Adám prides himself on having got APL with the breast-milk, as he attended his first APL conference at the age of one. He is adamant in many of his convictions, including that APL is by far the world's most superior programming language, and the only one worthy of being used day-to-day. His work is mainly in the development and maintenance of APL tools.


Chief Operations Officer

Based in: British flag

Joined Dyalog Ltd: July 1987

Andy has spent most of his working life in support, supporting APL but also UNIX systems and high-end hardware. He is less the theorist and more the pragmatist. He is responsible for Dyalog Ltd's internal systems as well being involved with the development and QA processes.

Bjørn has been making add-ons for APL since the start of the '90s, first at Insight Systems ApS, then at Adaytum Software and now at Dyalog Ltd. He concentrates on moving things that are hard to do in APL or that have poor execution speeds into C so that they are callable from APL. The best known examples of these are SQAPL and Conga.

APL Tools Architect

Based in: American flag

Joined Dyalog Ltd: March 2011

Brian learned APL in 1975 when as a freshman in high school he discovered that the typewriter that knew how to play football was actually a computer terminal hooked up to the University of Rochester's APL timesharing system. Brian has developed APL applications across a variety of industries including financial planning, manufacturing control, legislative tracking, full text databases and risk assessment. Brian has twice been recognised by the ACM's SigAPL for innovative APL development. "I'm very blessed to be a part of the Dyalog team; building tools that make it easier for our customers to do their jobs."


Documentation Manager

I.T. Manager

Based in: British flag

Joined Dyalog Ltd: May 2007

Michael got in contact with APL in the last century through his first job as Production Planning Analyst supporting an APL application. The speed in which development implemented any changes made him curious about that strange language – and the rest is history. In his rare moments away from the computer, Michael likes to spend time with his family, enjoys travelling, music and boring computer-games as well as board-games. He also loves British humour (claims to sometimes even understand it!), English tea and Danish cookies. Sometimes he sleeps.


Marketing Specialist

Based in: British flag

Joined Dyalog Ltd: September 2023

Mike's experience prior to joining Dyalog Ltd included working with international organisations and managing a wide range of clients, from local businesses to major brands.


Based in: Greek flag

Joined Dyalog Ltd: September 1977

Pete had the amazing luck to be a member of the team, alongside John Scholes and Pauline Brand, that acquired what was then Dyadic Systems in 1990 and guided it through the formative years of Dyalog Ltd. His only truly wise business decision was to hand over the reins in 2005 and he now luxuriates in partial retirement on the Greek island of Alonissos. When not writing Dyalog documentation he struggles to learn to speak Greek and to play the bouzouki. He hopes one day to become semi-competent at both.

Joined Dyalog Ltd: July 2022

Peter joined Dyalog Ltd after finishing his bachelor's degree in computer science from Aalborg University in 2022. He first heard about APL in 2021, and started playing around with Dyalog, which seemed refreshingly different from other programming languages. He spends his time improving the interpreter as much as possible, and hope that other young people discover APL as well.

Rich discovered APL shortly after discovering Dyalog Ltd's headquarters on his own doorstep in Bramley. With a degree in physics and interest in computing, he was surprised to have not heard of it before. He hopes to introduce many more people to APL so that fewer future experts have to be deprived of APL's prowess in conveying problem solutions to computation engines. He's wondering when is an appropriate time to tell them about his own personal duck collection.


Development Manager

Based in: British flag

Joined Dyalog Ltd: June 2008

Richard joined Dyalog Ltd with a degree in computer science from City, University of London, and 20 years' experience of compiler development and language design. He develops and maintains the Dyalog interpreter and oversees its overall development.

Rodrigo stumbled on APL by accident in early 2020, as he posted programming challenges in an online code golf community. APL's simplicity, brevity, and affinity with mathematics got him hooked. Now Rodrigo is exercising his passions for teaching, programming, and mathematics, in an attempt to get many new people interested in APL.

Joined Dyalog Ltd: July 2020

Ron first encountered APL/360 in 1969, and then used it to teach Computer Science courses in the high schools of Hampton, Virginia. Over the years he was involved with several different APL implementation projects before doing a few non-APL things with Microsoft, Amazon, and an Internet Television company. During all those ventures APL has served him well as a tool for thought.

Silas found APL and Dyalog Ltd before his recent graduation and was very happy finding a job where his computer interests bring in a salary. When not noodling making computer things, he enjoys finding a quiet nook to read a good book full of magic and mystery – perhaps even with some tea!

Stefan discovered APL through the Advent of Code challenges, an annual Christmas-themed programming competition, but never thought that this chance encounter would lead to a career in APL. He's a Mac fanatic but does his computing on the command-line. Stefan is a keen skier and a proud MAMIL.

Vince enjoys helping customers. He is mainly a C programmer, but loves having Dyalog on his desktop as it's a really useful tool to do a quick calculation or write a quick program in. His computer runs Windows, and he uses command-line shells as well as the GUI.
