Joy of coding

We are organising for fun, not for profit.

The people behind Joy of Coding are an informal group, backed by a legal entity (the Devnology Foundation). We are organising this for fun, not for profit.


Felienne Hermans

I am assistant professor and speaker. I strive to make programming better and easier for non-programmers. I love functional programming and board games.



Arne Timmerman

Software engineer and community facilitator. I enjoy working in teams and crafting simple solutions that are fun to use. I’m a proud board member of Devnology and organizer of the Joy of Coding conference since the first edition in 2013.



Joy of Coding is organised by Stichting Devnology, a Dutch non-profit organisation registered with the Kamer van Koophandel (#17251880). Our VAT number is NL820757573B01.

van Amersfoorth

Martin van Amersfoorth

As do most of you, I enjoy coding - especially using a functional language, preferably Clojure. I’m married, with children, and outside of family life and coding I am coaching a soccer team of 10-year olds.



Cies Breijs

I’m a dad and a husband and a firm believer in mass-enlightenment. An open source enthousiast who adheres to a mostly vegan diet and prefers to keep the brain immersed in techno music.



Joy of Coding 2016 is the fourth in a series of conferences dedicated to software development. We are very grateful to everyone who has contributed to our conference in the previous editions: Freek Leemhuis, Anna Gos, Jacques Bouman, Mark van Straten, Daan van Berkel, Jettro Coenradie and Marc Lainez.


Rino Kadijk

I believe that technology isn’t the solution to every issue in the technology industry. I try to "automate everything" in my day job. In my spare time I contribute to the Axon CQRS framework.



Peter Hilton

I’m a software developer, writer, speaker, trainer, and musician. I love going to conferences and enjoyed Joy of Coding so much that I joined the team. I still have some time left for writing code, though.
