Juha YrjöläProject manager
Juha joined the city in 2013 as the first Code Fellow. He laments the fact that his time is spent more and more in meetings and talking in people languages instead of Python.
In his free time, Juha enjoys soy lattes, meditation, yoga, and generally rocking it.

Timo TuominenSoftware developer
Timo joined the City of Helsinki as a code fellow in 2014. Previously, he had been an open data hacker in the public library sector. Currently, a lot of his work revolves around managing the complexity of user interface implementation inside the web browser, but he considers himself a generalist and enjoys working at different levels of software projects.
In his spare time, Timo provides testing, support, and training data for an autonomous learning organism whose development process typically lasts multiple decades. He occasionally (rarely) enjoys the odd agave tequilana based beverage and is known to have played the guitar on several occasions.
Riku OjaCode Fellow
Riku joined the team as a brand new code fellow in 2015. His background is in computational physics and urban activism, and coding for the city has allowed him to (sort of) combine the seemingly disparate fields of interest.
In his free time, Riku loves tea, board games, cycling, parkour, friends, city planning, and squirrels, in no particular order.
Jussi ArpalahtiCode Fellow
When not creating with one device or another, Jussi goes forest biking or plays Ultimate, does copious amounts of reading - sadly more serious stuff than sci-fi these days - or fights with Internet to show him anything interesting.
