Hello, my name is Pirkka Esko. I am a freelancing, Helsinki-based software developer.

I've been working the internets professionally since 1997. Check the résumé on LinkedIn. Follow my sporadic tweets if you like.

I'm also the head tenant at Deck, a co-working space in Helsinki.

Below are some samples of my work.


Elisa Kotikisat

Finnish teleoperator Elisa wanted to create a marketing campaign based on a casual ice hockey game for smart phones. I was part of the initial concept design team at N2 Nolla and ultimately ended up doing 3D iPhone programming, real time audio analysis, scoring server and Facebook integration for the project. The game was eventually ported to Android by Enemy & Sons and to Windows Phone by Blend Media.

Silta-Valmennus coaches and helps hard-to-employ people to improve their ability to work and to function, and to find their place in society. Tähti is a life situation assessment software that Silta-Valmennus uses in their client work. I designed and implemented the software based on the original concept of Outcomes Star.

Social workers use Tähti together with their clients. I wanted the software to be friendly, down-to-earth and simple to use.
    When 2011
    Technologies Ruby on Rails, jQuery, SVG


Futudesign is the forum for architects operating in Finland. I was commissioned to create a new platform for the community based on initial design by Teemu Seppänen, the creator of the original Futudesign message board. The result was a fully real-time publishing/discussion platform.

Futudesign aims to recreate the traditional online community in a bold, visual style.

Music visualizer

The new visual identity of Sibelius Academy by 358 was based on the idea of visualizing of music. I programmed the utility for converting mp3 files to graphical elements that can be used in materials such as posters, brochures, calling cards and websites. The Echo Nest kindly provided a free API for analyzing sound data.

Martti Kalliala

Small portfolio website for my architect friend Martti Kalliala. Martti designed the basic layout and I took care of the rest.

The only technically challenging part in this project was to make the "subliminal" color change effect to work properly when jumping from page to page.
