Software Development and Automation Generalist

Contact Information

Overview

Lifelong programming and automation enthusiast with common sense always seeking more purposeful ways of working. Over time gathered experience from embedded to enterprise, self-employment to international corporations, but mostly from web-related work in small, ingenious companies.

Goals

I want to be Linus Torvalds instead of Linus Torvalds - in other words, I seek to eventually give something delightful back to the world at large; probably via automation.
I hope to deliver long-lasting, deeply satisfying solutions, and spread related abilities around me.
I yearn to learn new areas of expertise and understanding through cooperation with enthusiastic professionals. User experience could be next.

I like to do user stories, use cases and/or given-when-then's tightly together with customers.
I would love to actually calculate resource consumption and limits of the systems I develop.
I define architecture and design on demand only. SOA is best with REST.
I do possess very concrete understanding of data structures, algorithms, patterns as well as machinery underneath it all, analysis and the scientific method.

Family and Hobbies

I live happily at Malmi, Helsinki with my wife, dogs, car, 42" TV and three sons. I have sometimes been active in student, citizen, nordic larp, professional and neighbourial organisations. I compose, write lyrics for, and play rock music, read and write, but mostly play with my kids and enjoy vegetarian foods. Nowadays I like making small electronic gadgets and designing 3D printable objects. Occasionally I write some free software or design a board game.
