Overview
During my few years at Solinor developing, teaching, coaching, leading by example, even managing a team for a while in order to best serve this goal, the company has grown from about half a dozen people serving a single customer reactively to one of around thirty people, several customers, determination, and an excellent reputation. It is a joint achievement of us all, but it was also my vision as I arrived. I yearn to repeat this success.
Through hobbies since 1983, work since 1989, studies since 1993, and running two tiny companies 1998-2004 I have learned and practised most aspects of software and systems development.
I steer toward purposeful, well organised work for small, empowered teams able to exceed expectations. I prefer to reduce complexity where possible and rely on empirism otherwise. My life is about continuous improvement at all levels.
I am drawn to quality and thrive in intelligent company. I find it rewarding to listen to and understand everyone. I am a natural leader, not a manager. I am well respected among my peers.
I think most highly of companies able to treat all their stakeholders as blessings.
Goals

Obligatory Acronym Listing
Past success is no metric for future. Neither do already acquired skills determine what people may be able to achieve, but I guess plainly skipping this part would cause anxiety for some, so here goes:
- I have years of excellent work experience with at least Perl (1997-), Java (1998-), Javascript (1998-), Python (2003-), C++ (2007), C (2002), C# (2007), PL/SQL (1998-), shell scripts (1997-), PHP (2005-). Scala and Ruby I've tried out a bit and would love any excuse to work with them.
- I understand and work happily with C++ templates (including STL), macros and multiple inheritance as well as frameworks based on those.
- I have some experience on J2EE but have mostly been able to avoid it. SOA is best with REST.
- I know UML coarsely, preferring to draw diagrams mainly intuitively.
- I have implemented some GUIs with XHTML, CSS, AJAX and WML as well as wxWidgets. I developed asynchronous web page updates (with hidden frames) before the term AJAX was even coined.
- I teach and use myself continuous, fully automated testing and deployment.
- Requirements I figure out best with user stories, use cases and/or given-when-then's tightly together with customers.
- I like to actually calculate resource consumption and limits of the systems I develop, and verify my calculations with tests - whenever we have the time for it.
- I define architecture and design on demand only.
- 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, dog, 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.
