Pasi, Development Manager

I have worked with some of my colleagues since 1995 when I started as a trainee at my previous employer. At Good Sign I've been since the beginning. I'm basically a developer with the emphasis on the database layer, but there is also a lot of other things to do. For example, managing databases, installing new servers, upgrading old ones, helping to fix and debug customer support cases, managing our internal version control, reporting and ticketing systems etc. At a company this size there is always the option to either focus completely on your primary task or to branch out into different areas. I especially like trying out new software or components that we might use in our products.

I'm currently working part-time. I started it in 2000 when I went to university and when I graduated, we then had our first kid. My wife and I took turns taking care of him every other day. And while he's already in school we now have the same arrangement with our younger child. I don't have much spare time, but whenever I can, I like to jog to work. It's a great way to combine exercise into your working day.


Ossi, Support & Development Analyst

I have worked at Good Sign for 5 years now. My main task is the development of our customer self-service portal and partner service portal solutions. I am looking after the dynamics of the tasks performed and the efficiency of the user experience. I can take my technical versatility into use also within customer support analysis and being involved in database management.

My educational background is a double degree from Helsinki Business College and Upper Secondary School. During my studies, I did my 6 month internship at JAS Partners where I worked as a software tester.

I am a flexible employee. It suites me well to work at any hour of the day. Good Sign is a relaxed and flexible workplace where you can always find suitable and challenging tasks matching your competences. In my free time I like to go to the gym, play with my two cats and of course hang out on a computer.
