Project history

I'm a software engineering professional having over 19 years of experience working in various software development projects in different positions. Projects have been mainly in the area of integration (EAI), telecommunications, automation (M2M, machine-to-machine) and logistics.

I like to work in data integration projects. I can take different roles in a project including Project Manager, SW Architect, Developer, Database Designer. I have coded in many different languages, but I prefer to work with Java or PHP if I can choose. I'm very familiar with different databases (e.g. PostgreSQL, MySQL, SQL Server, Oracle, Solid) and SQL language. I'm able to do database design and optimization work.

I enjoy working in the customer interface, providing technical solutions to improve customer's business. I have hands-on attitude and I'm not scared to develope something technically demanding that no one has done before. I have high interest in open source and Linux based solutions.

Currently I'm looking for permanent work in Tampere area and I'm also interested in international contractor based jobs especially in Germany, UK, Denmark, Norway, Sweden and Estonia.
Last years I've been working in international projects and my working language has been English. I can also speak some Swedish and German, however I have not used them years but I could refresh them pretty easily if needed.
