a software professional and an enterpreneur
Since 2009 I've been working in Poplatek Oy, a card payment industry company I co-founded.
I was born in February 12, 1977, in Oulu, Finland, and I'm currently living in Espoo, in the capital region of Finland.
My main interest is software engineering: I enjoy writing high quality software with a variety of tools and programming languages. I've also worked in various management positions.
In addition, I've been lecturing two courses (a practical security course nicknamed "hacker course", and cryptography basics) in Aalto University, in 2003-2009.
I have multiple academic and standardization publications, see publications.
Amiga and PC demo scene work (using the name Silver Eagle) in demo groups The Silents, Pygmy Projects, Pulse.

Duktape is similar in spirit to Lua, but favors compactness and portability over speed as there are several very fast Ecmascript implementations already out there. Duktape has a combined reference counting and mark-and-sweep garbage collector with finalization support. As part of E5 compliance Duktape has, among other things, full regular expression and Unicode support. There is a C API for writing C/Duktape bindings.
