History and Present

Hello! My name is Miki and I am a software developer. was founded in 2005 in Gdynia (Poland) with the focus on delivering software according to specific needs of its users - the market of platforms was not that developed yet and many of my clients needed a dedicated solution, as they could not find a ready-made solution in the market.

The secondary purpose behind the company's existence was to be able to deploy software I made for myself - I somehow thought that having a company name appear instead of author's name will make things more professional, and so I used it in the copyright notice of basically any software I had written since the early 2000s.

And now, two decades later, we are here. remains my business name in Turku (Finland) and is kept alive as a side gig to my full-time job. The primary purpose slightly eroded over time and now it is just my own software being released, with the hope of someone, some day, finding it useful.


Over the course of my professional career I have worked with hard-to-remember-how-many technologies and projects, ranging from mobile application written in Java ME, a distributed facility control system for Windows written in Delphi, a client-server application in Java and PostgreSQL, to a set of Ruby scripts to process documents.

In addition to the above, I am self-hosting pretty much everything I need (with the exception of source code) and thus gained a rough proficiency in maintaining an Ubuntu server with quite a few servers on it, including Open VPN, Dovecot, and Apache among others.
