Обо мне

Разработчик/администратор/devops линукс. Хобби выросло в профессию.

С большим интересом и удовольствием берусь за большие и сложные новые проекты.

В свободное от работы время занимаюсь развитием своего дистрибутива, люблю дайвинг, периодически путешествую по разным странам.

Project Lead / Main developer
Январь 2009 — По настоящее время (11 лет и 7 месяцев)

The distribution was initially based on Slackware 13.37.

Today we reworked mostly everything in a newer way, but the ancestor was Slackware.

I'm the leader of the project, I manage the work of a small group of enthusiasts (designer, programmer, user/tester, admins) and maintain the whole distribution (about 2000-2500 packages). 

Today we support a lot of common used software including server applications and desktop environments. Also we offer a very simple to way how to build anything in a build system inspired by ports in BSD.

What was done:

- We are a mostly bleeding edge distribution focusing on new administration methods and new standards

- self-written package manager (alpha versions) with dynamic and automatic dependency detection (binary, perl, python2, python3)

- about 30% of performance boost for any type of server highly loaded production environments. (kernel)

- parts of the system over 1 year without any incident in production

- Middle-stage deployment in progress, heading to release.

We provide application development, technical consulting and 24x7 support services to clients from UK, Europe and USA.
