Beyond executive stuff, I was of course managing my own team of 3 developers, and was involved into development myself. We have made big impact distributing Open Source in Ukraine. Honestly, the service was the main store where people got distros quickly and easily.

The service was based on the OSCommerce engine, made of tons of spaghetti code. Yes, there was no good frameworks yet.

That’s why I’ve chosen Ruby on Rails later.
