I am Serg Prasolov.
This is my personal site.

To be short, I am permanently looking for a good challenging job, as a Java Enterprise architect, a team leader or a senior developer. Last years I have been working on high load related projects and developing mostly backend, so please, do not consider me suitable for any roles in GUI or frontend development.
Other pages of the site are of no importance.

My resume follows below.
