I work on mods for Serious Sam Classic: The Second Encounter for the most part (and sometimes The First Encounter too).
Check my GitHub to see all of my public projects in development (hell).
I don't have any contact information. If you're having a problem with a project of mine or have questions about it, leave a comment on the project page or create an issue in the project's repository, whichever one is more suitable. I don't do technical support for Serious Engine 1 and I won't write any code for you, nor help you with other projects in any capacity.
Mods for classic Serious Sam games (primarily The Second Encounter v1.07).
Maps for classic Serious Sam games (primarily The Second Encounter v1.07).
Other content related to Serious Sam games that isn't custom maps or mods. Tools, assets etc.
