Mapping since '99 eh? Do you have other work online with HL or other engines? Google didn't turn up anything... 
Since, you asked :
Back in the times, when the games was made by the fans for the fans, as a teen I bought the HL1 Disk, "Worldcraft" comes with it. I started mapping then, but my ideas was too much for the HL engine, Worldcarft and the comiplers, back then. I'm not the best and famous mapper in the world, but I had some good small maps for Half-Life, Opp. Force, Action HL, CS, TS and so.., when all was WON, not steam... For many important reasons, I didn't upload even a single map back then... Now, I decided to update/fix and finally publish this old stuff (models, prefabs, maps...), but I'm not an active mapper from a looooong time... I don't have much time now, so this process will take some time, so I will upload soon some fixed maps I made century ago...
VIVA OLD SCHOOL GAMES!!!
