Uberdata was written by Blake Warner with information from PGMFI and stuff he figured out. It was originally hosted on PGMFI, but due to political / ideological differences, it is no longer. There is a HUGE ugly thread about it on honda-tech, and there are many boosted bins created with it on PGMFI. The PGMFI Wiki has the UberData FAQ and some other misc info.
But, as a simple answer to your question, there is not a webpage for the guy who made it. He's a good kid tho - if you use it and appreciate it send him some $$$ for his hard work.
