Ya know on second thought, it's so unbelievable that he did this whole thing that I wouldn't be surprised if someone reading his resume thought he was bullshitting.
Gamers playing this game have all kinds of tricks to try to bypass the load screen itself because it takes a long time to go through it but the game by design forces you to look at the load screen multiple times just to do one task. One way that I remember was to play in a Solo session that way you don't have to load every time you come out of multiplayer. They even make a GTA online software tool that blocks GTA on the firewall at very specific intervals to force an online session in order to speed up load times.
There should be such tricks for Codemasters' games specifically and PS1/PSP/Vita games in general. All those intro screens and warnings are absolute bullshit, just publishers spitting in gamers' faces.
