a real world point of view
Nicolas Hernandez - sometimes credited as Nicholas Hernandez - was a senior 3D artist on most episodes of RTD-era Doctor Who. Though never credited as such, he was effectively the supervisor of the 3D/CGI department. He was likewise attached to the first two series of Torchwood.
Outside the Doctor Who universe, he has been a 3D artist, CGI supervisor and/or visual effects supervisor on some of the most CGI-heavy shows on British television in the early 21st century. He has contributed to Hex starring Christina Cole; Bonekickers; Merlin with Colin Morgan, Anthony Head and Richard Wilson; and Alice.
