RGJ began in high fashion with Barbie dresses as a child and became an established haute couture designer in his twenties. As part of his formal training, he was mentored by Christopher Morris of the London Fashion Institute from 1976 to 77 where he became a master at pattern cutting and grading. Later when he returned home and expanded into art and theatre circles his talent won him the Cacique Award for best costume design for La Cage Aux Folles (1999). 

In addition to haute couture and costume design, RGJ has worked on a variety of performance projects including the 1995 Jean Michel Jarre Concert for Tolerance in Paris, France. He has also taught costume design and construction at the Cleveland Museum of Art and Design and made costumes for their annual Parade de Circle for four (4) years. Nearer to home he was involved with the 1999 Miss Universe Pageant in Trinidad, the closing ceremony of the 2007 ICC Cricket World Cup in Barbados, the design and production of the 2007 Machel Montano show in Madison Square Garden, and collaboration with Peter Minshall on many other projects (see below).

The carnival exploits of this master of artistic design and prototype engineering read like a master class in creativity and are a testament to his ability to transition effortlessly and expertly from prototype to production. RGJ created all the prototypes including the manufacture and production of all of the costumes for the following bands as well as the production, development, and manufacture of the King and Queen portrayals indicated below:
