Through applying to the Batsford prize i encountered this online website which allows you to apply to relevant competitions to your subject and also upload an online portfolio which anyone can access (including employers). Despite having a professional instagram and a linked in account i felt this was another very professional way to present my work to any potential employers. Whenever i get a chance between my uni work and job applications, i add another project to my portfolio to demonstrate my range of skills and apply to more competitions.
