I have gained valuable experience working as a Graphic Design assistant at your university, where you were involved in creating marketing materials for various events on campus, merchandise for different entities, and digital and physical signage. 

One of the key skills I've developed is working effectively within brand guidelines, which is essential in ensuring that all marketing materials and designs are consistent and aligned with the entity's image and messaging. Another skill I developed further, was communicating with a client and readjusting to their requests. The ability to adhere to brand guidelines & client needs will be useful in any future graphic design role I take on, as it helps to maintain brand identity and recognition.

Overall, my experience as a Graphic Design assistant and my freelance work have given me a wealth of practical experience in the field of graphic design. These skills and experiences will be valuable as I move forward in my career as a graphic designer.
