Zadier Castrellón

Dynamic and responsible freelancer, with experience in sales, customer service and commercial support. Focused on delivering fast results and continuous learning.
I stand out for my initiative, proactivity and good communication, which allows me to easily connect with clients and understand their needs.
I use digital tools such as Microsoft Excel and Canva to organize information, create visual content and optimize processes.
I am looking for freelance or part-time projects, where I can add value immediately and grow professionally while continuing my university studies.
