HCI: Creating seamless user experiences
Human-computer interaction (HCI) is a multidisciplinary field focused on designing user-centred interactive computing systems. It bridges the gap between technology and human needs, ensuring software, websites, and applications are intuitive, enjoyable, and efficient to use. For businesses, investing in HCI expertise translates to increased user satisfaction, improved product adoption, and ultimately, a stronger bottom line.

Look for evidence of user research methodologies, prototyping skills, and usability testing experience. Excellent communication and collaboration skills are also crucial, as HCI freelancers often work closely with development teams and stakeholders.
