Idea replies — I have human-centered design (HCD) experience for web and digital products and a few free hours a week

A disclaimer: An idea to differentiate yourself and I'm not sure that makes any sense! Here goes. Focus on how people in their 70s and 80s experience websites and apps. You could invite a few seniors to test digital products, observe where they struggle, and offer businesses practical ways to improve. My guessis you'd uncover things that younger designers and developers routinely overlook, and in the process, might carve a niche that is often overlooked.
