Since 2017, I have developed senderismocolombia.com, a web platform that streamlines registration, payment verification, and route assignment for hiking events in Colombia. The platform not only enables users to manage their activities independently but also supports the National Hikers’ Meeting of Colombia, an event with 2000 participants annually. Additionally, it manages regional events with around 500 participants. I have adapted the site based on user feedback, especially from older adults, to ensure accessibility and usability.
