Paul Scanlon shares his journey from digital advertising to tech in the "Voices of Gatsby" series, highlighting the importance of a structured approach to projects, which he metaphorically describes as "seeing the Lighthouse." With a career spanning over sixteen years, he began in digital advertising, earning accolades like a BAFTA for digital creativity, before transitioning to building React applications. Drawing from his diverse experiences, Scanlon emphasizes the value of planning and vision, arguing that projects should start with a clear end goal before diving into coding. He illustrates this through his creation of "BumHub" for Gatsby's Silly Site Challenge, showcasing how his advertising background informed his tech projects. Despite the often chaotic nature of tech projects, Scanlon advocates for maintaining process and structure, likening it to the "measure twice, cut once" mantra instilled by his family. He encourages others to adopt this mindset to enhance their own project outcomes.
