Michael Sayman was searching "how to code" on Google while his parents saw their restaurant company crumble in the wake of the Great Recession. In less than a year, he had developed an iPhone application that was bringing in thousands of dollars each month, enough to support his family and remain in the country. Sayman was entirely self-taught and entered the workforce right out of high school at the age of seventeen, becoming Facebook's youngest employee ever while creating new features that impressed the company's creator Mark Zuckerberg and are now utilised by more than a half a billion people every day. Facebook's engagement rose across all demographics when Sayman pushed the company to create a rival to Snapchat's Stories. Millions of Gen Z and Millennials rushed to Facebook, and Snapchat's parent company saw its worth plummet by $1 billion as teen activity on Instagram and WhatsApp sharply increased. Sayman left the company three years later and joined Google. The inspiring tale of a young Latino who triumphed in the harsh world of Silicon Valley while still too young to drink and later became an inspiration to thousands of young people worldwide is told in App Kid. Sayman reveals the highs and lows, the triumphs and failures, of his incredible journey in this open and uplifting biography. Anyone who follows their own path should read this author's work since it is vital and encouraging.
