Top SchoolJohn Hartnett is a Lead Software Engineer based in London with 8 years of experience designing and shipping full-stack web applications, currently architecting scalable AWS-powered systems that integrate React front-ends with Node.js back-ends.

Trained in both accounting (Penn State) and web development (NYCDA), he brings a rare mix of analytical rigor and creative problem-solving to engineering trade-offs. A lifelong learner and outside-the-box thinker, he favors pragmatic solutions and mentors lean teams to maintain high code quality and reliability. Passionate about unexplored approaches, he values letting the hands work through problems—a philosophy he cites from Carl Jung—so practical insight often leads his technical breakthroughs.
