Swizec Teller is a software engineering educator and writer who shares practical lessons drawn from more than 20 years of building production software. His experience spans side projects, small businesses, and high-growth startups, including both successful and unsuccessful ventures. Through his website, Swizec offers articles, essays, books, and a newsletter focused on the realities of modern software engineering and the skills that are often learned only through hands-on work.
