Writing, talks, and research on distributed systems, engineering, and leadership.
A terrifyingly hilarious journey through the leadership traits that kill culture, drive away talent, and burn projects to the ground. Micromanagement? Check. Cryptic communication? Check. Taking credit while blaming others? Chef's kiss. You'll leave laughing, and maybe sweating, because you've either seen it or been it.
