1 Katharine Graham: The Woman Who Took Down a President [Outliers] 57:36
How a 91-year-old vibe coded a complex event management system using Claude and Replit | John Blackman
Manage episode 490327836 series 3660816
John Blackman, a 91-year-old retired electrical engineer, shares how he used Claude and Replit to build a complex application for his church’s community service events—with no prior software development experience and for less than $350. His app allows event organizers to create events, recruit volunteers, and manage sign-ups, with a standout feature for organizing free oil changes for participants.
What you’ll learn:
- How John used Claude to create detailed product requirements and user stories
- John’s philosophy on embracing new technology throughout his career
- The exact process for integrating third-party APIs (like VIN lookup for oil changes) with minimal technical knowledge
- How he automated report generation for volunteer management and resource planning
- How the software generates personalized Impact Passports for event participants
- Why letting AI build without preconceived notions of “correct” implementation can lead to faster, more functional results
- How to troubleshoot common development-to-production issues when working with AI coding tools
