Iterating the plan and coding patterns

Joe McCormick is a principal software engineer at Babylist who lost most of his central vision due to a rare genetic disorder right before starting college. He pivoted from mechanical engineering to computer science and now leads AI enablement at Babylist. Joe demonstrates how he uses AI to build micro Chrome extensions that make his everyday work and life more accessible, showing how personal software can address accessibility needs that mainstream products often overlook.

What you’ll learn:

1. How to build custom Chrome extensions in under 25 minutes using Claude Code
2. A practical workflow for creating AI-powered accessibility tools
3. How to use Claude Skills to accelerate repetitive development tasks
4. Techniques for making Claude Code more screen reader accessible
5. Why personal software is becoming increasingly viable with AI assistance
