Extending Claude Code Worktrees for True Database Isolation

Hi, my name is
Damian Galarza
I help builders ship better software with AI.
Currently a Senior Software Engineer at August Health, where I build clinical software that helps senior living operators deliver better resident care. Previously CTO at Buoy Software, where I grew the team from zero to 50+ and shipped FDA-cleared medical device software.
I advise founders and teams on architecture, AI integration, and engineering execution. 15+ years building production systems has taught me that trade-offs matter more than best practices — and I enjoy helping teams navigate those decisions.
If you're building in healthcare, SaaS, or applied AI, I'd love to hear about it.
