Postgres since 2005 ยท Founder of PostgresAI ยท San Diego, CA
Key interests:
- Database health in all its aspects
- Zero-downtime operations, experiments, benchmarks, making DB testing fast and affordable (e.g., zero-downtime Postgres upgrades at GitLab)
- Scaling not only Postgres but also the operations and teams around it
- RCAs
Currently building tools to make Postgres self-driving.
Current open-source projects
- pgque โ Zero-bloat Postgres queue. No extensions. No daemon. One SQL file. A revival of PgQ, ancient art from Skype.
