I was born to sail. The sea teaches lessons that reach far beyond the horizon: respect the sea, trust your crew, adapt to changing conditions, and always keep your course, even when the winds shift.
Today, I’m excited to begin a new voyage as Chief Strategy Officer at @proxysql . Every journey begins with a change of course. Sometimes it means discovering new waters. Sometimes it means sailing familiar seas with a new crew. This is one of those voyages.
I’ve spent more than three decades navigating the world of open source databases, infrastructure, high availability, and the incredible communities that have shaped our industry. The waters are familiar, but the opportunities ahead are anything but.
I’m looking forward to helping chart the next course for ProxySQL, working alongside an exceptional team, and continuing to contribute to the open source ecosystem that has given me so much throughout my career.
Fair winds to my new crew, @rene_cannao and @JesmarCannao
Let’s sail ⛵ ⚓ 🔱

Percona Live 2026 showed how broad the open source database ecosystem has become.
MySQL remains strong.
PostgreSQL momentum is impossible to ignore.
Operational challenges are increasingly shared across both.
