About
My work has always revolved around one mission:
keeping critical systems stable, fast, and resilient.
From performance tuning to large-scale migrations, from high-availability design to automation pipelines, I’ve lived the real-world challenges that DBAs and infrastructure teams face daily — and this blog is where I share what actually works.

Why This Blog Exists
Technology is full of noise. Most documentation assumes perfect environments.
Real life is messier.
This blog focuses on clear explanations, real examples, and solutions tested in production, not on theoretical fluff.
If a script, technique or configuration appears here, it’s because it solved something meaningful for me or for a team I’ve worked with.
Who I Am (Professionally)
- 10+ years as a Database Administrator & Infrastructure Engineer
- Experience in large-scale enterprise environments in Brazil, Ireland and the United States
- Background in high-availability architecture, performance tuning and automation
- Passionate about simplifying complex systems and sharing knowledge
When I’m not tuning queries or breaking and fixing containers, I’m building long-term stability for teams and helping other professionals grow their skills.
