Chi sono
Senior Cloud/SRE Engineer with 5+ years designing secure AWS environments. As an AWS Certified Solutions Architect (Professional), I build scalable systems and manage production stability. My real expertise comes from years of firefighting production issues and engineering systems that stay running at scale. I prioritize clean, maintainable infrastructure. Key achievements include leading cloud migrations, executing zero-downtime RDS upgrades, and automating patching via SSM. Notably, I reduced AWS costs by 35% through optimization.
