About
Alejandro Sotillo
SRE · DevOps · Cloud Engineer
I am a Site Reliability Engineer (SRE) and DevOps Engineer with over 9 years of specialized experience in designing, implementing, and operating cloud infrastructure, systems automation, and container orchestration within high-availability environments—backed by more than 17 years in the IT industry.
My focus is on process automation, platform optimization, and service resilience, applying best practices from SRE, DevOps, and Cloud Engineering to maximize operational efficiency and service reliability.
I've helped engineering teams move from manual deployments to fully automated CI/CD pipelines, migrate monoliths to microservices on Kubernetes, and build observability stacks that turn reactive firefighting into proactive operations. I believe infrastructure should be versioned, tested, and reviewed like any other code—and I build systems that reflect that philosophy.
