💡 Science-Backed. Cloud-Packed. Story-Driven. Welcome to Betty@cloud — where DevOps meets curiosity and clean deployments. 🐳

🎓 Certified: 👋 Hi, I’m Betty Musari — a former food scientist now diving deep into the world of DevOps and cloud engineering. I write about my hands-on journey with AWS, Docker, and CI/CD, translating complex concepts into clear, beginner-friendly stories. With a scientific mindset and a passion for continuous learning, I'm on a mission to demystify the cloud — one container at a time. ✨As a Food Technologist & Sales Strategist turned DevOps Explorer, I leverage problem-solving and client-centric skills to build resilient cloud systems. Currently mastering CI/CD pipelines, Azure, and Infrastructure as Code (Terraform) to automate deployments like a well-oiled production line. Passionate about merging operational efficiency with technical innovation—because great systems, like great recipes, require precision and scalability.
