πŸ‘©πŸ½β€πŸ’» About Me

Versatile and impact-driven Data Engineer, with solid experience as a DevOps and MLOps Engineer. I design, build, and optimize data infrastructure and pipelines that power analytics, applications, and AI systems in production. With 5+ years of hands-on experience, I specialize in delivering reliable, secure, and automated data and deployment workflows across AWS, Azure, and hybrid environments.

My work lies at the intersection of data infrastructure, pipeline automation, and cloud-native engineering, ensuring that data is accessible, trustworthy, and actionableβ€”at scale.
