databricks

I design and implement secure, production-grade Data and AI platforms across Azure, AWS, and GCP. Specializing in Databricks architecture, zero-trust security, and infrastructure automation.

🎯 What I Do

🏗️ Build secure data lakehouses with Private Link, Unity Catalog, and data exfiltration protection
☁️ Multi-cloud Databricks architecture for regulated industries (finance, healthcare, government)
⚙️ Infrastructure as Code with modular Terraform templates and automation frameworks
📝 Share knowledge through technical articles and open source contributions
