Cloud Migration and Automation

I worked on cloud migration of SCADA systems in the electricity production industry. As an Azure architect, I provided guidance for cloud governance, migration processes, development/testing and production environment definition, infrastructure as code and provisioning, CI/CD processes, and pipelines setup for microservices' deployment automation.

Cloud Governance and Self-serving Initiative

I worked in an enterprise-grade multi-environment in the mature stages of cloud adoption with Azure. The product development was under agile methodologies, and it was cloud native in essence. Multiple vendors and their own teams from the client were working on product and feature development for big data, analytics, IoT, and ML in the road for AI implementation for customers and end users.

I was part of a solution and enterprise architecture board in charge of designing a new governance model to enable several key teams to reach the goal of having entire autonomous product development teams: self-serving their infrastructure, aligning their technical skills and working toward the best practice framework, complying with cloud architecture, building a zero trust security model, and fully automating processes.

Data Center Migration to Azure Cloud

I worked on a long-term project to assess, plan, and execute a migration of over 1,500 servers from an on-prem data center to Azure with different transformations directly to VMs, app service web apps, functions, containers, and microservices.

All cloud resources were treated as IaC using Terraform and Azure DevOps. All the applications that could be modernized with the least effort (mostly those written in C# and Python) were converted to cloud-ready and some to cloud-native services and were deployed and maintained using ADO CI/CD pipelines.
