 * Legacy Application Migration: Transition applications running on WebLogic, GlassFish, WebSphere, JBoss EAP, and Tomcat to modern cloud environments.
 * Cloud Architecture: Design scalable microservices, Domain-Driven Design (DDD) patterns, and integration architectures tailored for Azure App Service, Azure Kubernetes Service (AKS), Azure Container Apps (ACA), and Azure Red Hat OpenShift (ARO).
 * Java Modernization: Oversee application upgrades from legacy Java versions (Java 6/8) to modern LTS releases (Java 11/17) and manage Java EE to Jakarta EE migrations.
 * Containerization & CI/CD: Establish robust container strategies (Docker, Kubernetes) and build automated CI/CD pipelines using Azure DevOps and GitHub Actions.
 * Landing Zone & Cloud Integration: Architect integrations with Azure Landing Zones, Azure Storage, Azure SQL, and Azure Key Vault while ensuring strict security hardening, performance optimization, and observability.
