• Cloud Computing Fundamentals & Architecture: Expertise in core cloud concepts, including the three main Service Models (IaaS, PaaS, SaaS) and diverse Deployment Models (Public, Private, Hybrid, Multi-cloud).
• Modern Application Deployment Strategies (GCP Focus): Instruction on the GCP Application Hosting Spectrum, covering Virtual Machines, Containers (Kubernetes and Cloud Run), Platform as a Service (App Engine), and Serverless Computing (Functions as a Service - FaaS).
• Data Management & Big Data Analytics: Comprehensive coverage of Cloud Storage options (Object, Block, File) and Database solutions, including Relational (Cloud SQL), NoSQL (Firestore, BigTable, Memorystore), and serverless enterprise data warehousing (BigQuery).
• DevOps and Infrastructure Automation: Skills in DevOps principles, including Continuous Integration (CI), Continuous Delivery (CD), Infrastructure as Code (IaC) using tools like Terraform, and implementing effective Monitoring and Logging for system observability.
• Emerging Technologies & Responsible Cloud Use: Focus on crucial topics like Cloud and IoT Security, Identity and Access Management (IAM), data privacy, and the ethical considerations of cloud and massive data collection.

Cloud Infrastructure & Governance

• Foundation: Built a modular GCP foundation using Terraform, ensuring strict separation between Dev and Prod environments.
• Networking: Designed a secure Hub-and-Spoke topology with Shared VPCs, Private DNS, NAT Gateways, and Next-Gen Firewalls for strong isolation.
• Hybrid Cloud: Connected on-premise infrastructure to GCP via secure, high-availability Cloud VPN tunnels.

Kubernetes & DevSecOps Platform

• Platform Engineering: Built a private, production-grade GKE cluster with a secure Software Supply Chain.
• Tooling Suite: Integrated ArgoCD (GitOps), Keycloak (IAM), Falco, Kyverno, Trivy, and SonarQube for continuous security, quality, and compliance scanning.
• Automation: Used GitHub Actions to automate platform setup and deployments, enabling developer self-service and faster velocity.

Data Strategy & Resilience

• Databases: Deployed highly available PostgreSQL clusters on GKE using the CloudNativePG operator.
• Disaster Recovery: Automated backups to Google Cloud Storage and performed regular restore validations to ensure business continuity.

Security & Identity Management

• Workspace Admin: Managed the full Google Workspace setup, aligning configurations with security policies.
• IAM Framework: Structured IAM with Organizational Units (OUs), enforced 2-Step Verification, and configured DLP rules and Google Vault for compliance.
