- Managed and secured hybrid AWS and Azure infrastructure, leveraging advanced IAM, RBAC, and Azure Entra ID (formerly Azure AD) to centralize and automate identity and access management, including integration with on-premises AD and external SaaS vendors for seamless SSO and governance. Led the creation and enforcement of granular IAM policies and custom RBAC roles across cloud environments, supporting compliance and least-privilege principles for critical services like EC2, S3, RDS, Lambda, Glue, and bespoke business use cases.
- Designed cloud networking with robust VPCs, subnets, security groups, and VPN configurations, ensuring secure, scalable interconnectivity between platforms. Implemented and maintained reliable ETL pipelines using AWS Glue for automated data transformation from S3 to RDS, optimizing business data workflows. Established cross-account IAM roles to share resources between isolated AWS environments, and architected secure app authentication via Azure application registrations, service principals, and managed identities.
- Drove business process automation by deploying Azure Logic and Function Apps, and improved reliability and scalability of third-party integrations by efficiently troubleshooting and collaborating with key vendors. Ensured high application uptime and compliance by configuring T-Mobile Kubernetes Engine (TKE) clusters—with autoscaling, rolling updates, and robust CI/CD pipelines—deploying to dev, staging, and production, and enforcing zero-downtime releases through infrastructure as code and dynamic GitLab and Jenkins workflows.
- Reduced system outages by quickly diagnosing and resolving REST API and IIS server issues, leveraging in-depth log analysis, Event Viewer, and real-time monitoring. Automated operational tasks across Linux and Windows using custom shell/PowerShell scripts for patching, installations, and service restarts. Architected end-to-end monitoring and incident response with Splunk and Datadog, integrating tailored alerts directly into Teams, PagerDuty, or email for maximum incident visibility. Troubleshot system-level issues across Linux and network stack components (CPU, memory, disk, NFS, DNS, TCP/IP, SSH).
