Certifications & Credentials
Projects I Have Built
Here are some of the infrastructure and platform projects I have worked on. Each one taught me something new about building reliable systems at scale.
Terraform Academy Platform
A learning platform I built for teaching Infrastructure as Code. It has interactive labs, progress tracking, and supports multiple organizations with SSO.
Key Features
- Interactive IaC coding labs
- Progress tracking and certifications
- Multi-tenant organizations with SSO
- Subscription management
AWS DR Automation
Cross-region disaster recovery that fails over in under 15 minutes. I built this using Route53, RDS replication, and Step Functions to automate the entire process.
Key Features
- RTO under 15 min, RPO under 5 min
- Health-based DNS failover
- Cross-region RDS replication
- Automated runbook execution
AWS EKS Observability
A complete observability stack for Kubernetes. Prometheus for metrics, Loki for logs, Tempo for traces, all tied together with Grafana dashboards.
Key Features
- Unified metrics, logs, traces
- IRSA for secure AWS access
- Long-term S3 storage
- Pre-built dashboards
AWS Security Compliance
Security scanning and auto-remediation built on Security Hub, GuardDuty, and Config. When something drifts out of compliance, Lambda functions fix it automatically.
Key Features
- CIS/PCI-DSS/SOC2/HIPAA compliance
- Auto-remediation workflows
- Real-time security alerts
- Compliance dashboards
AWS Landing Zone
Multi-account setup using AWS Organizations and Control Tower. I automated account provisioning and set up SCPs to keep everything secure by default.
Key Features
- OU hierarchy management
- Preventive SCPs
- Account factory automation
- Centralized logging
AWS CI/CD Pipeline
Production deployment pipeline using CodePipeline and CodeBuild. Supports blue-green and canary deployments with automatic rollback if something goes wrong.
Key Features
- Blue-green deployments
- Cross-account promotion
- Container scanning
- Automated rollback
Plus 4 more projects including AWS Cost Optimizer, Instance Scheduler, Server Tagging Module, and Homeschool Planner PWA.

I have spent over a decade building and running infrastructure for enterprise organizations. Here is a bit about my journey and what drives me.
Enterprise Cloud Infrastructure
I have spent over a decade building and running cloud systems for large organizations. My focus has always been on creating infrastructure that stays up when it matters most.
Identity and Access Management
I administer Active Directory, Azure AD, and Entra ID across multiple domains. I manage user identities, roles, service accounts, and access privileges while ensuring seamless integration with on-premises AD.
Security and Compliance
I run Security Attack Surface Analyzer on new implementations, audit AD Security Groups for compliance, and work with security teams on firewall patches and policy enforcement.
Platform Leadership
I lead platform work across both on-premises and cloud environments. I work closely with security, compliance, virtualization, and networking teams.
Career Timeline
Site Reliability and Platform Engineer
I design and operate cloud infrastructure across AWS, Azure, and hybrid environments. I lead our identity management, observability, and compliance automation efforts.
- Multi-cloud infrastructure (AWS, Azure, GCP)
- Identity governance with Entra ID
