About me
Welcome to My Homelab Projects
Hi, I’m Sanju Mathew, a DevOps and cloud enthusiast with a solid foundation in Linux system administration and a deep passion for building secure, self-hosted infrastructure. I hold multiple AWS certifications and have over two years of hands-on experience architecting automated, scalable, and production-ready solutions.
From designing CI/CD pipelines and deploying Kubernetes clusters to building observability stacks and enforcing security, I focus on getting things right through careful planning, community-driven learning, and continuous iteration.
Core Skills & Highlights
- Cloud & Infrastructure: AWS (EC2, Lambda, RDS, VPC, IAM, S3), CloudFormation, Terraform
- DevOps & Automation: CI/CD (GitHub Actions, CodePipeline), Ansible, serverless apps
- Containers & Orchestration: Docker, Docker Compose, ECS, Kubernetes (K8S)
- Linux & Networking: Bash scripting, hardening, DNS, NAT, reverse proxies
- Observability: Prometheus, Grafana, Alertmanager, Loki
- Security & Access: Traefik, cert-manager, Tailscale, WireGuard, Let’s Encrypt
I enjoy diving deep into open-source technologies, solving real-world challenges, and sharing practical knowledge.
