Hi, I'm Ameerul Mujahidin (Ameer Techy).
I am an IT Infrastructure Engineer with 7.5+ years of hands-on experience managing enterprise infrastructure environments including Linux servers, Windows Server, virtualization, networking, backup systems, security platforms, and university-scale IT operations.
This repository documents my complete transition journey into DevOps, Cloud Engineering, and Site Reliability Engineering (SRE) through consistent daily learning, hands-on labs, automation projects, and real-world implementation.
Unlike tutorial-only learning, this journey focuses on:
- Building production-ready skills
- Understanding infrastructure deeply
- Learning by doing
- Documenting everything publicly
- Becoming job-ready through consistency
- Master Linux, Git, Docker, Kubernetes, CI/CD, Terraform, Ansible, and Cloud Technologies
- Build real-world DevOps projects
- Strengthen automation and infrastructure engineering skills
- Transition into a professional DevOps / SRE role
- Share knowledge and progress publicly through GitHub
- Linux & Windows Server Administration
- Virtualization & VM Management
- Enterprise Networking & Wi-Fi Infrastructure
- Backup & Disaster Recovery
- IIS, Apache, Nginx Hosting
- Docker Deployments
- Moodle & OpenProject Infrastructure
- Storage & Endpoint Security Management
- Infrastructure Troubleshooting & Optimization
- Docker & Kubernetes
- CI/CD Pipelines
- GitHub Actions & Jenkins
- Terraform & Ansible
- AWS & Cloud Infrastructure
- Monitoring & Observability
- GitOps & DevSecOps
This repository is organized into daily learning and implementation tasks from Day 1 to Day 90.
