About

Hello! 👋

I'm Md Shajidur Rahman Almazee. I've spent about five years in DevOps engineering and four years in software engineering helping teams ship reliably, automate confidently, and keep production systems observable and healthy.

On AWS, I work with EC2, RDS, VPC, IAM, Lambda, SNS, SES, and load balancers. I'm at home with containerization and orchestration using Docker, Docker Compose, and Kubernetes, and CI/CD with GitHub Actions and Jenkins. I also bring strong Linux administration and infrastructure fundamentals: networking, DNS, VPN, and load balancing.

Day to day, I work with web servers and backends such as Nginx, Apache, PHP, and Node.js (NestJS, Express, Sails.js), alongside JavaScript and TypeScript. For data, I use MySQL/MariaDB, AWS RDS, and Typesense. I rely on monitoring and observability tooling like Sentry and CloudWatch, and I've built and maintained environments on virtualization and storage platforms including Proxmox and TrueNAS.

I'm also comfortable on the frontend with React and Tailwind CSS when the work calls for it whether that's shipping features, supporting internal tools, or bridging the gap between UI and infrastructure.

Thank you for stopping by. If you'd like to connect, reach out below I'd love to hear from you.
