sadev@sys:~$whoami

I'm a BICT (Hons) undergraduate at the University of Kelaniya, specializing in Computer Networks and building toward a career in Cloud & DevOps engineering. My focus is designing cost-efficient, serverless-first architectures on Microsoft Azure that scale to zero when idle and hold up under real production load.

I enjoy the space where infrastructure, security, and code meet — wiring CI/CD pipelines through GitHub Actions, containerizing services with Docker, and instrumenting systems with Grafana and Prometheus. On the backend I lean on Python, Django, and both SQL and NoSQL data stores.

Currently deepening my Azure expertise (AZ-900 in progress), collecting Microsoft Learn badges, and open to internship opportunities where I can ship real infrastructure alongside a strong engineering team.
