About Me

Vidun Jayakody

Hey 👋🏽, thanks for stopping by! I'm a recent Computer Science graduate currently working at Cisco as a Site Reliability Engineer on the Cisco XDR team — Cisco's threat detection and response platform.

I enjoy diving into the operational side of engineering, where performance, reliability, and security all intersect. Outside of infrastructure, I stay curious about cloud architecture, observability, and the evolving threat landscape in cybersecurity.

My current tech stack includes AWS, Terraform, Kubernetes, Python, Bash, Datadog, and Splunk, and I'm always learning more. Keep scrolling to see what I've built, where I've worked, and what I can bring to your team.
