About

Hey ๐Ÿ‘‹๐Ÿฝ, 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 โ€” Ciscoโ€™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, and Datadog โ€” and Iโ€™m always learning more. Keep scrolling to see what Iโ€™ve built, where Iโ€™ve worked, and what I can bring to your team.
