Technical depth.
Human clarity.
I am Rasith Senanayake, a cybersecurity-focused developer from Sri Lanka. My work sits between security research, engineering, and communication: finding weak points, building reliable systems, and explaining the fix clearly.
I enjoy hands-on projects where the result has to work in the real world. That includes portfolio sites, admin dashboards, automation tools, API integrations, security labs, and reports that turn technical details into something useful.
This site is a living portfolio for my work, experiments, and contact details. The goal is simple: make it easy to understand what I do and start a practical conversation.
