About
Building secure systems and writing what I learn
I am Ashen Dulsanka, a cybersecurity enthusiast and builder focused on secure application design, cloud-native workflows, and hands-on offensive security labs.
Cybersecurity
Practical vulnerability research, penetration testing habits, and secure architecture thinking.
Engineering
TypeScript-first systems, SvelteKit products, and maintainable front-end architecture.
Labs and CTF
Challenge walkthroughs, threat simulation notes, and operational security techniques.
Learning Path
Continuous certifications and open documentation of what works in real projects.
Why this blog exists
This space is my running notebook: practical notes from security labs, software engineering implementation details, and the career lessons that bridge both.
Current mission
Design practical security tools and make learning paths easier for the next engineer.
