About me
I am a Computer Science and Engineering graduate from the University of Moratuwa, specializing in Cyber Security with strong experience in secure software engineering, cryptographic protocols, cloud security architectures, and AI-driven systems.
With extensive hands-on work in backend systems, distributed platforms, applied cryptography, and agentic AI solutions, I have built a solid foundation in designing resilient, scalable, and secure systems. I am passionate about research in cloud security, privacy-preserving cryptographic mechanisms, secure distributed computation, and trustworthy AI systems.
