Software Engineer → Cybersecurity
IT undergraduate building REST APIs, full-stack apps, and CI/CD pipelines. Steadily moving toward application security, cloud security, and DevSecOps.
Galle, Sri Lanka
I'm Shums Marickar Fawzul Shayila — a 4th-year IT undergraduate with a hands-on focus on backend development, DevOps automation, and cloud-aware system design.
My path started with Python and machine learning, grew into building Java full-stack systems with Spring Boot and React, and is now pointing firmly toward application security and cloud security. I automate what I can — CI/CD pipelines, containerised deployments, and repeatable infrastructure.
I build things that are functional, secure by default, and clean to maintain. Ethical note: I only test systems I own or have explicit permission to test.
