Full-Stack • IoT • Systems
Hi, I'm Janith.
Building reliable full-stack & IoT systems that actually last
WHO AM I?
B.Sc. Physics & Electronics (UoK) Graduate turned Full-Stack Software Engineer. Currently building responsive frontends, scalable backends, and intelligent IoT systems at Sistena.
I thrive close to the metal - writing clean, testable code and obsessing over failure modes before they become incidents.
Security, performance, and maintainability aren't checkboxes. They're the foundation of software that survives real-world chaos.
