Anuradhapura Central College
G.C.E. Advanced Level — Physical Science
Where the problem-solving started.Prologue · Malabe, Sri Lanka
I build machine learning models.
A software developer who turns ideas into intelligent, production-ready systems — from trained ML models to the full-stack platforms an entire campus runs on every day.
Chapter 01 — The Spark
Every developer has a Hello, World. Mine compiled in Anuradhapura — somewhere between physics equations and a stubborn need to know how things work. Then curiosity found its syntax. I swapped formulas for functions, theories for test cases, and I've been shipping answers ever since.
