Kavishka Dinajara
I'm a software engineer based in Colombo, Sri Lanka, with a deep passion for where science meets code. I find the same elegance in a well-structured algorithm that I find in a physical law — both describe the universe with beautiful precision.
Currently at Agrithmics (Pvt) Ltd building the AgriGen ERP platform — a full-scale tea & plantation management system. My final year project explores edge-based Small Language Models for semantic file transformation.
Off the keyboard: rugby pitch, camera in hand, or buried in a mathematics textbook. Every discipline teaches you to think more precisely.
Associate Software Engineer

- Architected a Multi-Pack Invoice Configuration feature using a Bridge Table pattern, enabling backward-compatible schema changes across 7 screens with a unified SQL view and a reusable React MultiPackInput component.
