# About

I'm Dineth, an AI/ML engineer focused on shipping production-ready systems: RAG pipelines, ML infrastructure, and developer-facing AI tools that work beyond the demo stage.

Currently building AI for education at [BrainUs LK](https://brainus.lk) while finishing my CS degree at the University of Plymouth. My work spans retrieval architecture, backend APIs, and ML workflows.

Open to AI/ML engineering and applied AI roles where the goal is systems that are reliable, explainable, and actually used.
