What I'm looking for

I'm looking for opportunities to contribute to practical AI products, learn from experienced professionals, collaborate on challenging problems, and grow into a well-rounded engineer.

I've built Slashus, a Sinhala AI tutor that delivers citation-grounded textbook answers, personalized quizzes, and automated assessment. I engineered its memory-augmented ReAct agent, achieved 92%+ Recall@10 with BGE-M3 and Qdrant hybrid retrieval, and delivered containerized FastAPI, Go, gRPC, PostgreSQL, and Redis services.

Across RAG, computer vision, and machine learning projects, I've built an automotive chatbot with 97.12% intent-classification accuracy, a fruit classifier reaching 92.94% test accuracy, and a YOLOv11m pill detector with 0.995 mAP@50. I'm looking to contribute, learn from experienced professionals, and grow into a well-rounded engineer.
