ABOUT ME

I am an engineering undergraduate at the Department of Computer Science & Engineering, University of Moratuwa, passionate about building reliable software that spans from resilient backend microservices to autonomous agentic AI architectures.

My engineering philosophy revolves around high-leverage systems: designing scalable REST & WebSocket APIs with FastAPI and Node.js, engineering multi-agent LLM boards using LangGraph and ChromaDB RAG, and crafting performant mobile experiences with React Native (Expo) and Kotlin Jetpack Compose.

Beyond coding, I actively contribute to engineering communities as an Event Compere and Organizing Committee lead for events like SLT Robogames, SLIOT, and Octwave 2.0.

RESEARCH & BUILDS

Multi-Agent AI 2026

Multi-Agent AI Treatment Reviewer

Architected an autonomous multi-agent AI medical board utilizing LangGraph comprising three specialized agents (Clinical Pharmacist, Medical Compliance Officer, and Supervisor) that collaboratively critique and validate patient treatment plans.

  • Integrated RAG pipeline with LangChain, ChromaDB, and Google Gemini Embeddings to query authoritative WHO guidelines.
  • Engineered autonomous tool-calling agents for real-time drug-drug interaction detection.
  • Deployed as a Gradio web application on Hugging Face Spaces with automated GitHub Actions CI/CD.
