// Experience

AI / ML Engineer Intern

MintHRM — Colombo, Sri Lanka

Sep 2025 – Present
  • Designed and implemented a RAG-based HR chatbot pipeline, integrating document ingestion (Docling), advanced chunking, embedding generation, vector database, and hybrid retrieval strategies.
  • Researched, architected, and developed a LangGraph-based multi-agent system (POC) featuring supervisor-agent orchestration, specialized sub-agents, structured graph workflows (nodes/edges), tool routing, session-based memory, and human-in-the-loop interaction checkpoints.
  • Engineered tool-calling and function-calling pipelines, enabling controlled LLM task delegation, external API integrations, and deterministic workflow execution.
  • Integrated and evaluated open-source LLMs (LLaMA 3, Qwen via Ollama), applying prompt engineering and tool-selection refinement for improved reliability.
  • Built and exposed backend services using APIs, containerized components with Docker, and extended workflows with multimodal capabilities (OCR, Speech-to-Text, Text-to-Speech).
  • Produced technical documentation and presented the multi-agent architecture POC to internal stakeholders.
