Machine Learning Engineer at IronOne Technologies, fine-tuning local LLMs for document summarization and building retrieval-backed services.
Sri LankaWhat I'm looking for
At IronOne Technologies, I deployed and fine-tuned local LLMs for document summarization, benchmarking quantization and long-context chunking strategies. I also applied SFT/DPO fine-tuning with QLoRA and built backend services using FastAPI, PostgreSQL, and FAISS-based retrieval via LangChain.
For my final year research project, AI-Driven Cyber Threat Intelligence, I developed a pipeline that brings web, Telegram, and PDF sources into a Neo4j knowledge graph. I fine-tuned SecureBERT for entity recognition and built a RAG-based analyst query interface; I’m co-authoring an IEEE conference paper on this work for BuildSEC'26.
