Senior AI Engineer at SkureLabs building agentic malware detection systems and production AI applications with multi-agent workflows.

Message

At SkureLabs, I designed and developed an agentic AI malware detection system using LangGraph, with agents that share evidence, assess conclusions, and determine next actions.

I also engineered production SLM classifiers and developed a multi-agent chatbot that retrieves information from SQL databases, documents, and live web search. I deployed it to AWS with Docker and a GitHub Actions CI/CD pipeline.

At Centre for Development of Advanced Computing (C-DAC), I built and deployed an on-premise RAG semantic search system with hybrid search and cross-encoder reranking. I also developed a custom LLM reranker that improved nDCG@10 by 15%.

My work has included fine-tuning language models for named entity recognition, maintaining GPU-based AI services, and improving model robustness through semi-supervised learning. I’m currently researching domain-adapted SLMs for low-compute deployment.
