À propos

Introduction

AI/ML Engineer with 3+ years of experience designing and deploying ML and LLM systems end-to-end, from data pipelines to production serving. Core expertise in NLP, classification on imbalanced datasets (XGBoost), retrieval systems (RAG, hybrid search), and agentic LLM architectures (LangGraph, MCP). Most recently Lead AI Engineer at MyUnisoft, where I built a multi-class transaction classifier reducing manual categorization by 70%, led AI governance, and ran cross-functional workshops.
