About

Agentic AI Engineer | Supply Chain Technologist I’m a data-driven project leader passionate about applying AI and emerging technologies to solve complex business challenges. With a foundation in Statistics and Data Science (UCLA) and 5+ years leading digital transformation in manufacturing and supply chain, I bring a unique mix of strategic thinking and technical hands-on experience. Recently, I’ve stepped deeper into AI, where I’ve: • Fine-tuned DeepSeek R1 models using LoRA and Unsloth on remote Linux servers via SSH • Built and deployed Retrieval-Augmented Generation (RAG) systems using Ollama, FAISS, and Gradio • Integrated these solutions into real-world workflows for planning, analytics, and automation I’ve also led full-scale implementations of ERP, MES, and APS systems, driving cost reduction, inventory control, and forecasting improvements. My strength lies in bridging business needs with tech solutions—ensuring AI projects deliver measurable ROI and operational impact. 💡 What I bring to the table: • End-to-end project management (Agile/Waterfall) • AI/ML tools + supply chain intelligence • Strong communication with both technical and business stakeholders 🔧 Tech Stack: Python, Power BI, SQL, VS Code, RPA, FAISS, Ollama, Gradio, ERP (FOSS), APS, MES Let’s connect if you’re working on: ✅ AI/ML deployment in enterprise ✅ LLM projects, fine-tuning, or RAG ✅ Digital transformation in operations/supply chain ✅ Building cross-functional AI teams
