Overview
AI/ML Engineer and CTO with 20+ years shipping production software and, over the past decade, large-scale machine learning and LLM systems. I design and deliver end-to-end AI products: LLM-powered agents, retrieval-augmented generation (RAG) pipelines, fine-tuned open-weight models (Llama, Mistral), and the MLOps infrastructure to serve them reliably at scale. Hands-on with PyTorch, TensorFlow and Hugging Face Transformers, modern LLM tooling (LangChain, LlamaIndex, vLLM) and vector search (FAISS, Pinecone, Qdrant). I own the full lifecycle - from data pipelines and model training to low-latency, cost-efficient inference in production - while leading engineering teams and turning research into dependable, revenue-driving products.

Alion is an AI talent discovery platform for developers and hiring teams. It builds rich profiles from public GitHub, papers, and projects and surfaces explainable matches across AI, backend, robotics, security, and more. Companies search by up to 127 public signals and send opt-in outreach, while developers keep full control of visibility, salary expectations, and data. An AI screening feature verifies skills and flags against real code and resumes, helping teams qualify candidates before interviews and improving reply rates with transparent, developer-first workflows.
