About Scott Koskoski

I build machine learning systems that run in production — not just notebooks. Over 6+ years across logistics, retail, and fintech, I\'ve taken models from research to deployment: GPU-accelerated freight optimization on 1M+ shipments, a real-time fraud detection platform processing 21K+ TPS through Kafka with XGBoost scoring at sub-10ms latency, and an internal RAG chatbot grounding a 120B-parameter LLM in company knowledge via TF-IDF retrieval.Currently a Senior Analytics Engineer at Green Mountain Technology, I work daily in Python, SQL, and cloud infrastructure to ship end-to-end ML products. My sweet spot is the full pipeline — data engineering, model training (PyTorch, XGBoost, scikit-learn), MLOps (drift detection, automated retraining, model versioning), and serving via FastAPI or streaming architectures. I write the React/TypeScript frontend when the project needs one, but my focus is on the ML systems underneath.What sets me apart: I pair deep ML engineering with an economics background (M.A, University of Memphis) that keeps me anchored to business impact. Every system I build ties back to a measurable outcome — dollars saved, hours eliminated, decisions accelerated.Currently finishing my M.S. in Computer Science at UT Knoxville (Data Mining & Intelligent Systems, 2026). Always interested in connecting with teams building production AI/ML infrastructure.Explore my code & projects: https://github.com/scottkoskoski

Experience

1. Senior Analytics Engineer

   Green Mountain

   Nov 2025 — Present · Memphis, TN, US

   Scaled a SQL-based pricing analytics platform by designing data transformations, building rate table pipelines, and extending calculation logic to support new business entities and vendor integrations- Built an internal RAG chatbot grounding a self-hosted 120B-parameter LLM (Ollama) in a 65-page Confluence knowledge base using TF-IDF section-level retrieval with conversation-aware context boosting – zero per-query API calls, deployed via Docker Compose and Open WebUI.
