Betzalel Moskowitz
Senior GenAI Engineer
I design and deploy production-grade AI systems — from LLM agents and RAG pipelines to data engineering and ML research. Based in New York.
What I Offer
Services
Production-grade AI engineering and strategic consulting — whether you need a standalone system built or guidance on where to start.
LLM & Agentic AI Development
End-to-end development of tool-using, multi-step LLM agents. From prompt engineering and chain design to LangChain/LangGraph orchestration and production deployment.
RAG & Knowledge Graph Systems
Architecture and implementation of retrieval-augmented generation pipelines, vector databases, semantic search layers, and knowledge graph integration for grounded AI outputs.
Data Engineering & ETL Pipelines
Design and build robust data pipelines, ingestion workflows, and transformation layers. Expertise in SQL, Postgres, orchestration, and production-grade ETL systems.
ML Model Development & Evaluation
Supervised and unsupervised model development, deep learning training (PyTorch/TensorFlow), experiment design, evaluation frameworks, and responsible AI practices.
AI Strategy & Advisory
Strategic guidance on AI adoption, architecture decisions, and roadmap planning. Helping organizations identify high-impact use cases and build AI-native workflows.
Web Development
Building modern, performant web applications and APIs. From full-stack development to SEO optimization and cloud deployment — clean code with a focus on user experience.
Data Science Tutoring
One-on-one and small-group tutoring for students and professionals looking to build or sharpen data science skills. Covers Python, SQL, machine learning concepts, and hands-on project work.
Data Analytics
Turning raw data into clear, actionable insights. Exploratory analysis, dashboards, KPI frameworks, and reporting pipelines — helping teams understand what their data is actually telling them.
Background
About Me
I'm a Senior GenAI Engineer at TRACTIAN, where I build production AI systems for industrial maintenance — including a LangGraph agent that generates full customer assessments autonomously in under a minute, a custom MCP server exposing 20+ enterprise tools to LLM agents, and fine-tuned LLMs trained on 1,000+ proprietary documents using LoRA.
Before that, I spent four years at The MITRE Corporation — rising from ML intern to Senior AI Engineer — working on national-security and public-good programs. There I architected agentic chatbots backed by PostgreSQL and Neo4j knowledge graphs, led LLM infrastructure strategy, and developed a computer vision model for drone imagery that is currently under patent application.
I hold a 4.0 GPA M.S. in Data Science from Northwestern University and a 3.96 GPA B.S. in Information Science (Magna Cum Laude) from the University of Maryland. Outside of my full-time role I take on freelance engagements — from greenfield AI builds to architecture reviews and strategic roadmaps.
