# Stephen Blatt > Staff Software Engineer | Applied AI & LLM Systems | Developer Tooling & High-Scale Frontend Architecture Location: Culver City, California, United States Profile: https://flows.cv/stephenblatt I’m a Staff Software Engineer specializing in applied AI, large-scale front-end architecture, and developer tooling. My recent work focuses on building reliable AI workflows—LLM function-calling layers, schema-validated pipelines, retrieval systems with embeddings, and AI assistants that turn complex multi-step operations into simple natural-language commands. I’ve designed internal AI agents that safely automate PLM workflows, built an AI PR reviewer using diff analysis + vector retrieval, and created deterministic execution paths around nondeterministic GenAI behavior. My strength is blending systems architecture with practical AI engineering to deliver tools that boost developer velocity and reduce cognitive load. Outside of AI, I’m experienced in modernizing legacy systems with microfrontends, SSR, module federation, and high-performance UI architecture. I work heavily with Webpack, Vite, React, TypeScript, Node.js, and cloud platforms (AWS/Azure), and I’ve led major initiatives involving build-system overhauls, design systems, and microservices. I’m looking for roles focused on applied AI engineering, AI developer tools, LLM-driven workflows, platform engineering, and system-level architecture. ## Work Experience ### Staff Software Engineer @
