I've built and shipped production full-stack web applications, backend APIs, and AI-powered features at Saks Global, Neiman Marcus Group, and Cox Automotive.

At Saks Global, I developed React, Next.js, TypeScript, Node.js, and Python applications; designed SQL schemas and persistence layers; and integrated external APIs and AI/LLM services for intelligent product features and workflow automation. I work across UI development, backend architecture, authentication, validation, database design, debugging, and cloud deployment.

Previously, I delivered secure, data-driven applications with REST APIs, role-based access, PostgreSQL, MySQL, and third-party integrations. I also built TurboLog, a vehicle maintenance tracking application with authentication, vehicle management, maintenance logging, and community features.
