Senior AI + Full Stack Engineer with over 10 years of commercial experience building scalable, production-grade web applications using Ruby on Rails, AWS, and modern JavaScript stacks. I’ve led engineering across SaaS platforms processing 150,000+ daily requests, optimized performance at scale, and built full pipelines from integrations to customer experience.

Recently integrated AI into enterprise-grade products — building GPT-4 powered chat workflows, auto-reply systems, and internal tooling using LangChain, OpenAI APIs, and Python. I’m highly experienced in RESTful API design, external platform integrations (Yardi, RentCafe, Entrata, Resman, WelcomeHome), and building internal tools for marketing automation, analytics, and guided user journeys.
