Cesar Castillo

WHO I AM

I design and build AI-powered lifecycle marketing platforms, MarTech systems, and multi-ESP architectures that help organizations scale customer engagement. My work spans lifecycle strategy, marketing technology, reusable systems, customer journey orchestration, personalization, and cross-functional implementation across marketing, engineering, product, and data teams. Using AI, structured prompting, rule-based validation, and ESP technologies, I build internal tools and scalable workflows that improve operational efficiency, automate production, and deliver reliable customer communications at scale.
