ABOUT DENNIS CHENG
Applied AI & Automation System Engineer with a background as a System Analyst and iOS developer, with over 13 years of experience building and scaling digital products.I specialise in designing end-to-end AI-powered automation and orchestration systems that turn unstructured inputs (text, images, files, and user requests) into structured decisions and automated actions. My work focuses on applying LLMs and automation tools such as n8n to real operational workflows, including content moderation, decision routing, internal knowledge systems, data reporting, and system operations.Previously, I led and contributed to mobile app development (iOS, Swift, SwiftUI, Objective-C), system analysis, and CI/CD automation across frontend, backend, and infrastructure. This hybrid background allows me to bridge product, engineering, and operations, and to design systems that are both technically robust and practical for real-world use.
