Who is Charlie Tang Hoong?
Charlie Tang Hoong is a forward deployed AI and automation engineer based in Selangor, Malaysia, with 15+ years of production software delivery across AdTech, e-commerce, logistics and enterprise automation. He works on applied AI, workflow automation, solution architecture and enterprise integration for customers in Malaysia, Singapore and the wider APAC region.
What does he actually do?
He takes an ambiguous business problem — usually inside an operation that is already running and cannot stop — works out what the real constraint is, designs the solution, builds the critical parts himself, and carries it into production. Recent work spans hybrid OCR and LLM document processing, AI customer-support systems, RPA across finance and logistics, and backend APIs in Python, Node.js and PHP.
Does he have production AI experience, or only prototypes?
Both, and he distinguishes between them. In production: a hybrid OCR and LLM document-processing pipeline with a human review queue at a global logistics operator, and AI customer-support engineering — knowledge structure, tool integration, session handling, evaluation and safety controls — on a live e-commerce platform. As proofs of concept: LLM evaluation with golden datasets and Ragas checks, agentic LangGraph workflows, and vector-store comparisons.
Is he available in Singapore?
He is based in Selangor, Malaysia, and open to Singapore-based and regional APAC projects as well as client-site work in the Klang Valley, including long-term placement.
What languages does he work in?
English, Mandarin Chinese and Bahasa Malaysia, all at professional working proficiency.
