Hi, I'm Yong 👋

Cloud & DevOps Instructor · Builder · AWS Certified DevOps Engineer – Professional

I teach cloud computing and emerging infrastructure technologies, while building practical cloud-native applications and hands-on labs.

My current interests are AWS, DevOps, cloud architecture, AI infrastructure, serverless systems, and developer-focused products. I also hold an M.Sc. in Computer Science from the University of Saskatchewan, where my research focused on blockchain-based access and usage control for cloud-based Digital Twins.

Currently

  • ☁️ Teaching cloud computing, DevOps, and infrastructure technologies
  • 🚀 Building OfferWorth — a Canadian job-offer and after-tax salary comparison tool
  • 🤖 Exploring practical AI infrastructure and cloud-native AI applications
  • 🧪 Designing hands-on AWS labs around CI/CD, containers, serverless, networking, and cloud security
