I'm Dan Wang, a Senior Cloud Engineer with 5+ years of hands-on Google Cloud experience. I hold active Google Cloud certifications across the architect, developer, networking, and machine-learning tracks — Professional Cloud Architect, Professional Cloud Developer, Professional Cloud Network Engineer, and Professional Machine Learning Engineer — plus AWS Solutions Architect Associate.

Day-to-day, I design and build production cloud platforms for enterprises across financial services, retail, logistics, and healthcare.

I teach because I've spent enough time in real design reviews to know the gap between passing the exam and making the right call under pressure — and I think practice material should close that gap, not widen it. My courses focus on realistic scenarios, the trade-offs that actually matter in production, and the why behind every answer, with citations to official documentation so you can verify and go deeper.

If you're studying for a Google Cloud certification or levelling up your cloud architecture skills, I hope my courses help you get there faster.
