Instructor

Hi, I'm Morld's founder — a full-time engineer and amateur fitness enthusiast. I've been writing code for 10+ years; my primary stack is JavaScript / TypeScript / React + Cloud Run / GCP deployments, with C# / .NET, Docker, and DevOps as secondary specialties. My 1-on-1 teaching style is: first understand the outcome you want, then design the chapter order and pace to reach it. Each lesson ends with homework; the next starts with a 5-minute review.
