Questions, answered
What exactly do I get?
Each course is 9 animated, whiteboard-style video modules (Module 1 is free to watch), with lifetime access and every future update to that course. All-Access Lifetime gives you System Design and AI Engineering today plus all 7 upcoming courses as they launch, for one payment. Watch in any modern browser on your laptop, tablet or phone.
Who is this for?
Anyone who wants to understand how real systems work and level up: from your first job to senior and staff, career switchers and self-taught developers, and anyone preparing for a system design interview. Everything is built up visually, step by step, and interview prep is built in.
How is this different from your free YouTube videos?
The YouTube videos are standalone explainers on one topic each. The courses are a structured path: Module 1 gives you a framework and every later module plugs into it, each topic goes deeper than a short video can, and each course ends with worked case studies, designed end to end. You get an ordered curriculum instead of a recommendation feed, and your progress is saved across devices.
How long does it take?
System Design is 9 modules, about 3 hours of video; AI Engineering is 9 modules, about 2.5 hours of video. Go at your own pace: there are no deadlines, and single courses and All-Access Lifetime never expire.
Will it help with interviews?
It's built around interview frameworks: Module 1 of each course is a repeatable approach for the design round, later modules cover the trade-offs interviewers probe, and each course finishes with full case studies. We can't promise an outcome. You still need to practise out loud, and the courses show you what to practise.
