Fundamentals, a full SaaS build, and the business side — payments, domains, hosting, SEO — are covered in about twelve hours of video instead of the dozens of hours a conventional JavaScript course spends on topics you will never use.
Rather than theory for interviews, you progressively build a real authenticated, paying SaaS, which is the actual deliverable of the course.
Sections on AI-powered coding and design show how to use AI to explain code, fix bugs and generate parts of your app, framed as leverage on top of fundamentals.
The syllabus includes the non-coding skills that decide whether an app makes money: copywriting essentials, payments with Stripe and LemonSqueezy, domain and DNS setup, hosting and SEO.
Agentic skills intelligence for hiring, developing, and planning talent
Technical, business, agentic, behavioral, and diagnostic evaluations built around real job tasks.
Structured conversational interviews that give teams clear skills evidence early in the funnel.
A shared workspace where candidates solve real problems while interviewers observe how they work.
See where your workforce is strong, spot gaps early, and plan hiring, mobility, and redeployment.
