🛍️ Webstore Codebase Mastery

A 10-week implementation-focused course for becoming productive in a production ecommerce monorepo.

Course Mission

This course is for students who already know TypeScript basics and are ready to work in a real company codebase. Each week targets a practical delivery skill: architecture navigation, API safety, provider abstractions, testing, integration security, performance, and capstone delivery.

Weekly structure: concept lesson, guided pair session, one independent ticket, code review, and checkpoint.
