📄️ Frontend Engineering as a System
Most engineers misunderstand frontend engineering.
📄️ State Management, Data Fetching & Caching
SECTION 1 — THE REAL PROBLEM: TOO MUCH STATE
📄️ Performance Engineering & Rendering
SECTION 1 — FRONTEND PERFORMANCE IS SYSTEMIC
📄️ Testing, Reliability & Backend Collaboration
SECTION 1 — FRONTEND RELIABILITY IS USER TRUST
📄️ Fullstack System Design
Senior fullstack engineers don’t just “build screens” or “ship endpoints.”
📄️ Frontend-Backend Contracts
The fastest teams are not the ones with the best framework.
📄️ End-to-End Performance Budgets
Users experience performance as one thing.
📄️ Reliability Patterns Seniors Ship
Production is partial failure:
📄️ Data Correctness Across UI + DB
Many “bugs” are correctness failures:
📄️ Fullstack Security for Seniors
Senior engineers don’t “add security.”
📄️ Case Study: Auth & Sessions
Auth is not “login.”
📄️ Case Study: Feed Page (SSR vs ISR vs CSR)
A “feed page” looks like UI work.
📄️ Case Study: Payments & Checkout
Payments failures are rarely “bugs.”
📄️ Case Study: Realtime Notifications
Realtime features fail in predictable ways:
📄️ Case Study: Search + Filtering
Search systems fail when teams treat them as “just an endpoint.”
📄️ Case Study: Multi-Tenant SaaS
Multi-tenancy failures are usually boundary failures:
