Production-style electronics store for phones, tablets, TVs, and consoles — catalog browsing with variants and filters, guest and registered checkout via PayPal sandbox, admin panel for products/orders/users, installable PWA with web push, SEO for crawlers, and ATDD with Playwright + Vitest. Modernized from a 2021 Udemy exercise to a 2026 portfolio centerpiece on MongoDB Atlas and Render.
Live electronics e-commerce with ~170 products, PayPal checkout, admin ops, installable PWA, and 100+ automated tests.
