49 guides
01

03

Accessibility Engineering: Building Interfaces Everyone Can Use

Implement web accessibility (a11y) as an engineering practice, not an afterthought. Covers WCAG compliance, semantic HTML, keyboard navigation, screen reader testing, ARIA patterns, color contrast, and the automated testing that catches 30% of issues before manual review catches the rest.

04

React Performance Optimization: From Slow Renders to 60fps

Optimize React application performance with techniques that eliminate unnecessary re-renders, reduce bundle size, and deliver a smooth 60fps user experience. Covers React.memo, useMemo, useCallback, code splitting, virtualization, profiling, and the mental model for understanding when and why React re-renders.

05

Organize CSS for large applications using proven methodologies like BEM, ITCSS, and utility-first approaches. Covers naming conventions, CSS custom properties, scoping strategies, specificity management, and migration paths from CSS chaos to maintainable stylesheets.

09

Web Performance Optimization

Optimize web application performance using Core Web Vitals as a framework. Covers LCP, FID, CLS optimization, bundle analysis, lazy loading, image optimization, and the performance budget that keeps your app fast as it grows.

10

State Management Patterns

Choose and implement the right state management pattern for your frontend application. Covers local state, lifted state, context, external stores (Redux, Zustand, Jotai), server state management, and when each approach makes sense.

11

Design System Engineering

Build and maintain a design system that scales across teams, products, and platforms. Covers component API design, token architecture, documentation-driven development, versioning, and adoption strategies.

12

Accessibility Engineering

Build accessible web applications that work for everyone. Covers WCAG compliance, semantic HTML, ARIA patterns, keyboard navigation, screen reader testing, and making accessibility a first-class engineering concern.

13

Web Component Architecture

Build reusable, framework-agnostic UI components using native Web Components. Covers Custom Elements, Shadow DOM, HTML templates, slots, lifecycle callbacks, and the patterns that make Web Components work alongside React, Vue, and Angular.

14

Core Web Vitals Optimization

Optimize the three Core Web Vitals that Google uses for search ranking and user experience. Covers Largest Contentful Paint, Cumulative Layout Shift, Interaction to Next Paint, measurement tools, and the performance engineering patterns that deliver fast, stable, responsive pages.

15

Design Tokens

Create a single source of truth for design decisions that powers every platform and framework. Covers token taxonomy, naming conventions, transformation pipelines, multi-platform distribution, theming, and the patterns that bridge design and engineering.

16

Server-Side Rendering Strategies

Choose and implement the right rendering strategy for performance and SEO. Covers SSR, SSG, ISR, streaming SSR, edge rendering, hydration patterns, and the patterns that deliver fast, SEO-friendly web applications.

17

Internationalization Engineering

Build applications that work across languages, locales, and cultures. Covers i18n architecture, Unicode handling, RTL support, date/number formatting, translation management, and the patterns that prevent localization from becoming a retrofitting nightmare.

18

Micro-Frontend Architecture

Decompose monolithic frontends into independently deployable units. Covers composition patterns, module federation, shared state management, and the patterns that let multiple teams ship frontend features independently.

19

CSS Container Queries

Build truly responsive components that adapt to their container size, not just the viewport. Covers container query syntax, use cases vs media queries, component-driven responsive design, and the patterns that make components reusable across any layout context.

20

Frontend State Machine Patterns

Model complex UI state with finite state machines. Covers XState fundamentals, statechart theory, managing multi-step forms, modal flows, and the patterns that eliminate impossible states by making valid transitions explicit.

21

Web Animation Performance

Build smooth 60fps animations that don't jank. Covers CSS animations vs. JavaScript, compositor-only properties, requestAnimationFrame, FLIP technique, and the patterns that keep animations fluid on every device.
