# Accessible Web Development

> Modern web products, accessible and secure from day one.

We build fast, modern web applications where accessibility and security aren't bolted on - they're designed in. Semantic, performant, WCAG-conformant front-ends backed by secure engineering practices.

## Outcomes

- WCAG 2.2 conformant from the first commit
- Performance-first, Core Web Vitals optimized
- Secure engineering and dependency hygiene
- Reusable accessible component systems

## Process

01. **Discover** - Goals, users, accessibility and security requirements.
02. **Design** - Inclusive UX and an accessible design system.
03. **Build** - Performant, secure, conformant implementation.
04. **Verify** - Accessibility, performance and security testing before launch.

## Deliverables

- Production web application
- Accessible design system / component library
- Performance & accessibility reports
- Documentation and handover

## Standards

WCAG 2.2, Core Web Vitals, OWASP ASVS


## Overview

Modern web applications must be both accessible and secure by design, not as an afterthought. We build performant, responsive web interfaces on React/Next.js stacks where WCAG 2.2 AA compliance and OWASP secure-coding practices are baked in from the very first commit.

Our engineering team combines modern front-end frameworks with rigorous accessibility testing and dependency auditing. We deliver high-speed web apps optimized for Core Web Vitals, featuring semantic HTML, robust ARIA widgets, keyboard operability, and strict input sanitization.


## What we cover

### Semantic Components
Building interactive widgets using accessible semantic structures and strict focus control.

### Performance Tuning
Optimizing Core Web Vitals (LCP, INP, CLS) through code splitting, asset optimization, and caching.

### Secure APIs & Inputs
Implementing CORS policies, sanitizing user inputs, and securing dynamic state variables.

### Automated Accessibility CI
Integrating Axe-core and ESLint-plugin-jsx-a11y checks directly into compilation scripts.

### Responsive Layouts
Testing reflow and viewport flexibility down to 320px to prevent horizontal scrolling.

### Dynamic Themes & Contrast
Building light/dark mode architectures using variables that satisfy contrast rules.


## FAQ

**What stack do you build on?**
Modern React/Next.js front-ends by default, with the back-end chosen to fit your needs. Accessibility and security are constant.
