Modern Web Technologies

High-Performance Web Applications with TypeScript, React, and Next.js

Build lightning-fast, SEO-optimized web experiences that convert. Our modern stack delivers 89% Core Web Vitals compliance, 2% conversion lift per second saved, and 40% lower maintenance costs.

Intro

Web performance directly impacts revenue. Research shows that 2-second page loads convert at 15%, while 5-second loads drop to 7%. Every 100ms delay costs you customers, trust, and competitive positioning.

The TypeScript/React/Next.js stack eliminates legacy bottlenecks that sabotage conversion rates. TypeScript catches 15% of bugs before deployment. React's component architecture cuts development time by 40%. Next.js delivers automatic code splitting, image optimization, and server-side rendering that make slow sites structurally impossible.

WAYF has delivered 100+ web applications over 10 years using this stack. We architect for Core Web Vitals from day one, ensuring your site loads fast, ranks high in search results, and converts traffic into revenue. Whether you're building SaaS platforms, e-commerce experiences, or content-heavy sites, we deliver performance that compounds your marketing spend

Why TypeScript, React & Next.js?

Developer Experience = Faster Delivery

Fast Refresh preserves component state during development, eliminating refresh cycles. TypeScript autocomplete accelerates coding. React DevTools provide visibility into component behavior. Next.js's intuitive routing eliminates configuration overhead. These efficiency gains compound—most teams report 30-40% faster development velocity versus older stacks.

Write your app logic once and deploy to both iOS and Android simultaneously. React Native shares 70-90% of code across platforms, dramatically reducing development time and maintenance overhead while ensuring feature parity. Your team moves faster, your users get consistent experiences, and your budget stretches further.

TypeScript: Code That Doesn't Break

JavaScript's flexibility causes production bugs that cost time and money. TypeScript adds compile-time type checking that catches errors before they reach users. Studies show TypeScript reduces bugs by 15-20%, prevents entire categories of runtime errors, and makes refactoring safe. Your codebase becomes self-documenting, easier to maintain, and more attractive to senior engineers.

React: Component Architecture That Scales

React's component model revolutionized web development for good reason. Reusable UI components accelerate development by 40%, enable consistent design systems, and make A/B testing straightforward. The virtual DOM ensures efficient updates, maintaining 60fps even with complex interactions. With 16 million weekly npm downloads, React has the largest ecosystem and talent pool of any frontend framework.

Next.js: Performance by Default

Next.js transforms React from a library into a full-featured framework with built-in solutions for the hard problems: server-side rendering for fast initial loads, automatic code splitting that sends minimal JavaScript, image optimization that serves WebP/AVIF formats, API routes for backend logic, and ISR (Incremental Static Regeneration) that combines static speed with dynamic content. Sites built with Next.js consistently achieve 89%+ Core Web Vitals compliance versus 40% industry average.

SEO That Actually Works

Single-page applications historically struggled with SEO. Next.js solves this with server-side rendering and static generation, ensuring search engines see fully-rendered content. Combined with automatic sitemap generation, metadata optimization, and structured data support, Next.js sites rank higher and capture more organic traffic. Your content marketing investment compounds instead of getting buried.

Ideal Use Cases

E-Commerce Platforms

E-Commerce Platforms

Fast page loads directly impact conversion rates—every 100ms delay costs 1% of sales. Next.js's automatic optimization delivers sub-2-second page loads even with hundreds of products. Server-side rendering ensures product pages rank in search results, while ISR keeps inventory accurate without constant rebuilds.

SaaS Applications

SaaS Applications

Dashboard-heavy applications need responsive interfaces and complex state management. React's component architecture handles intricate UIs while maintaining performance. TypeScript prevents the bugs that plague large codebases. Next.js API routes enable rapid backend prototyping without managing separate services.

Content Publishing & Blogs

E-Commerce & Retail

Media sites live or die by SEO rankings and ad revenue. Next.js's static generation delivers blazing-fast article loads that improve Core Web Vitals, directly boosting search rankings. Headless CMS integration gives editors flexibility while developers maintain performance control.

Marketing Websites

Marketing Websites

Lead generation requires fast loads, perfect mobile experiences, and top search rankings. Next.js achieves 95+ Lighthouse scores out of the box, ensures mobile responsiveness, and generates static pages that rank immediately. Your marketing spend converts better because the landing experience doesn't sabotage campaigns.

Customer Portals

FinTech & Banking

Authenticated experiences need security, personalization, and reliability. Next.js's middleware handles authentication routing, React manages complex permission-based UI states, and TypeScript ensures data consistency across user roles. Scale from hundreds to millions of users without architectural rewrites.

Progressive Web Apps (PWAs)

Progressive Web Apps (PWAs)

Mobile users expect app-like experiences without installing anything. Next.js PWA support enables offline functionality, home screen installation, and push notifications. Users get native-feeling experiences while you maintain a single codebase instead of separate iOS/Android apps.
