React react applications.

Modern React applications with Next.js App Router, server components, type-safe data fetching, and component libraries that scale past fifty screens without rotting. Built for Web Vitals scores you can defend.

Overview

What it means to work with us.

React is everywhere, but well-built React is rare because the framework asks for taste and the ecosystem rewards new patterns weekly. We focus on the boring fundamentals — server components for speed, suspense for loading states, TanStack Query for data, and component libraries documented in Storybook — that hold up over years.

What we deliver

Capabilities & deliverables.

Every engagement is shaped to fit, but these are the building blocks we rely on.

01

Next.js App Router

Server components, ISR, route handlers, and edge functions used where they actually pay off. We measure before we adopt the latest pattern.

02

Component Libraries

Storybook-driven, accessible by default, and themable across multiple products. Owned by you, extensible by your team.

03

Type-Safe Data Layer

tRPC, GraphQL Codegen, or end-to-end TypeScript with Zod validation. Bugs caught at compile time, not in production.

04

Animation That Behaves

Framer Motion or GSAP, applied with restraint. Transitions are perceptual cues, never decoration that costs frame budget.

05

Real-Time Features

WebSockets, Server-Sent Events, and optimistic updates wired through TanStack Query. UI feels instant, server stays correct.

06

Audits & Migrations

Legacy CRA to Vite, class components to hooks, page directory to App Router. Refactored in stages, with tests pinning each step.

Why it works

The SD Technolabs difference.

Two decades of practice sharpened into a way of working that respects both craft and clock.

01

Type-safe end to end

TypeScript strict, Zod for runtime validation. Refactors that would scare a JS team take an afternoon and a green test run.

02

Performance budgets enforced

Bundle size, LCP, CLS, and TBT tracked per PR. Regressions block merges; you find out in code review, not after launch.

03

Patterns that scale

We know which React patterns survive 50 components and which collapse. Context boundaries, suspense graphs, server-client splits — all considered.

04

Accessibility as design constraint

Keyboard navigation, focus management, and screen-reader semantics are part of the brief, not a phase three afterthought.
