Web apps that feel instant.

Users judge a web app in milliseconds and abandon whatever is slow or inaccessible, which makes performance and accessibility product features rather than polish. We engineer product apps, portals and SaaS front-ends that are fast, accessible and built to convert.

The modern bar

Fast and accessible, or invisible.

The floor for a web app has risen. Meeting it is table stakes; missing it quietly costs you users and search visibility every day.

Why it matters

Core Web Vitals and accessibility are ranking and conversion factors now — not finishing touches. A slow or inaccessible app loses users before it loads and loses search visibility on top. Speed and inclusivity are the product, measured in real numbers, not a phase you tack on at the end.

The key decision

Server, static, or client?

How a page is rendered decides its SEO, its freshness and how fast it feels. We pick per route rather than betting the whole app on one strategy.

Server-rendered (SSR/streaming)

Best for: Dynamic product apps

  • Fresh, personalised HTML per request
  • Strong SEO out of the box
  • Fast first paint via streaming
  • Needs real server infrastructure

Static & ISR (SSG)

Best for: Content & marketing

  • Served from the edge, near-instant TTFB
  • Cheapest and most resilient
  • Revalidates on a schedule
  • Not for per-user, real-time data

Client SPA

Best for: App-like internal tools

  • Rich, app-like interactivity
  • Backend can be a plain API
  • Weaker SEO without extra work
  • Heavier initial load to manage
Under the hood

Web application architecture.

A modern front-end is a system: rendering, data, auth and observability all have to fit together. These are the layers we design and harden.

What we build

Front-ends people trust.

Interfaces where the interaction is the product — not brochure sites, but the apps your customers and teams use every day.

Product apps

The core interface your users spend real time inside.

Customer & partner portals

Secure self-service that cuts support load.

SaaS dashboards

Dense, responsive data views that stay fast.

Design systems

A shared component library that keeps you consistent.

Progressive web apps

Installable, offline-capable web with app-like feel.

Headless / commerce front-ends

Fast storefronts on a decoupled, API-first stack.

Engineered in

Quality that isn't optional.

These are not extras we quote separately — they are how we build, checked in CI on every change.

Core Web Vitals budgets

Performance targets enforced, not aspired to.

Accessibility (WCAG 2.2 AA)

Semantic, keyboard-navigable, screen-reader tested.

SEO & GEO ready

Real HTML, structured data and AI-answer visibility.

Security (OWASP)

Input validation, safe auth and dependency scanning.

Resilience & error handling

Graceful degradation and boundaries that contain failure.

Automated testing

Unit, integration and end-to-end coverage in the pipeline.

How we deliver

From prototype to production.

We show working software early and improve it in the open, so there are no surprises at launch.

01

Prototype

A clickable, real-data prototype to validate before we scale.

02

Build on a design system

Components and tokens so the UI stays consistent as it grows.

03

Integrate & secure

Wire in APIs, auth and data with clean, tested contracts.

04

Performance & a11y pass

Tune Core Web Vitals and accessibility to budget.

05

Ship & monitor

Deploy, then watch real-user metrics and iterate.

Questions a CTO asks.

Which framework do you use?+

React with Next.js is our default for product apps, backed by TypeScript throughout. It gives us server rendering, streaming and the edge when we need them, without locking you into a niche. We choose the rendering strategy per route rather than dogmatically.

Is it SEO-friendly?+

Yes — and increasingly GEO-friendly for AI answer engines too. We server-render or statically generate content routes so crawlers and models see real HTML, add structured data and clean metadata, and keep Core Web Vitals inside budget, since speed is itself a ranking factor.

Do you handle accessibility?+

Accessibility is built in, not audited at the end. We target WCAG 2.2 AA — semantic markup, keyboard paths, focus management, colour contrast and screen-reader testing — because an inaccessible app loses users and, in many markets, carries legal risk.

Can it integrate with our backend?+

Yes. We connect to whatever you have — REST or GraphQL APIs, existing services, auth providers and third-party systems — often via a thin backend-for-frontend layer that keeps the client simple and the contracts clean.

Do you design too?+

We do. Most engagements run design and engineering together, building on a shared design system so what gets prototyped is what ships. If you already have designers, we integrate with your system rather than replacing it.
