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.
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.
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.
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
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.
Rendering & edge
Where and how HTML is produced
UI & design system
Consistent, accessible interface
State & data fetching
Keeping the client in sync
API / BFF layer
A clean seam to the backend
Auth & sessions
Who is allowed to do what
Observability
Knowing what real users experience
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.
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.
From prototype to production.
We show working software early and improve it in the open, so there are no surprises at launch.
Prototype
A clickable, real-data prototype to validate before we scale.
Build on a design system
Components and tokens so the UI stays consistent as it grows.
Integrate & secure
Wire in APIs, auth and data with clean, tested contracts.
Performance & a11y pass
Tune Core Web Vitals and accessibility to budget.
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.
