Web Application Development
for Mid-Market Enterprises

Mid-market teams no longer need to choose between shipping fast and building right. We deliver responsive, accessible web applications on a modern React and Node stack — server-rendered where it matters for SEO, measured against Core Web Vitals rather than a designer's screenshot, and handed over with the tests and documentation your team needs to keep moving after we leave.

The problem

Most sites are measured on a screenshot

It looks right in the review, on a fast connection, on a large screen. Then it ships — and the pages are slow on a phone, the search rankings drop because content renders client-side, and nobody can change anything without the agency that built it.

Core Web Vitalsas a budget

Rendered socrawlers see it

Handed overwith tests

Measured, not assumed.Yours to maintain.

Performance

is a revenue number

Every additional second before a page becomes usable costs conversions, and mobile users on real networks feel it long before your team does.

Client-side only

costs you search visibility

If meaningful content arrives after JavaScript executes, crawlers and link previews frequently see an empty shell instead of your page.

Our fix

measure it, then hand it over

Server-rendered where it matters, held to a performance budget in CI, and delivered with the tests and docs your team needs to keep shipping.

HOW WE DO

Progressive Web Apps

Service workers and an app manifest, so the app installs to a home screen and keeps working on a patchy connection. Useful where staff are on the move rather than at a desk.

Responsive Design

Layouts built mobile-first and checked on real phones and tablets, not just a browser window dragged narrow. Touch targets, wrapping tables and long-form content all get tested.

High Performance

Core Web Vitals treated as a budget enforced in CI, with code splitting, image sizing and caching headers doing the work. A page that regresses fails the build.

Modern Frameworks

React and Next.js on the front end, Node.js behind it, chosen because your team can hire for them. Server rendering where SEO and first load matter, client rendering where interaction does.

API Integration

REST and GraphQL integrations with your CRM, payment and ERP systems, built with retries, timeouts and error handling so a third-party outage degrades gracefully instead of breaking a checkout.

Custom UI/UX

Interfaces built from a component library with every state specified, including error, empty and loading, and keyboard and contrast behaviour tested against WCAG 2.2 AA.

Backend Development

Node.js services with schema-validated inputs, indexed queries and sensible caching, so the database survives a traffic spike rather than becoming the bottleneck under it.

Fast Deployment

CI/CD pipelines that run tests, accessibility checks and performance budgets on every commit, then deploy to preview and production. Rollback is one step, not an incident.

Real-time Features

WebSocket and server-sent event channels for live chat, notifications and dashboards, with reconnection and offline queueing handled so a dropped connection doesn't lose a message.

What changes

Outcomes we hold ourselves to

Every engagement starts by agreeing which of these numbers we're moving, and how we'll measure it. Ranges below reflect what our web engagements have delivered — your starting point determines where you land.

< 2.5s

largest contentful paint

The Core Web Vitals threshold, measured on mid-range mobile hardware over a realistic connection rather than a desktop on office wifi.

Server-rendered

so crawlers see your content

Meaningful HTML in the initial response, which is what search engines and link previews actually index.

WCAG 2.2 AA

as acceptance criteria

Keyboard paths, focus states and contrast tested as part of delivery, not audited as a remediation project afterwards.

In your repo

with tests and a pipeline

Handed over so your team can change the site without needing us — the alternative is a dependency you didn't ask for.

How we work

Three ways to start

The right shape depends on whether you're fixing a site that underperforms, building something new, or running a continuous roadmap. Moving between them is normal.

Scoped build

For a defined site or application with agreed scope and a launch date.

  • Performance budget enforced in CI, not checked once before launch
  • Integrations with the CMS, CRM and payment tools you already run
  • Full handover — code, tests, pipeline and documentation

Timeline

8–20 weeks, fixed scope

Best for

A known, bounded build

Trust & compliance

Built to survive an audit

A public web application is the part of your business anyone can probe, and accessibility is a legal requirement in most markets our clients sell into. Both are designed for from the first sprint.

Aligned to

GDPR
WCAG 2.2 AA
OWASP Top 10
SOC 2
PCI DSS

Secure by default

Authentication, session handling and input validation built to OWASP guidance, with dependency scanning in the pipeline rather than an annual review.

Accessibility as a requirement

Built and tested against WCAG 2.2 AA, with automated checks in CI and manual keyboard and screen-reader passes before release.

Consent handled honestly

Analytics and marketing tags gated behind genuine consent, so tracking doesn't start before a visitor has agreed to it.

Your infrastructure, your data

Hosting in your accounts and chosen region, with the code in your repositories from the first commit rather than transferred at the end.

Usually yes, and often you should — content teams having to relearn a tool is a real cost that rarely appears in a project plan. We frequently keep an existing CMS and replace the front end, which gets you the performance and accessibility gains without retraining anyone. If the CMS itself is the bottleneck, we'll make that case with specifics rather than as a preference.

It can, and it's the most commonly overlooked risk in a rebuild. Rankings drop when URLs change without redirects, when metadata is lost, or when content moves to client-side rendering. We map redirects before launch, keep meaningful content server-rendered, and benchmark beforehand so you can see the actual effect rather than guess at it.

Most business sites are better served by server rendering, because search visibility and first-load speed matter more than in-app navigation. Rich, logged-in application interfaces are the genuine case for heavier client-side rendering. Plenty of projects sensibly use both — a fast public site and an app-like authenticated area.

The code, tests, pipeline and documentation are yours, in your repositories, so your team can keep shipping. Many clients keep us on a retainer for dependency updates, performance work and new features — worth knowing that a site left entirely untouched for a year accumulates security exposure through its dependencies, whoever handles it.

By making performance a budget rather than a launch-day achievement. Thresholds are enforced in CI, so a page that gets slower fails the build in the same way a broken test would. Without that, sites reliably degrade — usually through images and third-party marketing scripts nobody re-measured after adding.
