Application Development // Responsive Frontends
Best for any firm with web apps used outside the office

Web apps that work on every screen — and feel like they belong.

Most enterprise web apps look like they were designed for IE7. Tiny tap targets, broken on mobile, awkward on tablets, slow everywhere. We build frontends that work — and feel right — across phones, tablets, laptops, and the giant monitor in the boardroom.

Sound familiar?

How most enterprise web apps fail on phones.

pain 01

Buttons too small to tap.

Designed for a mouse. Tap-and-zoom to hit anything. Users give up.

pain 02

Layout breaks at certain sizes.

Looks fine on the developer's laptop. Garbled on the sales team's iPads. Useless on phones.

pain 03

Forms are unfillable on mobile.

Tiny labels, wrong keyboard types, no autocomplete. Customers abandon before submitting.

pain 04

Slow on anything except a fast connection.

3 MB JavaScript bundle. Loads OK in the office. Times out on the train.

What you get

How we build frontends.

  • 01

    Mobile-first design

    Designed for phone first. Scales up to tablet, laptop, desktop. Not the other way around.

  • 02

    Real device testing

    We test on actual phones (iOS + Android, current + older models), not just browser emulators.

  • 03

    Accessibility built in

    WCAG 2.1 AA standard. Keyboard navigation, screen reader compatible, color contrast checked.

  • 04

    Performance budgets

    Target page weight + load time per route. Enforced in CI. No surprise slowdowns over time.

  • 05

    Design system

    Reusable components. Consistent look across the app. Easier to maintain, easier to extend.

  • 06

    Modern tooling

    React or Vue + TypeScript + Tailwind. Mature, hireable stack. Not framework-of-the-week.

From a client
Our internal app worked on desktop. Sales team complained constantly — they live on iPads. Senator rebuilt the frontend over 12 weeks. Same backend. Now sales actually uses it. Adoption tripled.

  • Anyone with sales, field, or customer-facing users on phones and tablets.
  • Firms subject to accessibility requirements (public sector, regulated industries, AODA in Ontario).
  • Anyone whose users complain about slow load times.
FAQ
Q01

Can we keep our existing backend?

Yes — we rebuild only the frontend. Existing APIs stay. Backend team isn't disrupted.

Q02

What about our brand and visual style?

Yours, fully respected. We work with your designer (or partner with one) to translate brand into a design system.

Q03

Do you do native mobile apps too?

Selectively — React Native or Swift/Kotlin when truly needed. Often a responsive web app is the better answer.

Q04

How long does a frontend rebuild take?

Small app: 6–10 weeks. Mid-sized: 12–24 weeks. Large enterprise: phased over 6–12 months.
