Websites & Web Apps

Websites and apps that win customers and run your operations

We design and build websites, custom web apps, client portals and iOS and Android apps. Every build is fast, accessible, search-ready and wired into the tools your team already uses.

Who it's for

For service businesses replacing an outdated site, and for companies that need a portal, dashboard or mobile app their customers will actually use.

The problem

Sound familiar?

Your website looks dated and converts poorly

Visitors leave before they call. The site is slow on mobile, hard to update and does not explain why you are the right choice.

Work lives in spreadsheets and chat threads

Customers ask for updates by phone and WhatsApp because there is no single place to see progress, documents and invoices.

Previous developers left you stuck

No documentation, no access to the code, and every small change becomes a new quote.

FAQ

Websites & Web Apps questions

How long does a new website take?

A business website usually takes 3 to 6 weeks from kickoff to launch. Custom web apps and portals typically take 6 to 12 weeks, depending on integrations.

Do I own the code and design?

Yes. You receive the full source code, design files and admin access at handover. Ownership is written into every agreement.

Can you build the mobile app too?

Yes. Mobile apps for iOS and Android are part of this service, usually built with React Native or Flutter so one codebase serves both stores.

Will I be able to edit the site myself?

Yes. We set up a content editor for pages, posts and services, and record a short training video for your team.

What happens after launch?

Every build includes a post-launch support window. After that you can move to a monthly support plan or take the project in-house with our documentation.
