Web Application Development

A customer-facing web product built to carry a roadmap, not a prototype dressed up for launch day.

from €7,900

The Problem

The current front end can't carry where the product needs to go. Either it's a prototype wearing production clothes — fast to demo, expensive to extend — or it's aging technology that turns every new feature into a fight with the codebase underneath it.

  • Every new feature takes longer than the last one, on the same-sized team
  • The front end was built to close a deal, not to be maintained for years
  • Design and engineering disagree about what's actually possible to ship

What's Included

An architecture chosen for your actual roadmap

not the framework that was trending when the first version was built.

A component system, not a page-by-page build

new screens reuse what already exists instead of duplicating it.

Performance and accessibility treated as requirements

not a pass at the end.

API contracts written down

your backend team (or ours) knows exactly what the front end expects.

A deployment pipeline

not a manual release process.

Full source, transferred on final payment.

Who It's For

Perfect for

  • Product leads whose current front end is slowing every release
  • Founders with an idea that outgrew a landing-page builder or no-code tool
  • Teams doing a partial rebuild — just the front end, with an existing backend to keep

Outcomes

  • New features ship in weeks, not quarters, because the architecture supports them
  • A product that reads as production-grade to a customer or an investor
  • A codebase the next engineer you hire can actually work in

Packages

TIER 01

Frontend Rebuild

The interface rebuilt on a modern architecture, backend untouched.

from €7,900

→ 4–6 weeks · starts within 2 weeks

  • Audit of the current front end and the API contracts it depends on
  • Rebuild on a component-based architecture (React/Next.js by default)
  • Responsive layout, accessibility pass to WCAG 2.2 AA
  • Integration against your existing backend/API, unchanged
  • Deployment pipeline and documentation
  • Backend changes (scoped separately if the API itself needs work).

BEST FOR Products with a solid backend held back by a front end that can't keep up.

Most chosen

TIER 02

Web App Build

The full product — front end and back end — built from a written specification.

from €18,900

→ 8–12 weeks · starts within 3 weeks

  • Specification covering data model, API design and front-end architecture
  • Full build in weekly increments, weekly working demos
  • Authentication, role handling, and the core feature set defined in the spec
  • Deployment pipeline, staging and production environments
  • Source, documentation and credentials, transferred on final payment
  • 30 days of post-handover bug-fix cover

BEST FOR A product being built or substantially rebuilt from the ground up.

TIER 03

Full Product Build

A larger product surface — multiple user roles, integrations, and a longer build horizon.

from €32,000

→ 14+ weeks · starts within 4 weeks

  • Everything in Web App Build, scoped for multi-role/multi-module products
  • Third-party integrations (payments, email, analytics) as specified
  • A phased delivery plan with demo milestones, not one single release at the end
  • Post-launch support window (defined in the specification), source transferred on final payment

BEST FOR Products with real complexity — multiple roles, integrations, a company depending on the launch date.

How This Engagement Runs

Survey

We review the current product (if one exists) and the roadmap it needs to support for the next 12–18 months, not just the next release.

Specification

Architecture, data model and API contracts are written down and priced before a line of front-end code is written.

Build

Weekly increments, each ending in a working, clickable demo — not a static design file.

Verification

Functional testing against the specification, plus a performance and accessibility pass.

Handover

Full source, deployment credentials and documentation transfer on final payment.

Frequently asked

Can you keep our existing backend and only rebuild the front end?
Yes — that's exactly what Frontend Rebuild is for. We audit the current API contracts first so the new front end integrates cleanly.
What if we don't have a backend yet?
Web App Build and Full Product Build both include backend architecture and development — the specification covers both layers.
Do you use our design, or do we need one first?
Either. If you have a design system, we build against it. If not, a UI/UX & Product Design package upstream of this one is the cleaner sequence — see Related Services below.
What happens after the 30-day bug-fix window?
You own the code outright, so you can maintain it in-house, hire elsewhere, or move to a Maintenance & Support retainer with us — no obligation either way.

A product built to survive its own roadmap.
