Custom Web App Development

Custom web apps, built full-stack and shipped in weekly increments

We build web applications end to end: interface, API, database, deployment. You work directly with the engineers writing your code, and you see working software every week instead of a status report.

Most of our projects start from a rough idea or an existing product that has become hard to change. Either way we begin by agreeing on the smallest version worth shipping, then build outward from there.

What we deliver

SaaS products

Multi-tenant apps with authentication, roles, subscriptions and billing through Stripe or Paddle.

Dashboards and internal tools

Admin panels, reporting views and workflow tools that replace spreadsheets and manual steps.

APIs and integrations

REST and GraphQL APIs, webhooks, and integrations with the CRMs, payment providers and data sources you already use.

Rescue and modernization

Taking over a codebase that has stalled: audit, stabilize, add tests, then migrate piece by piece.

Technology we use

  • TypeScript
  • React
  • Next.js
  • Node.js
  • NestJS
  • PostgreSQL
  • Prisma
  • Tailwind CSS
  • AWS
  • Vercel

A good fit if

  • You have a defined problem and need a team to build the product around it
  • You want direct access to engineers, without account managers in between
  • You need to own the code, the repository and the infrastructure from day one

How a project runs

  1. Step 1

    Project brief

    You send us a description of the problem, the users and the constraints. We reply in writing with questions within one working day.

  2. Step 2

    Written estimate

    Within a few working days you receive a scope, a timeline and a price broken down by feature.

  3. Step 3

    Weekly increments

    We build in one-week cycles. Each ends with a recorded demo and a version you can open and test yourself.

  4. Step 4

    Launch and handover

    We deploy to your accounts, document the system and either stay on for maintenance or hand over to your team.

Frequently asked questions

How much does a custom web app cost?

It depends on scope. Once we understand your requirements we send a written estimate broken down by feature, so you can see what each part costs and cut what you do not need. We do not start work before you have approved that estimate.

How long does it take to build a web app?

A focused first version usually takes between six and twelve weeks. Larger products are split into phases so that something usable ships early and the rest follows in increments.

Who owns the source code?

You do. Code lives in a repository under your account, and infrastructure is provisioned in your cloud accounts. Full ownership transfers on payment of each invoice.

Can you work with our existing team or codebase?

Yes. We regularly join existing teams, follow their conventions and review process, and take on a defined part of the roadmap.

How do we communicate across time zones?

We work in written English. You get an update at the end of every working day and a recorded demo every week, so you can review progress at any hour. Questions are answered within one working day.
