Custom applications

When no platform fits, we write the application.

Next.js, React and PostgreSQL for the products, CMSs, portals and internal tools that WordPress, Webflow and Shopify cannot carry — built in your repository, run by the team that wrote them, and boring by design so that someone else could maintain them.

What we build from scratch

Four kinds of work.

Most engagements start with one and grow into the rest.

01

Custom CMS

An editorial backend shaped like your content rather than a generic admin: the fields you actually publish, a preview that renders exactly what the site renders, and pages refreshed the moment you hit publish. This site runs on one.

  • —Content model designed around your editors
  • —Markdown or block editor with live preview
  • —Media, tags, drafts and scheduling
  • —One record per language, paired for hreflang
  • —Revalidation on publish, no redeploy
02

Web apps and SaaS

Multi-tenant products with accounts, plans and billing — the shape of WelcomeAI, which serves its workspace, marketing site, widget and admin console from one Next.js codebase.

  • —Tenant isolation in the data model
  • —Auth, roles and session revocation
  • —Plans, quotas and billing
  • —Background jobs that report per item
  • —Embeddable widgets and public APIs
03

Internal tools and client portals

The back office, the CRM, the portal a client signs into — for when the spreadsheet stopped being enough and the off-the-shelf tool wants you to change how you work. Our own CRM runs on the same stack and the same deployment as this site.

  • —Permissions decided in one module, applied everywhere
  • —Client logins scoped to their own work
  • —Time tracking, files and share links
  • —Private file storage behind the same check
  • —One deployment for the site and the tool
04

Custom integrations and APIs

Your own endpoints, webhooks and middleware between the application and everything around it — the same queue-and-reconciler shape as our integrations work, in a codebase that is yours.

  • —REST endpoints and signed webhooks
  • —Third-party APIs behind one typed client
  • —Queues, retries and a nightly reconciler
  • —Transactional email from your own domain
  • —Model and map providers set by variable, not in code
How we work

Your repository. Your database.
Our responsibility.

Deliverable

One code path, wherever it runs

Local and production run the same code against the same database engine, the migrations ship inside the deployment, and nothing branches on environment — so what was tested is what goes live. That is how this site is built, and how yours would be.

Boring technology, on purpose

Next.js, React, TypeScript and PostgreSQL: mature, documented and hireable. Choosing them is choosing a stack that someone other than us can maintain in five years, which is the whole point of custom code you own.

The platform question comes first

If WordPress, Webflow or Shopify can carry the product, we say so and build it there. Custom code is for when the constraint is real — a data model, a tenant boundary, a performance budget — not for when it sounds impressive.

We run what we build

Our own products are on this stack and in production. The migrations, the monitoring and the on-call habits come from operating them, and your application inherits them on day one.

Outgrown every platform?

Tell us what it has to do and who has to maintain it. We'll tell you whether it needs custom code — and what it takes if it does.

No commitment. Just a conversation.
