Web App Development

We build web applications meant to run in production for years, not demo well for a quarter — from the data model up, with the operational concerns (auth, observability, deploys) treated as core scope, not an afterthought.

Most web apps fail slowly: the first release is fine, then every feature takes longer than the last. We avoid that by settling the hard decisions first — the data model, the auth boundary, the rendering strategy — and writing them down so your team can challenge them before code exists.

On the frontend we build with Next.js and React, using server components where data is heavy and a small client bundle where interaction is real. Accessibility and performance budgets are part of the definition of done, so Core Web Vitals do not become a cleanup project after launch.

Behind it sit PostgreSQL or your existing datastore, typed APIs, and a deploy pipeline with staging environments. You get observability from week one, which means the first production incident is a dashboard, not a mystery.

What's included

Architecture and data-model design reviewed against real access patterns
Frontend built on Next.js/React with full accessibility and performance budgets
CI/CD, staging environments, and observability wired in from week one
Documented handoff — your team can extend it without us in the room

What changes in the codebase

balance.ts

 export async function getBalance(userId: string) {
−  const res = await fetch(`/api/legacy/balance/${userId}`);
−  return res.json(); // no retry, no timeout, no typed shape
+  const res = await client.balances.get(userId, {
+    retry: 3, timeoutMs: 2000,
+  });
+  return BalanceSchema.parse(res);
 }

It depends on scope, integrations, and compliance needs. After a short discovery we give a fixed range for the first release and a time-and-materials model for what follows. We will tell you if a smaller first release gets you to real users faster.

They give us server rendering for SEO and speed, a mature ecosystem, and a large hiring pool for your team later. If another stack fits your constraints better, we say so.

Yes. We start with a short audit covering architecture, test coverage, and deploy safety, then agree a plan to stabilise it before adding features.
