Web apps that stay fast
as the feature list grows.

Next.js and React front ends on Postgres, typed end to end, with auth, roles and billing done properly the first time. So feature forty ships as fast as feature four.

What it is

What web app development actually involves

Any team can ship the first version of a web app. The question is what the tenth feature costs. That number is set early, by whether auth and permissions were modelled properly, whether the database schema matches the domain, and whether anyone can tell what broke in production.

We build the boring foundations first because retrofitting them is where budgets go. Roles and permissions, billing, audit trails, error tracking and a typed contract between the database and the interface, so a change in one place fails at build time rather than in front of a customer.

What we build

From schema to interface, one crew.

The seams that usually rot are the same person's problem here.

Product front ends

Next.js or React with a real design system, accessible components and Core Web Vitals green before launch.

Auth and permissions

Sessions, SSO, roles and row-level isolation modelled at the start, because bolting it on later means touching every query.

Billing

Subscriptions, trials, upgrades, proration and dunning, so you can take money on launch day and keep taking it.

Dense data interfaces

Tables, filters, charts and exports that stay readable and do not fall over at a hundred thousand rows.

APIs and integrations

Typed APIs, webhooks with retries, and the third-party integrations your customers keep asking for.

Observability

Error tracking, structured logs and product analytics wired at launch, so you find out from a dashboard rather than a customer.

Common questions

Web app questions we get first.

Not answered here? Email us. A real reply from an engineer, no form.

Why Next.js?

It covers server rendering, routing and API handlers in one framework your next hire has probably used. If your team already runs Remix, Rails or Django, we work in that instead. The framework matters less than the foundations.

Can you work with our existing codebase?

Usually yes. We start with a short audit, then tell you what is worth keeping and what is cheaper to replace. If a rebuild is the honest answer, we say so before you spend money finding out.

How do you handle multi-tenancy?

Row-level isolation from day one, plus SSO, audit exports and role granularity. That is the checklist enterprise security reviews actually run, and retrofitting it later means rewriting every query.

What about performance?

Core Web Vitals green at launch is part of the definition of done, not a follow-up ticket. Beyond that, the usual wins are query shape and caching, which is why one crew owns both the schema and the interface.

What does a web app cost?

It depends on the surface area, which is why the scoping call comes first. We quote one fixed figure and hold it, and we will tell you if what you want does not fit your budget.
