Web App Development

Product engineering for tools that carry real load.

When a spreadsheet stops scaling, or a manual process becomes the bottleneck, you need real software. We build web applications on a deliberately unexciting stack — Next.js, Node, Postgres or Mongo — with auth, roles, tests and CI from the first sprint, so the thing still works when your team doubles.

What this typically produces

8-14 wks
MVP delivery window

Scoped to a genuinely minimum first release.

Over 70%
Test coverage at handover

On business logic and critical paths.

2 weeks
Sprint cadence

Demo, retro and a re-prioritised backlog every cycle.

What is included

Everything in a Web Apps engagement

No line items held back for an upsell conversation later.

  • Product discovery & scoping

    User stories, flows and a ruthless MVP cut that ships something usable instead of something impressive on paper.

  • Architecture & data modelling

    Schema design, API contracts and infrastructure choices documented before code, not reverse-engineered after.

  • Full-stack application build

    Next.js or React front end, Node and Express or serverless API, Postgres or MongoDB, deployed on managed infrastructure.

  • Auth, roles & billing

    Secure authentication, granular role-based access and Stripe billing wired to your plan structure.

  • Third-party integrations

    CRM, ERP, payment and messaging integrations with retries, idempotency and proper error surfacing.

  • Testing, CI/CD & observability

    Automated tests, preview deploys, error tracking and uptime alerting configured before you go live.

How it runs

The engagement, step by step

  1. 01

    Scope

    A two-week paid discovery producing flows, a data model, a technical plan and a fixed-price build proposal.

  2. 02

    Foundation

    Repo, CI, environments, auth and the core data layer. The unglamorous sprint that makes the rest fast.

  3. 03

    Build in slices

    Vertical feature slices demoed every two weeks so you see working software, not status decks.

  4. 04

    Harden

    Load testing, security review, error handling, edge cases and accessibility before launch.

  5. 05

    Launch & transition

    Deploy, monitor, document and either hand over to your team or stay on a support retainer.

Client result

What this looked like in practice

“They shipped our customer portal in eleven weeks with tests, docs and a handover session our engineers did not roll their eyes at. Six months later we have added three features ourselves without calling them. That is what a good handover looks like.”

Questions

Web Apps FAQ

Is application work fixed price or time and materials?
Fixed price per phase, quoted after a paid discovery sprint. Discovery is what makes a fixed price honest. Ongoing iteration after launch is usually a monthly capacity retainer.
What happens after the application launches?
You choose. We can hand over to your engineers with documentation, tests and a walkthrough, or stay on a support retainer covering maintenance, monitoring and new feature work.
Can you work in our existing stack?
Usually. We default to Next.js, Node and Postgres or MongoDB, but we regularly work in existing Rails, Laravel and Django codebases. If the stack is one we cannot support well, we will tell you rather than learning it on your budget.
Free, no obligation

Outgrown your spreadsheets and no-code stack?

Walk us through the process that is breaking. We will tell you whether it needs custom software or a better configuration of what you already own.
