Web application development

Web applications built to grow past the first version

SaaS products, customer portals and internal tools that run in the browser. We ship a focused first version quickly, then keep the architecture clean enough that the tenth feature is as easy to add as the second.

  • A working release every 2 to 3 weeks
  • Security built in from the first sprint
  • Architecture decisions written down

What we build

Web applications for customers, teams and partners

SaaS products

Multi-tenant products with sign-up, onboarding, plans and billing, and the admin tools your support team needs.

Scoping a first version →

Customer portals

Self-service accounts where customers order, track, pay and download without calling your team.

Internal tools

Operations, approvals and back-office tools that replace spreadsheets and shared inboxes.

Marketplaces and booking

Two-sided platforms with listings, search, scheduling, payments and payouts between users.

Dashboards and reporting

Live dashboards over your own data, with exports and scheduled reports for the people who need them.

APIs and integrations

Public and private APIs, webhooks and connections to the systems your application depends on.

Build, buy or no-code?

When a custom web application is worth it

Custom software costs more up front. It pays off when the process is specific to you, when per-seat pricing grows faster than you do, or when the application is the product you sell. Our guide to building or buying software goes deeper.

Architecture

Five layers, each with a clear job

We keep business rules in the API, buy commodity services like sign-in and billing instead of building them, and set up operations before the first feature. Every significant choice is recorded in a short decision note, so the next developer knows why.

What business buyers will ask for

If you sell to companies, their IT and security teams will have a checklist. These are cheaper to build in from the start than to bolt on after the first big deal.

  • Tenant isolation so one customer never sees another
  • Roles and permissions that match how teams work
  • Single sign-on with SAML and OpenID Connect
  • An audit log of who changed what and when
  • Plans, seats and invoices through Stripe
  • Data export and deletion on request
How a project runs

From discovery to a first release

  1. Discovery

    2 to 4 weeks

    Users, roles, integrations and the riskiest feature prototyped. Ends in a scoped estimate.

  2. Foundations

    2 to 3 weeks

    Architecture, environments, sign-in, CI/CD and monitoring in place.

  3. Build

    8 to 16 weeks

    Sprints of two to three weeks, each ending in a demo on staging.

  4. Hardening

    3 to 4 weeks

    Load, security and accessibility testing, plus acceptance testing with real users.

  5. Launch

    Ongoing

    Go live with the team on hand, then iterate on what users do.

Questions

Web application development FAQ

How much does a web application cost to build?

It depends on the number of user roles, screens and integrations. A focused first version of a SaaS product or internal tool is typically a few months of work for a small team. Discovery ends with a scoped estimate and a range, and our guide to development costs helps you compare it with hiring.

How long until we have a first release?

Three to six months to a first release is typical for a mid-sized application with real users, several roles and a handful of integrations. You see working software on staging every two to three weeks before that. This breakdown shows where the time goes.

Which technology stack do you use?

Usually React or Next.js on the front end with Node.js, .NET or Python behind it, and PostgreSQL for data. We choose from what your team can hire for and maintain, and we explain the choice in writing.

How do you handle security?

From the first sprint: authentication through a proven provider, role-based permissions, encrypted data, dependency scanning in the pipeline and the OWASP Top 10 as a checklist. For regulated clients we arrange an independent penetration test before launch.

Will it scale if the product takes off?

We design for the growth you expect, not ten times beyond it, so you do not pay for scale you may never need. The architecture keeps the obvious next steps open, such as read replicas, caching and background workers, and we load test before launch.

Do we own the code?

Yes. The code is in your repository from the first commit, the contract assigns all intellectual property to you, and the infrastructure runs in your own cloud account.
