Web Applications

The gap between a website and a web application is state. Once users have accounts, data that changes, permissions that differ and actions with consequences, you are building software that happens to run in a browser — and it needs the engineering discipline that implies, not the timeline of a marketing site.

What this covers

Browser-based applications that handle real users, real data and real concurrency without degrading.

• Application architecture and data modelling
• Authentication, roles and access control
• Complex interface and interaction design
• Real-time features and collaborative editing
• Offline capability and progressive web apps
• Performance optimisation at scale
• Testing, monitoring and observability

Where web applications usually go wrong

Data model designed last. Interface-first development produces schemas that fight every later feature. The model deserves the first serious design conversation, not the final one.

Performance treated as a launch task. Query patterns and payload sizes are architectural decisions. Discovering that at load-testing time means rework, not tuning.

State management by accretion. Applications that grow without a deliberate state strategy reach a point where every change breaks something unrelated.

No error boundaries. Software that fails silently or fails entirely, rather than failing in a contained and legible way, is far more expensive to support.

How we build it

1. Architecture and data design. Entities, relationships and access patterns settled before feature work starts.
2. Interface design. The core workflows designed properly, including the empty, loading and error states that determine how the product actually feels.
3. Incremental delivery. Features shipped to a staging environment continuously, with automated tests covering the paths that matter.
4. Launch and observe. Monitoring and error tracking live from day one, so you learn about problems before your users report them.

Technologies we work with

• Frontend: React, Next.js, Vue, TypeScript
• Backend: Node.js, Python, PHP, Go
• Data: PostgreSQL, MongoDB, Redis
• Real-time: WebSockets, server-sent events
• Infrastructure: AWS, GCP, Vercel, Docker, CI/CD

What you get

• A tested application with documented architecture
• Source code and infrastructure you own
• Monitoring and error tracking configured
• Deployment pipeline and environment setup
• Documentation written for whoever maintains it next

Frequently asked questions

How is this different from web development?

Our web development service covers sites and content-driven builds. This covers applications with accounts, permissions and stateful data — closer to software engineering than site building, with the testing and architecture work that comes with it.

Can you take over an existing application?

Yes. We start with a codebase and architecture review so you get an honest assessment of what is there before anyone commits to a plan.

Do you handle hosting and infrastructure?

We set up infrastructure, deployment pipelines and monitoring as part of the build. Hosting runs in your own cloud accounts, so you retain control and there is no dependency on us to keep the lights on.

How do you handle scaling?

By designing for your realistic load and instrumenting properly, so scaling decisions are driven by measurements rather than guesses. Premature distributed architecture causes more outages than it prevents.

How we start

Every engagement starts with a short, fixed-scope conversation. You leave with a plan and a price whether or not you continue with us.
