Web application development
Applications that run in the browser, handle real workloads and hold up when several departments depend on them at once.

Support after launch
A web application is different from a website. Visitors read a website; users work inside an application. That changes almost every technical decision — how state is managed, how permissions are enforced, how the system behaves when two people edit the same record.
We build browser-based applications where the hard parts are the ones nobody sees: the data model, the access control, the audit trail and the API that keeps the front end and the back end honest with each other.
Problems this solves
Desktop software tied to one machine
Legacy applications installed on a single office PC block remote work and become a single point of failure.
Permissions that are too coarse
Systems with one shared login make it impossible to know who changed what, and impossible to limit what junior staff can see.
Slowing down as data grows
Applications built without indexes or pagination work fine on sample data and crawl once there are two years of records.
No reliable audit trail
When a figure changes and nobody can establish who changed it or when, disputes become impossible to resolve.
What the work covers
Data modelling
Schema design, relationships, indexing and migration strategy.
API layer
REST or GraphQL services with versioning, validation and rate limiting.
Front-end application
Component-based interfaces with real state management, not page reloads.
Authentication and roles
Sessions, multi-factor options and permissions granular enough to be useful.
Reporting
Filterable views, exports and scheduled reports that finance will actually accept.
Audit and logging
A record of who changed what and when, retained for as long as you need it.
How the layers fit together
A web application is a stack of responsibilities. Keeping them separate is what makes the system testable, secure and possible to change later without breaking everything above it.
Browser client
Component UI, routing and local state.
API gateway
Request validation, throttling and versioned endpoints.
Authentication
Identity, sessions and role checks on every request.
Business logic
Rules, workflow and calculations in one place.
Data layer
Schema, queries, indexes and transactions.
Infrastructure
Hosting, backups, logging and monitoring.
What you end up with
Accessible from any device with a browser
Role-based access instead of shared logins
Performance that holds as records accumulate
A documented API other systems can integrate with
Complete audit history
Deployed and updated without touching every desktop
Technologies we commonly use for this
The stack is chosen per project — from your requirements, your existing systems and who will maintain it afterwards. This list is what we reach for most often, not a fixed answer.
Ways to work together
Model A
Fixed scope, fixed price
The scope is written down in detail before work starts, and the price is fixed against it. Changes are quoted separately as they come up.
Best for: Well-understood projects — a website, a defined module, a rebuild.
Model B
Monthly retained team
An agreed number of developer days each month, directed by your priorities. Scope can move without renegotiating a contract.
Best for: Products that will keep evolving after the first release.
Model C
Phased delivery
The system is split into phases that each ship something usable. Every phase is quoted before it begins.
Best for: Large ERP, SaaS and platform builds where the full scope is big.
Model D
Support and maintenance
Ongoing care for a system that already exists — ours or someone else’s — covering fixes, updates and small enhancements.
Best for: Live systems that need a reliable pair of hands.
Sectors we apply this in
Frequently asked questions
A website mainly presents information. A web application lets people do work — create records, run processes, make decisions. Applications need authentication, permissions, validation and an audit trail, which is where most of the engineering effort goes.
That is an architecture and hosting question, and we answer it during planning rather than after launch. We size the database, caching and server capacity against your expected concurrency with headroom for growth.
Usually yes. We can build against an existing schema, or run the new system alongside the old one with a synchronisation layer while you transition.
Where it genuinely matters — field teams, patchy connectivity — we build a progressive web app that caches data locally and synchronises when the connection returns.
