Web application development for the systems behind your site
Backend systems, APIs and databases built and connected to your site by the same hands — not a front end handed off to a separate development team.
When a site needs to do more than display pages
A marketing site shows information. A business often needs something that does more: a booking system with its own logic, a customer portal, an internal tool that replaces a spreadsheet three people edit at once, or an API another system can call. That's a different kind of build — one a front-end-only site was never meant to carry.
Bolting a database and some server logic onto a site built for neither rarely holds up. A web application built around what the business actually needs to track, store and process is a different starting point entirely — and it's the one that scales past the first six months.
What's included
Backend built for the job
Spring Boot services in Java or Kotlin, sized to what the application actually needs — not a generic framework installation left mostly unused.
APIs and database design
REST APIs and a database schema planned around the business's real data, not a table structure copied from a tutorial.
Connected to the front end you already have — or a new one
A web application built to work with your existing site, or as part of a new one, built by the same hands so nothing gets lost between the two.
Built to be maintained
Code that whoever supports it later can actually read — no undocumented shortcuts that only make sense to the person who wrote them at midnight.
How it's built
The same person who designs the front end builds the backend behind it — one line of communication, from the first conversation about what the system needs to do, through to launch.
Every application starts from what the business actually needs to track or automate, not from a template project. The result is a system sized to the real workload, not over-built for traffic that doesn't exist or under-built for the data that does.
A live system built this way
RallyTara's live results run on exactly this kind of connection: results pulled directly from the organizers' own Google Sheets, with no manual re-entry, alongside a self-serve news section they update themselves through an admin panel — a small application layer, built and hosted by the same person who built the site around it.
Questions worth asking before you start
What counts as a 'web application' rather than just a website?
A website mostly displays information. A web application does something with data — it stores it, processes it, lets people log in and see something specific to them, or talks to another system. If your site needs to remember something between visits or make a decision based on data, that's application territory.
Do you build the backend even if someone else built the front end?
It's usually more reliable when the same team builds both, since a backend and its front end share a lot of assumptions about how data flows between them. Connecting to an existing front end is possible and depends on what's already there — worth a conversation before assuming either way.
What does a custom web application cost?
It depends on what the application actually needs to do — a simple internal tool and a customer-facing system with its own logic are very different projects. You'll get a written quote after a short conversation about scope, not a number up front.
What technology do you build with?
Spring Boot (Java or Kotlin) on the backend, with the database and API design fitted to what the application needs — paired with an Angular or hand-built front end, depending on the project.
Can you connect a new application to systems we already use?
Often, yes — see the integrations and automation page for what that usually involves.
