Web apps built to be maintained
Web Application Development Company
A web app is not a website with a login. It is a product your team will run for years, extend under pressure and hand to somebody who did not build it. Quanrio builds custom web applications — internal tools, customer portals, SaaS products and platforms — with the architecture, tests and documentation that make year three as productive as month one.

The Second Year Is Where Web Apps Are Won Or Lost
Almost any team can ship a first version. What separates a good build from an expensive one is what happens when the fifth developer joins, the requirements change, and nobody remembers why a module works the way it does. That is decided by boring things: clear boundaries, typed interfaces, tests around the logic that matters, and a deployment anyone on the team can run.
We build that way from the first commit — not because it is purist, but because the alternative is a rewrite eighteen months in, which you pay for twice.
What We Deliver
What We Build
From a single internal tool to a multi-tenant platform, with the pieces that keep it running.
SaaS Platforms
Multi-tenant products with organisations, roles, billing, usage limits and onboarding — modelled properly at the start, since tenancy is the hardest thing to retrofit.
Customer Portals
Self-service for accounts, orders, documents and support, integrated with the systems of record so the portal reduces work rather than duplicating it.
Internal Tools
Operations consoles, admin panels and workflow tools built for speed and keyboard use, because the people using them do so all day.
APIs And Integrations
REST and GraphQL APIs, webhooks, queues and third-party integrations, versioned so your consumers are not broken by your next release.
Data And Reporting
Dashboards, exports and scheduled reports built on a query layer that does not fall over as the tables grow past a million rows.
Infrastructure And Delivery
Scripted environments, CI that runs the tests, staged deploys, monitoring and alerting — so releasing is routine rather than an event.
How We Build Web Applications
Three commitments that shape every web project we take on.
A Stack Chosen For You
We work in TypeScript, React and Next.js, with Node or Python behind it and Postgres underneath by default — but the right answer depends on your team. If you will maintain this yourselves, we pick what your developers already know rather than what we enjoy.
Tests Where They Pay
We do not chase a coverage percentage. We test the logic that would cost you money if it broke — pricing, permissions, money movement, state machines — and add end-to-end cover for the handful of journeys that must never fail.
Handover Is Part Of The Build
Documentation written as we go, a README that gets a new developer running locally in under an hour, scripted environments and no undocumented manual steps. You should be able to change vendors without a rescue project.
How We Run The Build
Step # 1
Discovery And Planning
We start by understanding the problem rather than the feature list: who the users are, what they are trying to finish, and what the business needs out of it.
That turns into a scoped plan — the functionality, the technical requirements, the milestones, the budget and the timeline — before anyone opens an editor.
Step # 2
UI/UX Design
Wireframes first, so the structure is agreed while it is still cheap to change, then the visual design built on your brand.
We prototype the journeys that matter and put them in front of people early, so the interface is tested rather than assumed.
Step # 3
Development
Development runs in short increments you can see. Frontend and backend are built together against a shared contract, so integration is not left as a surprise at the end.
Code is reviewed, environments are scripted, and every increment ships to a staging build you can open yourself.
Step # 4
Quality Assurance
QA runs throughout the build, not as a phase bolted on before launch — functional testing, cross-device and cross-browser checks, performance, and security review.
Bugs are fixed against the increment that introduced them, so the release does not inherit a backlog.
Step # 5
Launch And Support
We handle the deployment, the store or server configuration, and the monitoring that tells us how the release is behaving in the real world.
After launch we stay on it: fixes, improvements, and keeping the stack current so it does not quietly rot.
