Web Application Development

Web apps that look good, run fast, and your users will actually enjoy.

You get web applications built start to finish: polished interfaces, load times under a second, and security worked into every layer. One team owns the whole thing, so nothing falls through the cracks between specialists.

  • Design driven by usability, not just how it looks
  • A Lighthouse score of 95+ on every build, not only the demo
  • OWASP Top 10 closed before go-live, with a pen test included
  • One team owns the full stack, start to finish

What we deliver

Four capabilities, one engineering team.

Design, performance, security, and full-stack engineering are all handled by the same team within the same build. There are no agency handoffs and nobody to point fingers at when something goes wrong.

Design

Interfaces people actually trust

Your interface is shaped around how people really use software, which is rarely how a developer would assume. Usability comes first. Looking good comes a close second.

  • Wireframes and high-fidelity screens with three rounds of revisions
  • Layouts shaped by how real users move through the product
  • A consistent visual language that holds up in every state
  • Tested on phones and tablets, not just desktop

Performance

Lighthouse 95+ on every build

A slow page loses you people before they read a word. Speed is built in from the first commit, so it's part of your foundation rather than a checklist scrambled through before launch.

  • Code splitting, lazy loading, and tree-shaking set up by default
  • Image optimisation and CDN delivery from day one
  • Time to First Byte under 200ms across every environment
  • Render-blocking scripts cleared out before anything ships
See the details
Security

Hardened against the OWASP Top 10

Security is part of how your app is built, not something added once it's already live. The vulnerabilities that attackers genuinely go after are closed before your app reaches production.

  • The OWASP Top 10 handled in both design and code
  • Secrets kept in environment vaults and never committed
  • Dependency vulnerability scans run in CI on every pull request
  • A penetration test before every go-live
See the details
Engineering

One team across the whole stack

Frontend, backend, APIs, and database are all owned by one team. That means no awkward handoffs and no boundary bugs that nobody wants to claim.

  • React frontends in TypeScript, tested end to end
  • Node or Python backends with clean, well-defined APIs
  • PostgreSQL, Redis, and the data layer set up properly
  • AI and LLM features built as part of the core deliverable

Core values

Three things we won't trade away to ship faster.

When a deadline gets tight, plenty of agencies quietly cut design, performance, or security. We hold all three to the same standard on every project, no matter the timeline.

Design

Design people come back to

Design is often what decides whether someone trusts your product or gives up on it after one frustrating session. It starts with wireframes that map how people actually move through the product, builds those out into high-fidelity screens, and keeps refining until each interaction feels obvious.

  • Your user journey is mapped before a single screen is drawn
  • Every screen goes through three full rounds of revisions
  • Accessibility is part of the design from the start
  • Figma handoffs are detailed enough for developers to build from directly
Performance

Speed is a product decision

Even a one-second delay in load time costs you conversions. So speed is treated as a real engineering concern from the first commit, rather than something to fix in a sprint after launch. A Lighthouse score of 95+ is your starting line.

  • A Lighthouse score of 95 or higher on every deployment
  • Core Web Vitals watched in production, not just in testing
  • CDN and edge caching set up before go-live
  • Performance budgets enforced automatically in CI
Security

Checked before it ships

Most breaches come down to preventable mistakes: SQL injection, cross-site scripting, broken authentication, secrets left in the wrong place. The OWASP Top 10 covers the worst of them. Every one is closed on your project, with a penetration test before go-live.

  • A full OWASP Top 10 review on every project
  • Automated security scanning built into the CI pipeline
  • A penetration test before launch
  • Secrets handling, HTTPS, and rate limiting on by default
How we work

Five steps, and everything is yours at the end.

At launch you get the full source code, the documentation, and a working CI/CD pipeline. You won't be tied to us just to keep the project running.

01

Discover

Your users, your business logic, and the constraints you're working within come first, not just the feature list. You sign off on the scope in writing before any code is written.

02

Design

Wireframes first, then high-fidelity screens, with three rounds of revisions along the way. The Figma files are ready for developers to build from.

03

Build

Frontend, backend, and security all move forward together. Automated tests run on every pull request, and nothing reaches staging until it passes them.

04

QA

We test across browsers and devices, run a penetration test on the full application, and confirm the Lighthouse score is 95 or above.

05

Launch

We set up CI/CD, monitoring, and alerting, then hand over the full source code, documentation, and a walkthrough session. Everything is yours from the start.

FAQ

Questions clients ask before working with us.

How long does a typical web application take to build?

A well-scoped MVP usually takes 8 to 14 weeks from discovery to launch, depending on how many features and integrations are involved. We always begin with a scoping session, so you have a realistic timeline before you sign anything.

Do you handle design and development, or just one?

Both, from start to finish. Design and engineering are the same team here, so there's no handoff between two separate agencies. The design stays grounded in what can actually be built, and the engineering stays grounded in what users need.

What does 'security by default' mean in practice?

It means the OWASP Top 10 is considered at design time, secrets live in environment vaults from day one, and dependency scans run in CI on every pull request. A penetration test before each go-live is included rather than sold as an optional extra.

Can you add AI features to an existing web app?

Yes. We build LLM-powered features such as search, document processing, conversational interfaces, and workflow automation, and we hold them to the same performance and security standards as the rest of the app. That works for new builds and for apps you already have running.

Why React, Node, and PostgreSQL? Can I pick a different stack?

We default to React, TypeScript, Node or Python, and PostgreSQL because they are mature, widely supported, and easy to hire for, which protects you long after launch. The choice is always driven by your needs, so if your team already runs a different stack or has a specific constraint, we adapt rather than force a rewrite. We will explain the trade-offs in plain language before anything is locked in.

Who owns the code, and how does handover work?

You own everything outright: the full source code, the design files, and the documentation are yours from day one, with no licensing strings attached. At launch we hand over the repository, a working CI/CD pipeline, and a walkthrough session so your team can run and extend the app on its own. You are never locked into us just to keep the product alive.

Do you offer ongoing maintenance and support after launch?

Yes, and it is optional rather than mandatory. We offer monthly support plans covering bug fixes, dependency and security updates, monitoring, and small feature work, sized to how active your product is. If you would rather your own team takes it over, the handover is built so they can, and you can still call us for occasional help.

Will the app handle growth in users and traffic?

Scalability is designed in from the start: stateless services, sensible database indexing, caching with Redis, and a CDN in front of static assets. We load-test against your expected traffic before launch and set up monitoring so you see bottlenecks early. When you need to scale further, the architecture supports horizontal scaling without a rebuild.

Can you integrate with third-party services we already use?

Yes. We regularly integrate payment gateways, CRMs, email and messaging platforms, analytics, and internal APIs, and we handle authentication, error states, and rate limits properly so the connection stays reliable. If a service has no clean API, we will tell you upfront and propose the most stable workaround. Each integration is documented so your team knows exactly how it is wired.

What happens if we need changes or new features after launch?

Post-launch changes are normal, and the codebase is built to make them straightforward: clean APIs, tests, and documentation mean new work does not break what already ships. You can bring changes to us, or your own developers can pick them up directly from the handover. We can also work in short iterations after launch if you want a steady stream of improvements.

Where is the app hosted, and how is it deployed?

We deploy to your choice of Google Cloud, AWS, or a similar provider, set up under your own account so you keep full control and billing visibility. Deployments run through an automated CI/CD pipeline with staging and production environments, so releases are repeatable and easy to roll back. We hand over the infrastructure setup and documentation so nothing depends on us to operate.
