What we build

Complex applications,
delivered properly

Web applications are fundamentally different from websites. They need to handle authentication, databases, real-time data, payments and complex user flows. We have built all of these and we know where the pitfalls are.

🔐

Authentication and user management

Secure login flows, role-based access control, social OAuth, email verification and multi-factor authentication. Built properly from day one.

🗄️

Database architecture

Relational database design with Supabase and PostgreSQL. Row-level security, real-time subscriptions and optimised queries that scale with your users.

💳

Payments and subscriptions

Stripe integration for one-time payments, recurring subscriptions, usage-based billing, customer portals and webhook handling.

📊

Dashboards and analytics

Data-rich dashboards with charts, tables, filters and exports. Built to display the metrics your users actually care about, fast.

🔔

Notifications and email

Transactional emails, in-app notifications, webhooks and real-time updates. Keeping users informed at every step of their journey.

🌐

API integrations

Connect your app to third-party services: CRMs, payment processors, communication tools, data providers and more.

Our process

How we deliver
complex applications

01

Technical discovery

We map out your application requirements, user flows, data models and integrations. We identify technical risks early and propose the right architecture before writing a single line of code.

02

Design and prototyping

Interactive Figma prototypes for key user flows. We validate the UX before building so we catch issues early when they are cheap to fix.

03

Development in sprints

We build in two-week sprints with regular demos. You always know what has been built, what is coming next and where the project stands against the timeline.

04

Testing and QA

Unit tests, integration tests and manual QA across browsers and devices. We test edge cases, error states and security before every release.

05

Launch and monitoring

We deploy with CI/CD pipelines, set up error monitoring and performance tracking, and stay available for the post-launch period to handle anything unexpected.

Technology

FAQ

Questions about
web applications

How much does a web application cost?+
Web applications start from €5,000 for simpler projects and can range to €20,000 or more for complex platforms. The price depends on the number of features, integrations and complexity of the data model. We always provide a fixed-price quote after a discovery call.
How long does it take to build a web app?+
A straightforward web application typically takes 4 to 6 weeks. More complex platforms with multiple user roles, integrations and custom business logic can take 8 to 12 weeks. We provide a detailed timeline in your proposal.
Can you build a SaaS product from scratch?+
Yes. Building SaaS platforms is one of our specialisms. We handle everything from authentication and multi-tenancy to subscription billing with Stripe, onboarding flows and admin dashboards. We have done it before and we know what to watch out for.
Who owns the code when the project is done?+
You do. We hand over the full source code with documentation at the end of every project. We also provide a handover session to walk your team through the codebase and deployment process.
Can you take over an existing project?+
Yes, we can. We have experience picking up existing codebases, assessing the technical debt and either improving or rebuilding where necessary. We will be honest with you about what we find and what we recommend.
