    (01)What We Build

    Software That Works for You

    From internal tools to client portals, we develop applications that streamline your business processes and make your team more productive.

    • Custom Dashboards

      Clear dashboards for your team with real-time data, KPIs and reports, precisely tailored to your business processes.

    • Workflow Automation

      Convert manual tasks into automated flows. From approval processes to notifications and status updates.

    • Database & Data Management

      Secure, scalable databases that grow with your business. CRUD operations, search functions and data exports included.

    • Roles & Permissions

      User management with role-based access. Admins, managers and employees only see what's relevant to them.

    • Integration with Existing Tools

      Seamlessly connect with your current software, CRM, accounting, email, calendars and more via APIs.

    • Security & Privacy

      Encryption, secure authentication and GDPR compliance. Your business data is in good hands.

    • Iterative Development

      We build in sprints with regular demos. This way you can steer where needed and get exactly what you expect.

    • Technical Maintenance

      After launch, we handle updates, bug fixes, monitoring and further development. Always up-to-date.

    Approach, pricing and outcome

    When custom software is cheaper than off-the-shelf

    Off-the-shelf software is almost always the right answer, right up until you're stitching three packages together with CSV exports, or paying licences for users who need one screen. From that point on, a custom application isn't a luxury but a cost you earn back. We build those applications on a modern stack (React, TypeScript, Supabase) so you or another team can keep developing them later.

    1. 1. Scoping and data model (week 1)

      We describe the user roles, the screens they need and the data model underneath. This is the phase where most of the cost is decided: every role you add later touches authorisation, screens and reporting at once.

    2. 2. Working version in sprints (weeks 2–6)

      Every sprint delivers a version you can actually use, not a screenshot. That way you see early whether the process holds up in practice and can adjust before everything else is built on top of it.

    3. 3. Permissions, logging and security

      Roles and permissions are enforced at the database level (row level security), not just in the interface. Actions are traceable, and sensitive data stays inside the EU infrastructure of your choice.

    4. 4. Delivery and hand-over

      You get the source code, documentation and an admin environment where you manage users, content and settings yourself. Every project includes three months of free support; maintenance after that is optional.

    What we typically build

    Client portals with documents, project status and messaging; internal dashboards that combine data from several systems; booking and request flows; and marketplaces with multiple roles and payments. Our own client portal, including project progress, quotes and messaging, runs on exactly the same stack we deploy for clients.

    A good fit if

    • Your process currently lives in Excel or scattered tools and is error-prone.
    • You pay licences for features you never use.
    • Your clients or staff need their own environment.

    Less suitable if

    • An existing package already covers 90% of your process well.
    • Requirements aren't settled yet, start with a short scoping instead.
