    Services

    Our services

    We go deep in three areas: web systems, mobile apps and custom business software. What they share is careful design and maintainable delivery.

    Web development

    We build business web applications and portals that are fast, clear and extendable over time. Our stack is React, Next.js and TypeScript — SSR/SSG where SEO or first load matters, SPA where application UX comes first.

    • Performance- and SEO-aware architecture with measurable Core Web Vitals goals
    • Accessible, responsive interfaces for desktop and mobile use
    • Admin / CMS surfaces or headless content management as needed
    • Operational handover: logging, error tracking and release process

    Mobile applications

    We build cross-platform mobile apps with React Native or Flutter — native-feeling UI, reliable offline behaviour, and workflows people will actually use in the field.

    • iOS and Android from one codebase, with platform-specific polish
    • Push notifications, biometric login and offline-first data handling
    • Backend integration (REST / GraphQL) and real-time sync
    • Automated build and store release pipeline (CI/CD)

    Custom software

    When off-the-shelf software is not flexible enough, we build systems around your processes: ERP integrations, internal portals, dispatch tools, B2B ordering — software that fits how you already work.

    • Domain modelling and API design aligned to business workflows
    • Reliable data layer, access control and auditable operations
    • Integration with existing ERP / back-office systems
    • Security by design: authentication, encryption and roles

    How we work on your project

    1. Agree the task together

      We start with users, existing systems and the intended outcome. These shape the development plan.

    2. Keep progress visible

      Regular demos and agreed decision points make progress clear. Code review, testing and documentation are part of the work.

    3. Plan the handover

      We cover the information needed to operate the system at handover. Support and further development are agreed separately.

    Ways to work together

    How we can work together

    Choose what fits your goal — from a fixed-deadline project to continuous growth.

    Fixed price

    A project with a deadline

    A defined scope, an agreed quote and a predictable schedule. Ideal when you know exactly what you want built.

    Retainer

    Monthly maintenance & development

    Within a fixed monthly budget we develop, monitor and fix. Your system stays current and reliable.

    Partnership

    Long-term development partner

    Aligned to your goals we plan, prioritise and deliver in iterations — a product that keeps improving together.

    What happens in the first conversation?

    We discuss the task, your current tools and important deadlines. Together we establish the next step and what discovery is needed for a grounded proposal.

    A short description of the problem is enough to start. Cost and timing depend on the scope and required integrations.
