Software that does exactly what your business needs

From the first conversation about a problem to a system running in production — we design, build and maintain applications shaped around real processes.

Off-the-shelf tools stop where your company's specifics begin. When a team runs key processes in spreadsheets, stitches work together across three mismatched systems, or postpones decisions because "the system can't do that" — that's usually the moment for software written for the actual problem.

Our development team runs the project from requirements analysis through launch and maintenance — the same accountability at every stage, with no chain of intermediaries between you and the code. You get the scope and estimate in writing before you pay anything, and you see progress in a working product, not in reports. We'll also say so plainly when an off-the-shelf tool solves the problem for less — we write code where it genuinely pays off.

Testing, version control, CI/CD and documentation are not a paid add-on here — they are a condition of the work, carried over from the enterprise projects the firm's engineering practice was built on: environments at PwC, Roche and E.ON. In practice that means one thing — a year from now, somebody else can still open this code and change it safely.

What the service covers

  • Internal systems and process tools

    Your team runs its key processes in one system instead of spreadsheets and email — we build process management systems, admin panels, document routing and workflow tools that off-the-shelf software doesn't cover.

    • Booking and request-handling systems
    • Loyalty systems and CRM-style solutions
    • Admin panels and reporting tools
    • Document routing and approval flows
  • MVP and proof of concept

    You put the product in front of customers or investors quickly: we cut the scope down to what actually validates the idea and build the first version on an architecture ready to grow — not one that needs rewriting from scratch six months later.

  • Modernising and rescuing existing systems

    You get back control of a system your business depends on: we take over applications from previous vendors, refactor the code, upgrade outdated technology, fix defects and bring the project back to a state where it can be developed safely.

    • Audit and takeover of another vendor's code
    • Refactoring and paying down technical debt
    • New feature development in an existing system
    • Ongoing application maintenance
  • System integrations

    No more retyping data between systems by hand: we connect applications that don't talk to each other today — through API integrations, data synchronisation and automated document exchange.

Typical situations

  • A core company process lives in a spreadsheet that "only one person understands".

  • An off-the-shelf system covers 80% of your needs, and the missing 20% costs the team hours of manual work every week.

  • The previous vendor disappeared, and the application your business depends on has no documentation and no one maintaining it.

  • You have a validated product idea and need a first version you can put in front of customers or investors.

What you can count on

  • A system designed around your processes, with the scope and price in writing before you pay anything.
  • Code that is tested, version-controlled and documented — a system any future team can take over.
  • Regular working releases to click through instead of progress reports.
  • One line of accountability for the whole — architecture, code, tests and deployment — instead of three vendors pointing fingers.

Projects in this area

Selected work where this scope was part of the delivery.

  • IZAPzoo

    IZAP, a brick-and-mortar retail chain, wanted its own loyalty programme on customers' phones instead of plastic cards. We designed and built the whole thing — Android and iOS apps, a cloud backend and an admin platform — and store staff now run points, rewards and promotions themselves.

Questions about this service

We answer that with a process rather than a number: a free first conversation and a short analysis, after which you get a concrete quote with the scope written out. Larger projects we split into stages, so a first working version ships early and the budget stays in your hands after every stage.

The rights to the code, the repository and the documentation, and the handover of access, are set by the contract signed before work starts. You can stay with us for ongoing maintenance, keep developing the system in stages, or hand it to your own team — we run the project so that each of those options stays realistic.

Yes — regularly. We start with an audit of the code and infrastructure, after which you know exactly what state the project is in and what needs attention first — only then do you decide on further work. And if the audit shows the system is cheaper to rewrite than to rescue, we say so plainly.

Yes — we run software projects remotely for companies across Poland and abroad, with regular online check-ins. On-site meetings are available in and around Bydgoszcz.

Related services

  • Web applications

    Browser-based systems — operations panels, client portals, dashboards and SaaS products — with permissions, integrations and performance sized for a real load.

  • Mobile apps

    We build Android and iOS apps from one React Native codebase — loyalty, customer-facing and internal — and run them from design through store release to maintenance after launch.

  • QA and software testing

    Manual and automated testing, API, UI and regression tests, plus test strategy — a quality process that actually protects your releases.
