About us

Technology that fits your needs, not the other way round

Our core business is building custom IT solutions – portals based on Liferay Portal and bespoke systems built in Java. Since 2000 we have been developing and deploying systems for private-sector companies and public institutions, and we also take over the maintenance and audit of existing solutions.

We deliver projects end to end – from specification and requirements analysis through deployment at the client’s site to ongoing maintenance. In large projects we work as a dedicated team, selecting the right subcontractors. We often work in an agile model, launching projects in stages and listening to our clients’ requirements.

We advise on the choice of technology, but we do not impose our own views. We want our clients to understand the consequences of their choices – technology should serve their goals, not generate extra costs.

  • 01

    Client needs come first

    We start by understanding processes and data, and only then choose the tools.

  • 02

    Quality on time and on budget

    We follow proven standards and design patterns.

  • 03

    New but proven technologies

    Solutions that meet today’s requirements and leave room to grow tomorrow.

  • 04

    Long-term partnership

    Clients come back to us with new projects – the best measure of our work.

Tools we trust

If we do not yet have expertise in your area of interest, we are happy to gain it.

We choose technology to fit the goals of the project, not the other way round. We work with Java and Spring, Liferay Portal, databases, infrastructure and DevOps, and REST and SOAP integrations, among others.

Our full technology stack – languages and platforms, portals, databases, infrastructure, integrations and the area of analysis and design – is described on a separate page.
