Custom software engineering

We design, build and operate software for companies whose systems carry real business logic, real data and real users — and that need a partner who stays responsible long after launch.

We take on projects where engineering quality, long-term reliability and business value matter more than the lowest initial quote.

What we do

Five areas, all of which we practise every day on our own products as well as for clients.

Custom software development

Applications and information systems designed around how your company actually works, not around a template. We start from processes, data and the people who will use the system, and build software that fits them.

Enterprise applications

Operational and business systems with complex logic, large amounts of data and many user roles — the kind of internal systems a company runs its daily work on. We have built and operated such systems for major real estate companies for more than a decade.

System architecture & integration

Architecture design, APIs and integrations that connect applications, data sources and external services. Our own real estate tools exchange data every day: listings entered in a CRM are exported to up to 24 portals and to agency websites.

Modernization & long-term development

Taking over existing systems, stabilizing them, and developing and modernizing them step by step — so that the business keeps running while the system improves.

Infrastructure & operations

Deployment, monitoring and long-term operation of production environments. We run production for our own products, and we build a monitoring product, Moniqo, out of that experience.

How a project runs

The order matters: each step builds on the previous one.

  1. Understand

    Processes, data, users and constraints. We agree on what the system must do and what success looks like.

  2. Design

    Architecture, data model and integrations decided deliberately and written down, with clear trade-offs and a realistic estimate.

  3. Build

    Delivery in steps that can be seen and tested, with performance, security and monitoring built in from the start.

  4. Operate and develop

    Deployment, monitoring and continued development. For us, a system’s life after launch is the normal case, not an extra.

Where we are a good fit

  • Internal business systems that a company runs its operations on
  • Platforms with complex domain logic, data and user roles
  • Integrations between existing systems and external services
  • Existing systems that need a reliable long-term owner
  • Projects where the budget reflects the importance of the system

Where we are not

  • Low-budget brochure websites
  • One-off campaign microsites
  • Projects decided purely by the lowest initial quote

Typical stack in current projects: PHP · Symfony · relational databases · REST API · Linux · containers

Technology follows the problem. We choose tools the client can operate and maintain for years.

Long-term responsibility, in practice

Systems we have built and run for clients — and products we operate ourselves.
