Our products and libraries

What we have built for ourselves — and what we use in client projects.

Three systems we run, and two developer tools that end up in our clients’ code. We maintain them ourselves. Where something similar is needed on your side, tell us about it and we will say what can be reused off the shelf and what has to be built.

Products

Three systems we run

OPK.care

senior care platform

It matches families in the DACH countries with care facilities in Poland. A database of available places, search by care criteria and location, enquiry handling in two languages. We run it as our own product, not as a commissioned project.

Warehouse system with a shop

WMS and e-commerce

Stock levels and warehouse locations managed together with an online shop in a single system, with no synchronisation between two separate tools. In production use at a client.

Translation manager

internal tool

Management of interface texts in multilingual applications: one place for all language versions, control over missing translations, export to the formats used by front-end frameworks.

Libraries

Two tools we use in client code

They came out of problems that kept returning in one project after another. Solved once, then used wherever the problem appears.

TypeScript generator

consistency between front end and back end
ProblemThe types on the front end and the API contract on the back end drift apart after every change, and the fault only surfaces in production.
SolutionTypeScript types generated automatically from the back-end definitions. Drift is no longer possible, because there are no two independent sources of truth — the compiler catches the mismatch before the code reaches the repository.

JSON scopes

control over the data scope in an API
ProblemOne API has to return a different scope of data to different consumers. That usually ends in several near-identical endpoints, or sending everything and filtering on the client side.
SolutionDeclarative field scopes on a single endpoint. Less code to maintain and less data in the response — including data the consumer should not see.

The same team and the same way of working stand behind the packages: AI code audit and security, turnkey software modules, refactoring and technical debt.
