What we build.

  1. 01

    AI integration and agents

    Processes · Automation

    We integrate AI into internal processes where the work is repetitive and the result can be measured: document processing, classification and data extraction, agents and automations that work directly inside the systems you already run. Model access goes through a single gateway with cost limits, logging and clear rules about which data reaches which model.

  2. 02

    MCP servers

    AI assistants · Integration

    We connect your systems to AI assistants through the Model Context Protocol: documented MCP servers with clear permissions and an audit log, so the assistants your team or your customers use read data and take actions only within the limits you set.

  3. 03

    AI compliance

    AI Act · Documentation

    We bring AI systems up to the transparency requirements of the European Artificial Intelligence Act: users are told they are interacting with an AI system, generated content is marked, and actions stay in an audit log. The transparency obligations have applied since August 2, 2026. We deliver the implementation in code and the technical documentation of the system.

  4. 04

    Web applications

    React · SSR

    Platforms and browser applications rendered on the server, designed to load fast the first time and to stay easy to maintain at the hundredth release.

  5. 05

    Online stores

    Shopify · Custom

    We build online stores on Shopify or from scratch: product catalog, payments, shipping and invoicing in one system, with pages that load fast on phones as well.
