We use AI tools to support our work, primarily Claude Code. We use it for specification, programming, testing and code review. For each project we prepare a context with an architectural description and rules, so Claude follows our standards. Decisions and responsibility for the code remain with the developer.

- Build websites and portals on Umbraco CMS.
- Collaborate on specification and solution design.
- Use Claude Code to prepare specifications, code and tests, and review them critically.
- Participate in code reviews.
- Work with the team and clients to take projects from idea to production.
