About the studio

ZoTech Studio is an independent software and design studio.

New projects start with requirements and design. For an existing product, we review the code and workflows before agreeing on changes. Every project is led directly by Zo, who runs the studio, so you work with the same person from the first conversation to handover.

  3. 03

    Design & develop

  4. 04

    Test & hand over
