The record

Some of these carry a name and some do not. Agency clients are anonymised by vertical and platform, and a public-sector engagement is not described at all - which is exactly the discretion your account would get.

  1. Jungheinrich

    Took over from a full external tech team and now handle all of it: frontend, backend, security, DevOps, updates, consulting, PrestaShop 9.

    One partner in place of a full tech team

    “He took over technical management of 22 Jungheinrich online shops, which were poorly managed by the previous service providers. With very little documentation on a custom set up, he has been able to provide secure and stable environments - and importantly delivering sales growth.”
    Cale Edwards, Senior Research Consultant, Prediki
