Communication with him was good in general, but the creation of a simple sharepoint intranet page based on a pre-provided template didn't meet our quality expectations at all. Needed a lot of guidance and inputs, finally still paid the agreed amount for without dispute case as we ran out of patience.

Exceptional service and knowledge. I would never have been able to do this on my own. I would still be staring at the blue screen of death.

It was a pleasure working together. He understood my direction right away and translated it into a clean, polished, and elevated pitch deck. Very easy to communicate with and quick with updates. I’m very happy with the final result!
