Testimonials
-
Kévin carried out a complete audit of Docstring's compliance, covering both the legal documentation and cybersecurity. The audit was very precise and thorough, and Kévin was able to work almost autonomously thanks to his skills on both the legal and the technical side. Very satisfied, then, with the overall work he delivered 🙂
Docstring Translated from French -
I highly recommend Kévin. We were pleasantly surprised by his management and organisational skills. He carried out his work efficiently, with clear communication and flexibility.
Founder of Hyping (Minecraft server) Translated from French -
Kévin was exceptional and understood my needs perfectly. He supported me very effectively in my project, with remarkable speed. I highly recommend him, 100%!
