Very happy with Christopher's service. He is someone who is involved, who has shown a lot of availability and efficiency.
I called on him for an MVP with a specific feature of connecting members and private messaging, and the result far exceeds my expectations. We had excellent communication, Christopher is responsive, he was able to listen to my needs and advise me when necessary.
In terms of efficiency and time I couldn't have fallen better, the site was done in 1 week with an unbeatable quality/price ratio! Everything was great! I recommend Christopher to 200%, and will call on him again without hesitation to develop the new features of the site ;-)

Very good experience with Christopher!
I was looking for a very short mission and had small expectations. Christopher went far beyond what I expected (and what I asked for)
Communication was good and the price unbeatable
=> Cost / quality / deadlines: Here, everything is top notch
I highly recommend!
...take advantage of it quickly before Christopher increases his DJM ;)
