“Quality of delivered work is outstanding”
Our company worked more than 5 years in total with NIX. Communication was always very clear and direct. Being a remote company, wasting time in communication is horrible, luckily with NIX, we experienced no delay or misunderstanding.
Quality of delivered work is outstanding, all tasks prior to delivery were tested in detail, and bugs or mistakes were virtually non-existent.

“It is hard to impress me, and NIX kept me happy”
There is no recommendation that is more powerful. NIX’s expert team built a new system that increased potential customer traffic and improved performance.

“Delivering high-quality code”
With NIX, I have broken some of my own rules of team composition with respect to the ratio of FTE and 3rd party engineers. I have some teams that are more than 50% NIX because the code coverage, quality, and velocity coming out from the NIX developers are very good. Delivering high quality code in a predictable manner has built trust and confidence with my management/full-time employees.

“You have done the work perfectly”
I want to say thank you for the excellent, highly professional work, for your passion, and your time even on holidays and weekends. Your attitude ultimately led to outstanding results. We are satisfied with the result we’ve achieved, but we need to keep working, and actively use every opportunity to make it better. You have done the work perfectly and the application, which you created in such a short time, turned out to be very functional and cool.

“CMS team are my go-to partners for web dev”
I’ve been working with these guys for years now – particularly their CMS team. The relationship has been very positive, and they continue to do great work for me.
I first hired NIX around 2008 to re-build a website that was built (poorly) by another agency. NIX solved that problem and has helped me build and launch multiple products since then. Roman and his CMS team are my go-to partners for web dev.
Consultant & Advisor at DemandSide
“Quickly and professionally”
I have used NIX for 3 different companies over the past 3 years that I have been CTO of. Projects have spanned a wide variety of technology stacks.

They quickly and professionally get up to speed with our current processes and seamlessly merge with any professional environment.
