Raaz is the backbone of our digital infrastructure. His ability to design and execute large systems with precision is unmatched.
Raaz is by far one of the best programmers I have met not only because he is extremely knowledgeable and talented but also because he is genuinely a really nice guy. He knows how to take care of his clients which is why I have continued to work with him over the past 2 years.
Absolutely amazing job. Very excited we hired the right guy. Raaz did an incredible website for us. He was easy to get a hold of and was very patient with our site 'tweaks.' He took the time to explain what he did to the site and where I can see it on the back end.
Raaz is a very experienced coder that knows what he's doing. He did this project in a matter of hours, compared to other freelancers who could simply not deliver. I highly recommend him to anyone looking for a qualified programmer.
Raaz is an absolute pleasure to work with. He is a highly skilled and talented web designer. He was very patient with me and the many revisions I kept asking him to do...he would not stop until I was 100% satisfied. I would highly recommend him to anyone looking for a true expert.
From onboarding systems to technical documentation, Raaz handles it all with great detail and dedication.
