It has been a real pleasure partnering with G Web Pro to build our company website. Our requirements entailed a lot of detail, but G Web Pro was able to accomplish what we needed. Communication and support over the past four years has been great and very responsive. Definitely think of this company for your online requirements.Update:. January 2018:. I'd like to provide an update to my review. Even though our company had to change web providers I am very appreciative and thankful that G Web Pro has assisted us a few times. You guys have incredible knowledge and expertise in this field that can't be found with many other providers. Thanks again Jas for all your help, I'm working on bringing our business back to your company. (BTW, we are a large multinational company).

Web Design Review from Tom Sieron
We launched a new company, designed the branding and website, and needed a WordPress vendor to code it and support it in its growth. I have been running software development companies for the last 15 years, and can fully recommend Space-O Technologies team as a great PM, from a position of his client. They delivered well before time (and we were in a crunch already), and well in budget, while keeping top quality.

I have read previous reviews about the company's interview process and feedback on Google, and they are accurate. A few months ago, I successfully completed all three rounds of interviews, but ultimately, I was not selected for the position. While I accept this outcome, I found the feedback provided to be unprofessional. This reflects poorly on the company's professionalism in selecting employees.Please don't say that I was never applied for the Job in your company.
