Roger Chi Consulting Reviews
Roger did a great job. He delivered the project quickly, addressed any issues and provided solid documentation.
Excellent knowledge, attitude and timeliness.
I run a small company that periodically needs some serious help with technology issues that come up. We are generally looking for someone who can very quickly grasp the problem and create a solution without having 10 meetings just to assess the scope of the problem. Roger filled that bill exactly. He worked with me personally and was able to efficiently help identify the changes we needed to make to address a critical problem with our efforts to bring together an FSx instance with our APPSTREAM infrastructure so everything was integrated into our Active Directory in a way that significantly reduced our security vulnerabilities. The issue was relatively small - Roger did not try to extend the problem and provided the right advice to allow us to move forward. I will reach out to Roger the next time we need assistance.
Roger really helped me to choose a better cloud development path than I had planned, leveraging more powerful services, appropriate to our scale, at a clear cost advantage. Exactly what you would expect from a true AWS Expert! Will certainly be working with him again.
Roger was very responsive and delivered exactly what I was looking for. I would work with him again.
Communicates exceptionally well, provides timely work, and does what he says he will do
