What clients say
Keith was extremely fast to respond (faster than any other tech on AWS) and was able to instantly do a screen share with me, diagnose and troubleshoot the issue and get me back up and running within less than 45 minutes. Highly recommend.
Absolutely amazing with vast knowledge on end-to-end infrastructure setup. Very precise and clear based on your requirements — and genuinely here to help. Most importantly, no greed for overcharge. Highly recommended.
A natural cloud expert who can dig into the problem and find the different solutions. It is a pleasure to work with StackRef!
We also offer our own designed, self-hosted, soup-to-nuts, internal hackathon manager.
