React & React Native App UI/UX & Development


Collaborative Design and Development Gets System Design Right the First Time

“Cloud City’s help getting our apps off the ground gave us breathing room to build a kick-ass team and product, which eventually led to us being acquired.”

"Having many IoT devices pinging not only each other, but also sending data securely to service managers, technicians and homeowners is quite a challenge.

Building fully integrated systems like these that will not only work reliably and securely, but can also scale to very large numbers of installations is also not trivial by any means

When faced with engineering and design problems of this nature, with ever-changing screen dimensions, sensitive homeowner data, and heavy service manager loads, it is most reassuring to have a team with programming and design pattern expertise working right along with you.

Cloud City's staff is highly professional, experienced, cooperative, works hard, and delivers high quality output. They are also a lot of fun to work with. We just went through a third-party security audit for due diligence with them, which entailed a lot of detailed analysis. Thankfully, Cloud City had anticipated just about all of the issues that would have otherwise caused us a lot of remedial work."

And which caching technique you choose depends on your use case as the optimum caching for a repeated-use application is at odds with the optimimum technique for marketing sites.
