React & React Native App UI/UX & Development


Collaborative Design and Development Gets System Design Right the First Time

Intelligent sensing for HVAC handles sensitive homeowner data and heavy service manager loads reliably and securely. When UI/UX sees the whole system and translates it back to the engineering model, everyone wins.

“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."

from the blog: development

Humans are tool using creatures. When we want to drive in a nail, we use a hammer. When we want to dig a small hole, we use a shovel. When we want to connect something into a power outlet, we use a plug. Since there’s only one kind of hammer, shovel, or plug, it’s always easy to find the correct thing, right? Well, no, there are claw hammers, ball peen hammers, spades, shovels, 120V two-pronged and 3 pronged plugs, and those 220V plugs they use in Europe that I can never keep straight. Happily, software systems and packages don’t suffer from these incompatible interface problems, right? Of course they do. Maintaining the ability for a system or package to operate correctly against different versions and environments can be quite challenging. And testing against all of the supported versions can drive one to distraction and convince maintainers to limit supported versions to what they can deal with.
