Software development
Mobile application development
A phone or a scanning gun that does a job on the floor, from works orders and timesheets to warehouse stock and blood tracking. Mobile software earns its keep when the network drops and it keeps working.
Phones and tablets
iPhone and iPad work since 2009, including industrial-scale mobile works-order systems and timesheets. Native in Objective-C, Swift, or .NET, or hybrid when the brief calls for it.
Ruggedised hardware
Windows CE devices with tiny RAM and part-time networks are how the warehouse and hospital jobs were done, and they taught us to design for the moment the radio goes quiet.
