    “I sought Goldenwork99's services for Android and iOS application development. The developer is creating an application that connects to a newly developed Bluetooth device. With this being our first time ever creating an app - Goldenwork has done a golden job of guiding us. Golden has shown diligence and patience with us throughout this new endeavor. They have been graciously forthcoming with sharing their expertly advise. Unlike other providers, they are delivering what WE want, opposed to what THEY want - we all there's a difference. Should any questions or challenges arise - they've contacted me to discuss and when we have questions, they have been prompt with their responses. Thus far, everything is going according to schedule and possibly, ahead of schedule. Not only would we recommend this development team - we are going to rehire them!”
