    Check out Life Hack Innovations on Google... I am an extremely driven mobile architect with over 80 published applications worldwide, with over 1 million active users, which generated multiple millions of dollars in sales. In addition, a staggering 98% are ‘Return Users’ with a projected amount of over 10 million active users by 2025. I’ve been developing for Android over 10 years since the launch of the first commercially prominent device (G1), and have nearly 5 years of experience developing using React Native with more limited experience in Windows, Mac OS, Linux, and low level C. With a degree in Electrical Engineering, some of my most prized applications have been in IOT where I’ve developed apps that utilize Bluetooth, Wifi, RFID, Maps, and various other highly popular technologies. I own and operate a small application development company that produces significant measurable results. The average growth rate of my latest client (sls.com) has shown approximately 40% growth month after month for the lifetime of the application (~1 year), and has led me to become part owner of the largest global couples dating app in the world. Along with applications published to the app stores, I’ve produced Enterprise applications for several Fortune 500 Companies including Trimble, Assurant, Target, SATO Global Solutions and government entities including the FCC (Federal Communications Commission), and more recently DHS (Department of Homeland Security) with the intent to help prevent the spread of COVID-19. I am extremely detail oriented and make it my goal to deliver high quality, polished applications that exceed my clients needs with added focus on detailed analytics, cloud integration, continued customer support, and consistently high quality UI/UX.
