I guide businesses to save money by guiding them with their software architecture and mobile apps. I am a Software Architecture Consultant with: ■ 20 years of experience in software engineering for mobile devices ■ 14 years of experience with Android ■ 6 years of experience with other platforms ■ 4+ years of experience in official Software Architect roles I have mentored many people in software architecture and mobile application development, such as best practices, principles, processes, and more. I created Shuttle (github.com/grarcht/shuttle), an open-source framework and solution, striking at the heart of the Android framework. It avoids app crashes caused by an uncatchable exception when data passed between screens is larger than the default limit. I led two architecture groups, leading to increased product quality, higher collaboration, and risk mitigation. I led a cross-platform/functional team to identify, plan solutions for, and remove 50% of high-priority networking bugs. I have created and implemented architectural changes and features, resulting in reducing: ■ Re-buffering percentage in streaming apps, from over 2% to 1.5% percent. These changes removed visual glitches experienced by customers. ■ Feature development time by a factor of four of the original amounts (one day down to a few hours) for multiple teams. After listening and learning about the internal and external problems you are trying to solve, I can help you identify solutions to issues and ways to help save money.
