Aggressively converting many hundreds of existing Windows projects to use the Universal C Runtime Libraries (UCRT) across the entire Windows domain.This project takes full advantage of my in-depth and long-held knowledge of the CRT and other C++ libraries (MFC, ATL, iostream.h, and STL), as well as the Microsoft Windows code base and proprietary Build System. In addition to converting the build system, I updated hundreds of source files to use the modern C++ language and STL features.I also used the proprietary Windows Component Database (WCD) using C# to analyze dependencies to accurately determine which components needed to be converted as a group and where tradeoffs could be made. Overall, created about 50 often complex PRs in 5 months across dozens of teams.

Primarily developing apps, initially for the iPhone, to (for example) share AI-generated “hockey stick” stock market predictions. Also managing all infrastructure and software resources on the non-AI side of the company, including GitHub for the team; Google Cloud Integration and scheduling dozens of daily and weekly model runs, organization of cloud storage, Firebase app storage, etc.

Took some time to update my skills, organize my life, and prepare for the next career steps. Preparing to start a new project!
