- Contributed to the development of the recent release of .NET Framework 4.8.1, which also provides native ARM64 runtime support. As part of the deliverables, I ported some highly desirable features from .NET Core, provided improvements to the internal infrastructure of the codebase to aid with the development and testing of the product, and worked with the Windows team to ensure a seamless incorporation of the new framework with the operating system.- Provided enhancements to the .NET runtime used in Docker Containers. Added the functionality to allow users to define how many processors to allocate for the container, and led the development of ASP.NET Core composite images. Measured multiple scenarios for accurate benchmarks to identify key areas of performance improvement, and contributed to reducing the size of the images while keeping the performance gains.- Added a new API to the .NET runtime that allows the user to set the entry assembly of the application at runtime, instead of relying solely on what is set automatically when the app is launched. This facilitates the implementation of launcher apps and services like some found in Azure servers.- Provided various improvements and bug fixes to the .NET runtime.

- Helped develop an infrastructure measuring tool to gather performance benchmarks of the Garbage Collector in .NET Core and .NET Framework. Implemented a few enhancements to make it more reliable and easier to use, as well as a new feature to be able to benchmark Pinned Object Heap objects starting from .NET Core 5.- Provided various enhancements to the .NET Core build and test infrastructure to improve the developer experience. Added more thorough checks to alert the user about potentially bad inputs on time, as well as laid the groundwork for the runtime tests to work under a new unified system.
