During my time as a Google Summer of Code (GSOC) contributor, I worked on the Clang Diagnostics project within the LLVM Compiler Infrastructure. My main focus was on improving the diagnostic capabilities of Clang to enhance user experience and readability, as well as implementing new diagnostics. This work primarily involved the use of C++. Working with a team and contributing to open-source projects taught me valuable skills and knowledge. The experience of learning, coding, and interacting with the community has given me the confidence to continue contributing to Clang, especially in the area of diagnostics. Overall, it was an enriching experience.
