Xue-lei Andrew Fan

Worked on the SAP/SapMachine repository to address a critical memory management issue in the CDS archive, focusing on scenarios involving large class sets. Using C++ and Java, implemented a robust mechanism to support larger metadata offsets, which eliminated out-of-memory errors during class data sharing operations. The solution improved memory efficiency and stability for enterprise workloads that rely on extensive class metadata. Collaborated closely with peers through clear code reviews and a focused commit process, demonstrating expertise in system programming and memory management. This work enhanced the reliability and scalability of SapMachine deployments, reducing memory pressure and crash risk during CDS processing.
