Projects

Memory Allocator and System Concurrency

Developed a memory allocator and system concurrency algorithms in C, including a memory allocator with a first-fit strategy and a system concurrency algorithm using semaphores.
Docker and PDF Export Service Dockerized

A simplified version of Docker was implemented using C, which advanced understanding of containerization, file system, and process management.
Machine Learing for Beginners by Microsoft

Completed Microsoft course on Machine Learning for beginners, enhancing my understanding of machine learning concepts and algorithms.
Personal Websites with Frameworks

Personal websites were designed and developed using React and Hugo, leading to improved site performance and user experience.An auto-fetch JavaScript was created to automatically pull the latest projects from GitHub and GitLab.
LLVM: Memory Leak and Array Range Overflow

An LLVM pass was developed to dynamically report array out-of-bound errors in programs written in languages such as C and C++, significantly enhancing error detection and improving software reliability.
RISC‐V Game Console

Stack and multi-thread functions were implemented for the Snake game using C and Assembly, enhancing performance on a RISC-V based simulator.
