About me...

Welcome to my website! I'm a passionate software engineer with a strong foundation in computer science. In 2023, I successfully completed my Bachelor of Science degree in Computer Science from University College Cork (UCC). During my time at UCC, I had the privilege of serving as the Chairperson and SysAdmin of a thriving college society called Netsoc. As part of this role, I had the opportunity to immerse myself in the world of gaming, networking, and technology, fostering a vibrant community and organizing various engaging events. One of the highlights of my academic journey was my bachelor's thesis titled "Evaluating Performance of HTTP/3 for Video Streaming: A Comparative Study with Previous Versions of HTTP." This research project not only challenged me intellectually but also allowed me to delve deep into the fascinating realm of video streaming and the evolution of web protocols. I'm proud to share that my thesis received a First Class Honors grade, a testament to my dedication and commitment to excellence. Throughout my academic pursuits and experiences as a software engineer, I've developed a strong skill set encompassing various programming languages, software development methodologies, and problem-solving techniques. I am passionate about creating innovative and efficient solutions that make a positive impact in the ever-evolving digital landscape. I created this website as a platform to showcase my projects, share my knowledge and insights, and connect with like-minded individuals.
