About

🚀 MSc Advanced Computer Science Student at the University of Oxford | Artificial Intelligence Stream | Software Engineer I’m a software engineer and computer science graduate from the University of Bucharest, now pursuing an MSc in Advanced Computer Science at the University of Oxford. I’ve completed software engineering internships at Jane Street in London, where I worked on improving the performance of critical strategy code and building tools to improve trading workflows. Previously, I gained experience developing ERP software with Python and Odoo at Diginesis, and building a performance-optimized data compression tool in C/C++ at NetLup Technologies. My academic interests include machine learning, financial markets, systems, and software engineering. For my BSc thesis, I worked on HouseCFG, a project focused on indoor housing plan generation via diffusion models. I graduated from the University of Bucharest with a 9.78 GPA and was an honors student with a performance scholarship. I also have a strong competitive programming and robotics background. I earned multiple awards at the Romanian National Olympiad in Informatics, including one silver medal and three bronze medals, and led a First Tech Challenge robotics team that won multiple national awards and qualified for the Chicago Robotics Invitational. 📬 Contact Email: [email protected] Website: https://mariodeaconescu.com
