Welcome to my portfolio. I am an independent researcher working at the intersection of cybersecurity, artificial intelligence, blockchain systems, and human-computer interaction. My work focuses on building trustworthy and practical intelligent systems.
About Me
I am an independent researcher and computer science engineer working at the intersection of cybersecurity, artificial intelligence, blockchain systems, and human-computer interaction. My work focuses on building trustworthy and practical intelligent systems, particularly in areas such as large language models, XR/VR systems, and decentralized technologies.
Previously, I worked as a software engineer at Brain Station 23 PLC and Apsis Solutions Ltd., where I led and contributed to the development of large-scale cross-platform applications, AI-driven solutions, and enterprise mobile systems used in production environments. My engineering background spans mobile systems, machine learning applications, and scalable software architecture.
Currently, I collaborate on research projects with international researchers, including work with the University of Texas at San Antonio, exploring topics such as cybersickness detection in VR, security of blockchain rollups, trustworthy evaluation of medical LLMs, and prompt injection detection. My research has been presented at conferences including ICECE and EICT, with ongoing work targeting venues such as USENIX and ACM FAccT. Alongside research, I am actively involved in building and supporting technology-driven ventures in the software and tech industry.
