Defining problems through psychometrics, validating assumptions through data, building solutions through software engineering, and managing risks through cybersecurity.

I am an educational technology and psychometrics specialist with a master's degree in educational information and measurement.

My academic and professional interests include:

• Cognitive Diagnostic Models (CDMs)
• Item Response Theory (IRT)
• Classical Test Theory (CTT)
• Q-Matrix and Q-Tensor analysis
• Educational data analysis
• Learning analytics
• Assessment system development

In software development, I use PHP, Laravel, Python, and R to build educational applications, automate research workflows, and analyze assessment data.

I also have training in cybersecurity and apply secure design principles to web applications, data processing workflows, and educational information systems.

With an academic background in music and professional experience in education, I am particularly interested in interdisciplinary applications that connect psychometrics, software engineering, music cognition, and educational practice.
