Hi, I’m James! I tutor mathematics, computer science, data analysis, and securities exam preparation. I earned my bachelor’s degree in Computer Science from California State University, Fullerton, and currently work as an Imaging Research Specialist at Barrow Neurological Institute.

I can help with algebra, calculus, statistics, Python, R, Bash, data analysis, programming fundamentals, and general computer skills. My approach is patient and practical: I break difficult concepts into manageable steps, work through problems with you, and focus on building the understanding and confidence needed to solve similar problems independently.

I also specialize in the SIE and Series 63 exams. I passed both on my first attempt and previously worked as a Client Service Associate at Morgan Stanley, giving me firsthand exam knowledge and practical financial-services experience.

For securities students, we can cover investment products and risks, market structure, customer accounts, regulatory agencies, prohibited practices, state securities laws, registration requirements, fiduciary responsibilities, and ethical practices. We can also review missed practice questions, identify patterns in your mistakes, and create a focused study plan based on your exam date.

Every lesson is personalized around your goals, current level, and learning style. Whether you need ongoing course support, help with a specific assignment, stronger technical skills, or focused exam preparation, we’ll concentrate on the areas that will produce the most improvement.

Send me the subject you’re working on, your current level, and what you’d like to accomplish, and I’ll help you determine the best place to start.
