I hold a Master of Science degree in Computer Science from Western Illinois University, where I also served as a Graduate Assistant. During this role, I provided one-on-one and small group tutoring support to undergraduate students in core computer science courses such as programming, data structures, and systems analysis. My academic foundation, combined with industry-recognized certifications—including the Microsoft Data Analyst Associate and Google Certified Data Analyst—has allowed me to teach both theoretical and practical aspects of computing and data analytics.

Over the past four years, I have extended my teaching experience through other tutoring platforms, where I have worked with high school, college, and adult learners. I tailor my approach depending on the student’s background, using real-world analogies, interactive coding sessions, and guided problem-solving to build conceptual clarity and practical confidence. My teaching style emphasizes patience, active listening, and the use of formative feedback to ensure measurable progress. I’ve also supported learners preparing for technical certifications and those transitioning into data and tech careers.

In addition to my tutoring, I bring experience from my professional roles as a Product Owner and Data Analyst, which enriches my ability to teach subjects such as SQL, Python, Power BI, and systems development. I enjoy bridging the gap between classroom learning and real-world applications, especially for learners seeking to apply their knowledge in professional or academic settings. This mix of academic rigor and hands-on experience makes me confident in supporting students across a variety of skill levels and learning objectives.
