Former Oracle SQL Developer — Beginner-Friendly SQL Tutoring

Wilma M.

I hold a Bachelor’s degree in Computer Information Systems and have professional experience as an Oracle SQL Developer in data warehousing and reporting. In this role, I worked daily with SQL to build queries, manage data, and develop reports that supported business decisions. My academic background gave me a strong foundation in databases and programming, while my professional work allowed me to apply those skills to real-world projects. This combination of education and experience enables me to explain SQL in a way that is both practical and easy to understand.

Although I have not been a classroom teacher, I have extensive experience mentoring coworkers and junior team members. I often helped colleagues troubleshoot queries, understand relational database concepts, and improve the efficiency of their SQL code. These experiences taught me how to break down complex topics into clear, step-by-step explanations that make sense to beginners. I am patient, approachable, and committed to making students feel comfortable asking questions and practicing until they gain confidence.

My tutoring approach is student-focused and hands-on. I begin by identifying a student’s goals, whether it is passing a college database class, preparing for an interview, or learning SQL from scratch. From there, I tailor lessons to their level and use a combination of explanations, guided practice, and real-world examples. My emphasis is on SQL fundamentals such as SELECT statements, filtering, JOINs, GROUP BY, and window functions. By keeping lessons practical and interactive, I help students build both understanding and confidence so they can apply SQL in their studies or careers.
