I am an experienced VBA developer with a deep understanding of Microsoft Access and database management. Over the years, I have built efficient, scalable solutions that streamline data processing, automate workflows, and enhance business operations. My expertise lies in designing structured, optimized databases that ensure seamless data retrieval and manipulation. One of my key strengths is breaking down complex problems into logical, manageable steps. Whether it’s designing relational database structures, optimizing queries, or automating reports with VBA, I focus on creating solutions that are both powerful and user-friendly. I teach my students how to visualize code execution, ensuring they understand how each function interacts within the database before implementation. My structured six-lesson series is designed to equip students with the skills needed to confidently work with Microsoft Access and VBA. From designing tables and queries to automating processes with macros and custom functions, my approach ensures students gain practical, real-world experience. If you're looking for a tutor who can simplify VBA and database management, enhance problem-solving abilities, and help you master Microsoft Access, I’d love to work with you!

Programming class overview
Mastering VBA and Microsoft Access requires more than just learning syntax—it’s about designing efficient, scalable database solutions. My tutoring approach focuses on problem-solving, code design, and real-world application, ensuring students gain practical skills that translate directly into professional environments. I structure my lessons around three key steps: WHAT, WHY, and HOW. WHAT – We define the problem and identify the business rules shaping the project. A well-structured database starts with clear objectives, ensuring every table, query, and function serves a purpose. WHY – We analyze the reasoning behind each design choice. Understanding why certain database structures and VBA automation techniques are used helps students develop a strategic mindset, making their solutions more effective. HOW – Finally, we focus on execution. With the what and why established, we confidently implement VBA code and database structures optimized for performance and scalability. I foster a relaxed, interactive learning environment where students feel comfortable asking questions and exploring creative solutions. My lessons are project-based, centered around topics that genuinely interest each student—whether it’s automating reports, optimizing data entry, or designing relational databases in Microsoft Access. By prioritizing code design first, students learn to visualize how their VBA code interacts with the database before writing it. This leads to cleaner, more efficient programs that withstand real-world demands. My goal is to help students master Microsoft Access and VBA, ensuring they can confidently build professional-grade database solutions. Let’s create something powerful together!

Computer Science concept taught by Steven
Steven assisted Jean in organizing her property expense data using Excel. They focused on importing information from a disorganized spreadsheet into a new template, employing copying, pasting, and sorting techniques to identify missing details. Steven will send Jean the completed Excel template for her to begin using and entering her 2025 data.
Data Sorting & Filtering
Separating Data Types
Autofill & Pattern Correction
Quick Data Selection (Ctrl+Shift+Arrow)

Steven assisted Bol with a Python assignment focused on calculating and plotting V2 max levels for cyclists based on training hours. During their lesson, they defined a function, created a plot with labeled axes and a legend, and discussed the application of for loops and conditional statements within the programming language. Bol will send Steven a different file for their next lesson, where they will continue working on Python problems.
For Loops
NumPy Arrays (Vectors)
Matplotlib Plotting
Python Functions
Steven and Bol collaborated on a Python coding problem, focusing on temperature data. They developed a function to calculate and plot daily temperatures for Melbourne and New York, utilizing Matplotlib to visualize the information and identify minimum temperatures. Bol was encouraged to review the code and make notes on any unclear sections for a future discussion, with another lesson scheduled for the following day to tackle tasks four and five.
Python Function Definition
List Append Method
Matplotlib Plotting
List Indexing
Steven and E T collaborated on structuring VBA code for data import, cleaning, and analysis in Excel. Their lesson covered array manipulation, variable passing, and debugging techniques for this Excel VBA utility. Steven tasked E T with running the code to test its functionality and will send the updated file.
ByRef vs. ByVal
Redim Preserve

Subscript Out of Range Error
Subroutine vs. Function
Steven and a learner from Cosumnes River College in Elk Grove worked on creating flowcharts for code snippets and tracing code execution. They analyzed a menu-driven program and a program that checks for even numbers, focusing on conditional statements, error handling, and code readability. The learner practiced tracing code execution with specific inputs and numbering the executed lines.
Python Try-Except Blocks
Flowchart Divergence
Integer vs. Float
While Loop Execution
Function Call & Return
Steven and Bol reviewed Python code execution, focusing on creating flowcharts and numbering lines of execution. They analyzed code snippets with loops, conditional statements, and function calls, tracing the order of execution based on inputs and console outputs. They plan to continue their work on these types of Python exercises in the next lesson.
