I hold both a Bachelor’s and a Master’s degree in Computer Science from Drexel University, where I graduated with high honors. Over the past seven years, I have built my career as a Data Engineer and Software Developer, working extensively with Python, SQL, and cloud technologies like AWS. In my professional role at Vanguard, I design and maintain large-scale data pipelines, develop web applications, and mentor junior developers on best practices in programming and data engineering. These experiences have given me a strong foundation not only in technical problem-solving but also in teaching complex concepts in clear, approachable ways.

Tutoring is a natural extension of the mentoring I have done throughout my career. I have worked one-on-one with interns, guiding them through Python programming, data analysis, and workflow design. My approach focuses on breaking down challenging material into understandable steps and adapting my teaching style to match each student’s learning pace and goals. I’ve seen firsthand how patience, real-world examples, and structured practice can help students build confidence and mastery in subjects that once felt overwhelming.

I specialize in tutoring Python, SQL, computer science fundamentals, and data analytics. Whether you are a high school student exploring coding for the first time, a college student tackling advanced computer science coursework, or a professional seeking to strengthen your technical skills, I tailor lessons to meet you where you are. My goal is not only to help you succeed in your current courses or projects but also to give you skills you can confidently carry into the future.

Computer Science

I am an experienced computer scientist with a strong background in software development and data engineering, specializing in Python and AWS cloud services. I have designed and implemented scalable data pipelines, automated workflows, and real-time dashboards that improve data accessibility and quality. My work includes mentoring junior engineers and interns, sharing best practices in coding and data pipeline development. I am passionate about leveraging technology to solve complex problems and help others build their technical skills.
Data Analysis

Data Analysis

I'm currently a Data Engineer that supports many data scientists and data analysts by supplying them with clean and accessible data. I'm advanced in Python and Polars for data cleaning and transformations. And I'm experienced with creating data apps with Streamlit and working with Jupyter Notebook/Lab.
