Welcome to my portfolio!

I'm a data analyst with a PhD background in education and seven years of teaching experience. I’m passionate about using data to uncover insights, tell meaningful stories, and support informed decision-making that drives positive impact.


Skilled in SQL, Python, R, and Tableau, I focus on data wrangling, visualization, and reporting to uncover trends and drive improvement. My education background strengthens my ability to interpret data critically and communicate insights clearly to diverse audiences. I’m always eager to learn, collaborate, and use data to create positive change.


I'm enthusiastic about new opportunities to apply my skills.
