What I'm looking for

I am looking for a role in a data-driven team that values collaboration and innovation, where I can apply my analytical skills and continue to grow professionally.

I am a motivated and detail-oriented aspiring Data Analyst currently completing a Data Science program through ALX. My hands-on experience includes working with Excel and Google Sheets, where I have successfully annotated and evaluated datasets to enhance machine learning models. Recently, I led a project analyzing water access and AI behavior data, where I cleaned and transformed messy datasets to generate impactful insights using pivot tables, scatter plots, and histograms.

Throughout my career, I have collaborated with QA teams to refine AI systems and improve model accuracy through structured analysis and real-time feedback. I am actively building my technical skills in SQL, Python, Machine Learning, and AWS, with a strong focus on using data to tell clear, actionable stories. I am eager to contribute my analytical skills and learning mindset to a data-driven team.
