What I'm looking for

I am seeking an entry to mid-level data role where I can apply Python, SQL, and visualization skills, contribute to predictive projects, and grow in a collaborative, data-driven team.

I am an data scientist with a strong foundation in data analysis, machine learning, and programming, backed by customer-service experience spanning over a decade. I recently completed the IBM Data Science Professional Certificate and have hands-on experience in Python, SQL, data visualization, scikit-learn modeling, and dashboarding.

I have applied my skills in simulations and capstone work — building predictive models, scraping and analyzing review data, and producing dashboards for actionable insights. I combine analytical rigor, multilingual communication, and proven accuracy in data entry and recordkeeping to deliver reliable, data-driven solutions.
