About Me

I am a data analyst with a multidisciplinary background that combines critical thinking, clear communication and the ability to structure information in a logical, results-oriented way. My experience as a writer, teacher and web developer strengthens the way I interpret data, turning it into useful knowledge adapted to each client's real context.

I completed the IBM/Coursera Data Analyst Professional Certificate and specialized in SQL, Python, Power BI, Excel and data visualization. I work on end-to-end processes of data collection, cleaning, transformation and exploratory analysis, creating dashboards and reports that provide clarity, support decisions and reveal improvement opportunities.

I develop practical and accessible solutions for small businesses, professionals and organizations that need to organize their data, better understand their indicators and make decisions based on evidence. I value ethics, accuracy and simplicity, delivering analyses that combine technical rigor and objective communication.

My goal is to help each client turn data into clear insights, more efficient processes and safer decisions.
