There's a project in my portfolio in which I did a sentiment analysis of the 2020 news, you can take a look at it if you want to know what I'm able to do.

San Bernardo, Chile - 10:48 pm local time
My work is a strong fit for teams that need to build internal tools, automate analysis, clean and structure complex datasets, or turn raw data into clear reporting and forecasting.
I work mainly with R, Shiny, Python and Quarto/R Markdown, and I can support projects such as:
- Custom R Shiny applications
- Interactive dashboards and reporting tools
- Automated data cleaning and reporting workflows
- Statistical analysis and forecasting
- Predictive modeling and machine learning
- Text analysis / NLP for research and business use cases
I’m comfortable taking projects from data preparation to final delivery, including analysis, app development, visualization, and reporting. My background includes work in public policy, applied analytics, predictive modeling, and custom tools built for real decision-making.
If you need help with an R Shiny app, dashboard, automated reporting workflow, forecasting project, or custom data analysis, I’d be glad to discuss your project.
