I'm a psychologist with 5 years of experience in data analysis applied to quantitative research, descriptive and inferential statistics and data visualization. My goal is to listen to real-world problems and translate them into a data analysis project to help solve them. - Advanced level of Microsoft Excel, SPSS and Tableau. - Complete work with quantitative data: data entry and cleaning, data transformation, exploratory data analysis, group comparison, pattern identification, data visualization and interactive dashboards. - Work with any quantitative data: research data (surveys, records and measurements), business data (COGs, profits, expenses, churn), social media performance, marketing strategy evaluation, etc. - Recommendations for data-driven decision making. I'm super responsible and trustworthy, and I have great communication skills, as I've always sought to translate complex information into something more manageable and understandable for others. I'm aware of my limitations, but I constantly work on them. Currently training in PostgreSQL. If you like my profile and are interested to work with me, feel free to contact me!
