Brazil

Data Analyst | R & Python Expert for Medical & Biological Research

プロフィール概要

I’m a data analyst and programmer with expertise in Python and R, focused on supporting doctors, biologists, and researchers in making sense of complex datasets. I help translate raw data into clear, statistically sound insights — whether for academic publications, research projects, or clinical studies. I specialize in data cleaning, statistical analysis, and visualization, using libraries and tools like pandas, NumPy, matplotlib, seaborn, ggplot2, and dplyr. I’m comfortable working with experimental data, clinical observations, and biological datasets, and I prioritize clarity, reproducibility, and precision in every project. With a strong background in research, I understand the standards of scientific work and the importance of presenting data clearly and accurately. If you're looking for someone to help analyze, interpret, and visualize your research data using Python or R, I'm here to help.
