You will get clean data, insights and visualizations from your dataset
Project details
You will get a clean, structured, and analysis-ready dataset delivered with clear insights and professional documentation.
I specialize in data cleaning, preprocessing, and exploratory data analysis using Python, PySpark, and Excel. With an academic background in Data Science and a Master's degree in Artificial Intelligence in progress, I focus on transforming raw and messy datasets into reliable information that supports better decision-making.
My workflow includes data understanding, cleaning, missing value handling, duplicate removal, feature engineering, statistical exploration, and visualization when required.
This project is ideal for researchers, startups, analysts, and businesses that need organized data and actionable insights without spending hours preparing datasets.
✔ Clean and structured datasets
✔ Clear analytical insights
✔ Reproducible notebooks and well-documented work
✔ Professional communication and fast delivery
Let’s turn your raw data into valuable information.

About Diogo
Data Analyst | Python Data Cleaning, EDA & Predictive Modeling
Setubal, Portugal - 4:16 am local time
I enjoy working with data to solve real problems - from cleaning messy datasets to building clear analyses and predictive models that help decision-making.
I mainly work with:
- Data Cleaning & Preprocessing
- Exploratory Data Analysis (EDA)
- Data Visualization & Insights
- Machine Learning & Predictive Modeling
- Dataset preparation for AI/ML projects
I hold a Bachelor’s degree in Data Science and I am currently completing a Master’s in Artificial Intelligence, where I work with real-world datasets and industry-style projects (including CRISP-DM workflows).
I focus on writing clean Python code, structured analysis, and making data understandable — not just for technical teams, but also for business decisions.
Tools I use regularly:
Python (pandas, numpy, scikit-learn), SQL, and data visualization libraries.
If you need someone reliable to clean, analyze, or help make sense of your data, feel free to reach out.
