As an intermediate data analyst with expertise in data scraping, analysis, predictive tools, and visualization, I have a range of skills and knowledge that I can bring to any project. My work focuses on five key themes: data collection, data cleaning and preprocessing, data analysis, predictive modeling, and data visualization.
In the area of data collection, I am experienced in web scraping and API integration. I am skilled in using Python and R to extract and manipulate data from a variety of sources, including websites, databases, and social media platforms.
When it comes to data cleaning and preprocessing, I am familiar with a range of techniques, including data imputation, outlier detection, and feature scaling. I have experience working with large and complex datasets and am skilled in using tools such as pandas, NumPy, and scikit-learn to preprocess data for analysis.
In terms of data analysis, I have experience using a range of statistical and machine learning techniques, including regression, clustering, and classification. I am familiar with tools such as Tableau and Power BI for data exploration and visualization.
In the area of predictive modeling, I have experience building and evaluating models for a variety of applications, including customer churn prediction and fraud detection. I am skilled in using tools such as TensorFlow and Keras to build deep learning models and have experience with techniques such as cross-validation and hyperparameter tuning.
Finally, in the area of data visualization, I am experienced in creating clear and effective visualizations that communicate complex data in a way that is easy to understand. I am familiar with a range of tools, including Matplotlib and Seaborn, and am skilled in using visualization techniques such as scatterplots, histograms, and heatmaps.
Overall, as an intermediate data analyst with expertise in data scraping, analysis, predictive tools, and visualization, I have a range of skills and knowledge that can be applied to a wide variety of projects. Whether it's collecting and preprocessing data, analyzing it using statistical and machine learning techniques, building predictive models, or visualizing the results, I am well-equipped to handle the challenges of any project.
