I am a Data Analyst with over 7 years of experience in R programming. I have hands-on expertise in data preprocessing, exploratory data analysis, and building statistical and machine learning models. My toolkit includes linear and logistic regression, time series models (ARIMA, SARIMA, Exponential Smoothing), decision trees, random forests, support vector machines (SVM), gradient boosting (XGBoost, CatBoost), k-means and hierarchical clustering, PCA, and ensemble techniques. I am also proficient in data visualization using ggplot2, plotly, and shiny for interactive dashboards. Skilled in writing reproducible and efficient R scripts for end-to-end data workflows.
