Predicting Developer Salaries

The 2023 Stack Overflow Developer Survey captured tens of thousands of responses describing skills, experience, location, work preferences, and compensation. Your job is to turn that raw, messy dataset into a linear regression model that predicts yearly salary and reveals the factors behind developer pay. You'll work through a full data science workflow: auditing and dropping sparse columns, filtering outlier salaries, engineering features from multi-select skill lists, encoding high-cardinality categories, and managing multicollinearity before training and evaluating your model. Along the way, you'll interpret coefficients to separate controllable factors like skills and role from fixed ones like geography. Build and evaluate a linear regression model on Stack Overflow survey data to predict developer salaries and surface the factors that drive compensation.
