Your portfolio must include five types of projects covering five different industries, each project must clearly lay out six key elements, and you also need to demonstrate your ability to turn raw data into actionable insights.

Showcase Technical Skills and Tools

The core goal of building a job-seeking portfolio for data science is to prove that you have mastered core technical skills. You should prioritize showcasing hard skills such as Python and SQL, and can supplement them with extended skills like Power BI. You need to submit a GitHub repository with clean code and complete documentation, which helps recruiters clearly assess your abilities and practical application level.

Make Your Portfolio Recruiter-Friendly
