Getting into the field of data science makes developers and data enthusiasts question about how they can build their career. Becoming an expert in the field requires hours, days, and months of practice and experimentation with various codes, projects, and data already available on the internet.

Landing a job as a data scientist begins with building your portfolio with a comprehensive list of all your projects. To start building projects, developers search for platforms and websites that can help them learn from experts while also collaborating and experimenting with real world applications. 

To help you get started with building your portfolio, we have listed the top platforms for you to get noticed by recruiters and get hired in data scientist or analyst profiles. These platforms can expand your knowledge about data science while simultaneously helping you put together your portfolio through interactions with experts and building projects.


As a data scientist, building a portfolio on GitHub is one of the several ways to get noticed. Recruiters and hirers are likely to look at your GitHub profile and review your recent projects before asking you questions about the role.

As of June 2022, the GitHub community had nearly 83 million developers and at least 200 million repositories. It is probably the largest source for code in the developer community. By pinning your projects on top and building a great profile, you can attract numerous recruiters and desired job roles.
