Your data science portfolio is one of the most important tools you have to showcase your skills and experience to potential employers. But how can you be sure that your portfolio is up to snuff? In this blog post, we'll go over a few key indicators that will help you assess the quality of your data science portfolio.

Does your data science portfolio show off a variety of skills?

As a data scientist, you should have a pretty diverse skill set. And your portfolio should reflect that. Employers will want to see that you're not only proficient in statistical analysis and data visualization, but also in things like machine learning, natural language processing, and deep learning. If your portfolio only focuses on one or two of these areas, it might not be strong enough to impress potential employers.

Is your data science work well-documented and easy to follow?

When employers are looking at your data science portfolio, they're not just interested in the results you achieved—they're also interested in the process that got you there. That's why it's important to make sure that your work is well-documented and easy to follow. Include clear and concise explanations of the methods you used, as well as links to any code or notebooks you used in your analysis. This will give employers a much better sense of your thought process and abilities.

Have you included real-world examples?

The best way to show off your skills is by including examples of projects you've done in the real world. If all the work in your portfolio is from school assignments or contrived examples, it's not going to hold much weight with potential employers. Be sure to include at least a few examples of projects you've done for actual clients, businesses, or pro-bono. This will show that you have experience applying your skills in the real world—which is what employers are really looking for.


If you're wondering whether or not your data science portfolio is up to snuff, I suggest you submit it to a career coach for professional review. Remember, employers are looking for a balance of technical skills and real-world experience—so be sure to showcase both in your portfolio. With a little bit of effort, you can be confident that your portfolio will help you land the job you want.
