Data Science Portfolios can be built through Kaggle Competitions. Kaggle has positioned itself as the premier data science platform for learning.
Kaggle is a crowd-sourcing platform in which companies post their real-world data science problems in an effort to solve their problems. Kaggle will host Kaggle competitions to the public and rank the participants against one another. When large companies need help with their data science challenges, they turn to Kaggle and its community for help.
The famous $1 million dollar Netflix challenge was originally a Kaggle competition. Other companies who are leveraging the Kaggle competitions to address business solutions are:
Allstate, Bosh, State Farm, Red Hat, Facebook, Expedia, Home Depot, Yelp, Airbnb, Walmart, and Liberty Mutual.
The Future of Kaggle as a Data Science Platform for Hiring and Learning
To be hired as an artist or an architect, you need to present a portfolio which showcases years of your work. Programmers need a Github/StackOverflow account to showcase their contributions. Similarly, Kaggle is positioning itself in the same way for any data vocation. The litmus test to be hired as a data scientist gets another hoop.
Kaggle has spent the last half decade positioning itself as the premier platform for hiring, recruiting, and screening for data science talent. Companies and recruiters get a transparent record of your performance, a paper trail of your successes and failures, and most importantly, your growth–all of which is tracked in a quantifiable manner.
Employers want to see whether a candidate has been battle-tested in data science through these competitions.
To you as an individual, this is a chance to participate and compete in Kaggle against others like you from around the world, prove to employers and recruiters that you have some hands-on experiments under your belt, and that you are worthy of the title of data scientist.
How do I Compete? Where do I Start?
The best way is just to dive right in. Be warned that you are competing against people from all over the world. Your first submission scores will be demoralizing. However, do not give up as each failed attempt will shape you into a better data scientist. To fail in Kaggle competitions is not only a good thing, but is desired. Employers want to see your growth and better yet, your potential to overcome your challenges.

Kaggle and Data Science Dojo
Data Science Dojo hosts a Virtual Data Science and Data Engineering bootcamp to expose people to the entire breadth of data science. Bootcamp attendees are required to participate in a Kaggle capstone project that spans the length of the course.
The end goal of the project is to take what you’ve learned each day and apply it to your model. Each attendee takes what they learned during the day and applies it to their Kaggle models. At the end of the Bootcamp, the top 3 performers receive a prize.
