Multiple tracks. What's your experience level?


A great first-step for students who have not coded beyond college assignments.
This is the right track for you if you're a college student who has completed some CS classes but hasn't built anything independently and without step-by-step guidance.
You'll be matched with a mentor from the technology industry, like at most traditional internships, and will make a tiny first contribution to OSS.
(By invitation only.)

Intermediate Track

More guided projects for college freshmen/sophomores/juniors to help develop engineering mindset.
This is the right track for you if you're a college student who has completed 101/102-level CS classes but not much more (or a high school student who's participated in hackathons).
You'll be matched with a mentor from the technology industry, like at most traditional internships, and will build a polished app/feature.
(No fee. Not a paid internship.)

Advanced Track

For college juniors/seniors with more CS knowledge, but without the time for a full-time internship.
This is the right track for you if you're a college student with experience beyond the 101/102-level CS classes, or a student who has built projects on your own time (e.g. hackathons).
You'll be matched with a mentor from the technology industry, like at most traditional internships, and will build a polished app/feature.
(No fee. Not a paid internship.)

If you get stuck, our TAs are always available to help!

We've helped thousands of students get their start in technology since 2009.

As an international student in a programming major, you guys totally helped me to start my wonderful career path! In a three years degree, I had you guys as my first experience, Meta as my second, and Microsoft as my third, and this last one gave me a full time return offer.
Luiza Cartaxo, Labs Advanced-Track
I loved being able to work as a team and gain real world experience about coding but at the same time also having the opportunity to learn something new.
Kelly Dong, Labs Advanced-Track
Being a Venezuelan immigrant, Labs was the first time that I got true exposure to a community of tech people that I could rely on. Fast forward a couple of years and now I'm three and a half months away from graduating college and have a job as a SWE at the Microsoft HQ right after I graduate.
Daniel Lobaton, Labs Beginner-Track
I began my CodeDay Labs internship with no background in using React Native, but came out of this internship knowing the ins and outs of React Native thanks to my team and my mentor, Eric. I highly recommend CodeDay Labs as a chance to apply your knowledge to real-world applications
Vivian Wang, Labs Beginner-Track
I really enjoyed learning how to use new technology such as Angular, Node, Sequelize, and Joi. Working with my teammates and interacting with each other was one of my favorite parts of this internship. Just helping each other out, working, learning, and growing together as developers was really great. Also the mentor was very helpful.
Alain Nshimirimana, Labs Advanced-Track
My experience as a CodeDay Labs intern certainly exceeded my expectations. My favorite part about being an intern was getting to learn and work with Python Django. I found working with Django to be difficult yet also fun. At the beginning of the internship, because I only had experience with ReactJS, I thought I would only be working on the frontend component of the app which we built. However, I ended up only working with ReactJS (i.e. the frontend) for about a week before I became responsible for the backend. I'm really glad I got this exposure because I found that I enjoy working with backend-related stuff.

Advanced Track

Mentor: Yang Xu, Engineer at LexisNexis Risk Solution
We will design a system to fetch data from REST api and store data in a database. The system is comprehensive with various functionalities such as input/output, caching, logging, etc. The system has to be highly scalable so that it could handle big amount of data.

Alexandrie-Based Rust Crate Registry
Advanced Track

Mentor: Ankit Gupta and Kat Ngov, Lead at Transparent Systems
#rust #rustlang #OSS #cloud #docker #kubernetes #k8s is the default, public package registry used by rust developers everywhere.

Developers often want the means to privately publish crates (rust packages), so they can continue to follow best practices to version and release software internal to their teams or businesses.

Current solutions for a private crates registry are hard to find and very costly. However, there exists an open source implementation of the crates registry API one can easily run on their local machine - "Alexandrie" at

In this internship, we will build on Alexandrie to provide an open-source solution that others can use to more easily deploy a private crates registry to cloud providers.

We will be using docker, and developing the reference solution to be deployable to a Kubernetes cluster in one of the major cloud providers (Azure, GCP, AWS).

In addition to developing a solution others can use, we'll learn how to use Kubernetes to deploy, scale, and manage applications.

Join this project to work with great cloud tooling and contribute to the growing and exciting Rust ecosystem!
