Foundations - Learn to Code

Before you can become a software engineer, first you need to learn to code. Our Foundations course is a structured environment where you can learn the fundamentals of coding in JavaScript, HTML, and CSS. This is ideal preparation for the Immersive interview, and a great way to try out Code Chrysalis to see if we are right for you.

Interview process

We have a multi-step admissions process and only admit students who are fully ready for our course. In this process, you will pair program with an instructor or experienced engineer during a series of technical interviews (most people do between one and four sessions). The process may be challenging but we will encourage you to continue studying and re-interview again. This is not just an entrance exam - it’s also a (free) opportunity to get advice, feedback, study guides, and hands-on practice writing code.


Precourse is a mandatory self-paced mini-course with set deadlines in the two months before the Immersive begins. These assignments are entirely different than the fundamentals in our Foundations course and cover more advanced topics that will help you start thinking like a programmer. During precourse, you will join our community, get accountability while studying, and have access to instruction staff.

Functional and Object Oriented Programming

Code in the real world is more than just data-in/data-out that you typically see in short coding tutorials. During the development of larger software projects, there will be a number of paradigms for organizing complex code you will be expected to know, including functional and object-oriented programming.

HTML & CSS (Javascript)

Regardless of what framework or backend stack your employer uses for your codebase, almost all web applications have a frontend that can be viewed by the user in a browser. HTML and CSS are the basis of all visible content on the web. We emphasize a strong foundation in these technologies to ensure that your project is functional, accessible, and visually appealing.


The days of working alone are over. Having experience working on an engineering team is crucial for job interviews. All code needs to be stored somewhere, so “source control” is the main way that engineers can work collaboratively on code. There were many “source controls” in the past, but over the last ten years, almost all companies have switched to using git.


JavaScript doesn’t limit you to just web frontend. Node is a version of JavaScript that has been "untethered" from the browser-based frontend and opens up your JavaScript skills to many more platforms and purposes. Node is commonly used for both servers and developer tooling, without having to learn any additional programming languages to get started.


Recursion is an advanced concept that is easy to skip over -  but any CS grad will have a solid understanding of this topic. It actually appears in the real world frequently, especially when dealing with file systems. Recursion is not simply a technique; it is an entirely different approach to thinking which is common in Functional paradigm code. It is also used in the ideal solutions to many Leetcode-style technical interview problems.

Immersive Course

Most courses teach students specific tools rather than how to program. However, the software industry is fast-paced and each tool becomes quickly outdated - which could make your resume worthless in less than a year. In the Code Chrysalis Immersive, we do keep the tech stacks we teach up-to-date - but we also teach solid engineering practices, historical perspective, and real priorities that will help you keep up with the industry regardless of where it goes.

In our project portion, you will build a solid portfolio of projects in the languages and tech stacks that you want to use and get practical experience working on an Agile development team. Our students have opportunities to get real world experience adding features to a live codebase, which they can draw from in interviews. Our curriculum is optimized to help you compete in an ever more competitive job market - whether you are job searching in Japan or abroad.

Data Structures & Complexity Analysis

Computer Science graduates often have a lot of experience with these topics, and because of that technical interviews test heavily for knowledge of data structures and complexity. Data these days is huge, so it’s not enough for things to just work - you also need to know how to make things work efficiently.

Agile Methodologies and Practices

Writing software in a group is different than writing software on your own. Agile is a set of industry-standard processes and practices used in professional environments to facilitate team efficiency. Experience in Agile practices (such as effective Pair Programming and Test Driven Development) is highly sought by hiring managers and recruiters to find engineers ready to be productive on their first day.

SQL, Databases, & Schema Creation

Databases can handle orders of magnitude more data than Excel spreadsheets. SQL (pronounced "sequel") is one of the most common languages currently used in modern software solutions to interact with databases, and is an in-demand skill at any company that deals with large amounts of data.

HTTP & Express

Frameworks and languages come and go, but HTTP is the basis of all communication on the internet. In addition to teaching students Express (the most common HTTP server framework for Node), we instill a fundamental understanding of HTTP itself to guarantee that they can navigate the constantly evolving world of web development for years to come.

API Architectures

Developing code in large organizations requires good communication not just between people, but between different pieces of code. APIs are the connection between large code components and learning how to develop an effective API is critical in any organization where the code you use is consumed by other teams. We teach common architectural guidelines (such as REST) for how to create a professional-quality API.

Front-end UI Frameworks

After gaining a solid foundation in HTML and CSS fundamentals and Functional/Object Oriented programming paradigms, there are many frontend frameworks to choose from. We teach a framework called React, which is the most common frontend framework currently in demand in both the Japanese market and abroad. We heavily emphasize the skills that will allow you to quickly pick up any front-end framework used at your future workplace, whether it is React, Vue, Angular, or even an in-house framework specific to your company.

CI/CD & Deployment

Writing code and building a product is only part of the product lifecycle. How does something you created on your computer get published to the rest of the world? How do you release updates? How can you be confident that the product will work after it's released? Knowledge of Continuous Integration/Continuous Delivery (CI/CD) and related workflows is a critical skill for modern development pipelines.

Programming Language Learning (”Polyglottal”)

Engineers who only know one programming language are very common, so you can set yourself apart by knowing multiple languages. During “Polyglottal” week, you will learn a second programming language (of your choosing) and build a project for your portfolio in that language. Most companies use at least two languages (sometimes more). Based on what type of company you want to work for, we will guide you to choose the best second language for your resume.

Senior Project

The Senior Project phase will give you real experience working at your own mini-startup for a few weeks. Your team will have to collaborate from project inception all the way to delivery, allowing you to encounter the realities of working on an engineering team. You can choose any tech stack for this project to build your portfolio, and get critical first hand experience with testing, documentation, and security issues. When interviewers ask, “What is a technical problem you’ve encountered and how did you solve it?” this project will be the source of your answers.

Career Support

We offer lifetime career support to our students. We will help you get your first junior engineer position, as well as helping you transition to senior roles further on in your career. Our career support process will organize and optimize your job search to help focus in on the best opportunities.
