    👋 Hey there! I'm Sumukh, the author of this course

    I work at AngelList and previously helped teach Python and Flask at U.C. Berkeley to thousands of students. I've helped a lot of people learn Flask but along the way I noticed a problem with the tutorials and books that people were using.

    The problem was that tutorials would skip the actual problems you would encounter as a full-stack developer trying to deploy a maintainable and scalable application in production.

    To solve this this problem, I decided to create this course: A guide that doesn't just cover the basics, but one that teaches how to solve all of the problems you will run into when developing a web application using Flask.

    It's the guide I wish I had when I was getting started, and I think you're going to love it.

    What We Will Build

    In Fullstack Flask I will teach you how to use the full power and expressiveness of Python to build a fully functional income-generating web app from scratch using Flask.

    Introducing Yumroad

    In this course, we'll build Yumroad: a service for selling digital products online

    Real-world architecture

    We're not going to build a simple web-server and be done with it - no way. Instead, we're going to build out the full architecture of a real-world app. That means, databases, delayed jobs, sending emails, monitoring performance, and a whole lot more.

    Payment Forms and Webhooks

    We'll implement custom payment forms -- and implement the server hooks to make them work

    Stripe Integration

    We'll integrate with Stripe to handle payments for our digital products

    Send emails

    Our applications often have to email users and in this course, we'll show you how to do it

    Work with APIs

    We'll work with third party APIs to get real world data and bring it into our application.

    Fullstack Flask vs. Other Courses

    Fullstack Flask can help you save time, money, and frustration vs. going with other courses.

    Expert Instructors

    Sumukh works at AngelList building production applications - he also taught Python at U.C. Berkeley. (and newline has tens of thousands of happy students)Who knows. Often unreliable, inexperienced teachers

    Comprehensive Scope

    This course goes beyond the frontend and teaches error handling, performance, sending emails, delayed jobs, and debugging.Teaches on backend and frontend at a superficial level


    Covers all of the details including structure, organization, tooling, and deployment.Leaves you wanting more, wondering how to build a "real" application.

    Why this course is different?
    Production Ready Features

    Fullstack Flask covers the code for the backend and the frontend, but goes way beyond into production-level details that are often ignored by other courses. Here's a few examples:

    Error Handling

    Errors happen, but they don't have to take down your app (or go unnoticed!) . In this course, we'll show you what the pros do: handle their errors using an error handling service like Sentry

    Delayed Job Queues

    You don't want to handle long-running requests in your main web server. Instead, pros setup "delayed jobs", which are worker processes that can perform long-running tasks in your app. We cover how to set these up (and deploy them!) in the course


    It would be great if our code ran perfectly the first time, but sometimes we need to debug. In the course, we'll show you how to use the debugger in Python - in your browser!

    100% Test Coverage

    Tests are a must in any pro application. The app in Fullstack Flask has 100% test coverage and we show you how to write the tests

    Use the SQLAlchemy ORM

    SQLAlchemy is an ORM what is super powerful. In the course we'll show you how to use this ORM - and it's related devtools

    Deploy the whole thing

    The app has an architecture that is more than just a web-server. With a database and delayed jobs, there are several moving pieces - and we show you how to deploy them all in this course

    Questions you might have

    Here are answers to some common questions

    Yes! Flask comes with the basic components to run a web server. Later you can import other libraries and everything you need to scale your web application to where you want to. It's easier to start with Flask because it doesn't throw at you all the components. It's just throwing you a minimal set of things, one at a time.

    The Python Developer's Survey of 2019 ran by the Python Software Foundation showed that Flask is the most popular Web Framework used by Python developers. - Yes! Flask comes with the basic components to run a web server. Later you can import other libraries and everything you need to scale your web application to where you want to. It's easier to start with Flask because it doesn't throw at you all the components. It's just throwing you a minimal set of things, one at a time.

    The sample project we will be developing throughout the course will be an online marketplace like Gumroad. Inside of the marketplace you will be able to create stores, integrate payment processors like Stripe, and much more.

    The entire application you will build throughout the course has 100% code test coverage. What that means is that the test hit every line of code, making sure it works properly.

    When joining the course, you'll be invited to our community Discord where you can chat with fellow students.

    You'll log in to your newline account and progress through the lessons. You'll also be able to download the completed application and videos.

    I teach the concepts of the course in a very simple way, so anyone with a basic understanding of Python can follow along.

    If you're unhappy with the course for any reason, just reach out to us and we'll give you a full refund. No risk involved.
