Your two core skills

The two halves of being a developer

Jiki teaches you how to code (in the most fun and effective way!) and how to build real things using the same technologies the pros use. From day one.

Learn to Code

Every core concept, with detailed video explanations, and hundreds of exercises and projects to practice on

Learn to Build

Learn the technologies pros use from day one: Databases, auth, frontends, backends and more!

Learn technologies including:

  • TypeScript
  • Python
  • Ruby
  • Next.js
  • Claude
  • Cloudflare
  • GitHub
  • Mux

Learn to Code

Master coding, the core skill we use to communicate our desires to a computer. We'll help you build rock solid coding foundations.

An animation of the Jiki app: a learner runs a space-invaders exercise, the code moves the laser cannon off the edge of the grid, they ask Jiki for help, correct the boundary from 20 to 11, and the exercise passes.

Look what you'll make

Make Games. Build Animations. Solve Puzzles.

Every one of these is built from the same handful of core concepts, and you'll have made hundreds like them by the end.

  • Space invaders
  • Tic tac toe
  • Breakout
  • Maze solver
  • Flower flipbook

…and that's just the first few weeks!

Learn to Build

Quickly learn core technologies like databases, auth, frontends, backends, and more using modern agentic coding.

Hi there! 👋 I'm Jeremy, and I've helped over millions of people level up their coding skills, all around the world.

Senior DeveloperPassionate teacherMission Driven

Coding has been at the center of my life since I was 8. It's taught me creativity, problem solving, and critical thinking. And it's allowed me to have a career that I've loved, building companies across education, medicine and artificial intelligence.

I've built Jiki because I want to share that with you. I want you to be able to access the same joy and benefits that coding has given to me. And I believe that learning to code should be fun. The software development industry is changing fast. Agentic coding is becoming the norm. I'm dedicated to taking you on that journey and making sure that whether you want a career in tech or just want to know what's going on, you can. I hope you'll come and join me!

I was brand new to coding and this course exceeded my wildest expectations and then some. In my humble opinion, it will be one of the best choices you will ever make!

Shaun

Getting into programming always felt overwhelming. I often quit before I really got started. However, the course has provided an excellent, guided path to self-sufficiency, and I now feel capable of growing and learning more in the field.

I joined the course with some Python knowledge, looking to learn front-end languages. I'd been struggling with self-paced learning, so I signed up for the structure and accountability. The teaching style — full of effective analogies — really clicked with me.

In just 10 weeks, I've learned new material and gained clarity on topics I thought I already understood. Fantastic mentors, teaching, community, and global cohort. The course has exceeded my expectations—I'd highly recommend it!

Matt

I'd recommend this to anyone trying to become a better programmer. I have done a fair bit of tutorial material online to learn programming but this course does the best job in teaching you the fundamentals. This course has given me confidence in writing code and made it fun! 😄.

Laura
LauraWas in Tutorial Hell

I had doubts that I would understand this kind of material, and yet as I look back to where I started, I have a deep appreciation for the incredible skills and knowledge I am now nurturing and growing. How I think about thinking, and about problem solving in general, has changed dramatically since undertaking this course. I can't wait to see what's next!

Honestly, I had no expectations when I stumbled upon Jiki, but it turned out to be my greatest discovery of the year! Given the cost, I didn't hesitate to join and give it a try. I had no experience whatsoever, and I'm very impressed with myself looking at what I can do! 100% recommended!

This course hasn't just taught basic structures and logic for programming, but it instills some basic tenets of the coder's mindset that will be invaluable on your journey (how to start from a blank screen, breaking big impossible challenges into the smallest solvable pieces, creating more efficient, readable, and maintainable code).

Robert

This course gives you the tools to think through the process before even writing a single line of code which makes the actual coding part easier. Having a good mental model helps with understanding what's 'under the hood'

As someone with no previous coding experience - I've been blown away with the quality of this course. I've come so far in the past weeks and reflecting on what I've achieved and how much I've learned has been phenomenal. My journey has been from a complete coding novice, to someone who is confident and excited to tackle complex logic problems in code!

Fred

From the moment I bought the course, I realized it would be different from anything I had ever experienced in terms of classes and studying. Learning while actually coding has made it pretty fun.

Getting help and encouraging messages from the community, sharing their experiences, and knowing that you're not alone made things much easier. It's such a pleasure to be part of it!

Lucas

This course has pushed me past what I thought were personal limitations, and in doing so, has increased my confidence and motivation. Know that when you get the certificate at the end of the course, it will be because you EARNED it!

The course provided me an opportunity to learn from a bonafide master. The purchasing power parity discount made it even more affordable. Thank you for making it accessible.

@abhinav
@abhinavBeginner

Before I started this course I didn't think I could do the exercises we do now. I thought I am not smart enough, that "this is not for me" and I didn't expect anything which required so much effort to be here in the fundamentals of programming. But in the end, Jeremy shows it's yet another skill that can be learnt, even in such a short period of time.

Oleksandra

I joined this course with some coding experience, but the clarity and structure made everything click like never before and the lessons are perfectly paced, building concepts step-by-step in a way that feels natural and engaging. It's a transformative learning experience that leaves you feeling motivated and excited to keep pushing your coding skills to the next level.

Vignesh

The course has been a game-changer for me.The pace is perfect: challenging yet not impossible. The exercises are very nice, and it is incredibly satisfying to see that in just a few weeks one can pass from simply moving a blob in a maze to program one that solve EVERY maze.

@m_artigiani

I have next to no coding experience yet have found this course to be so intelligently scaffolded, with concepts clearly explained and logically built one after the other, making the information accessible to learn.

Karen

The resources are fantastic but it is Jeremy's knack of breaking things down into the smallest possible steps that has really helped things click for me. I've learned an unbelievable amount in a few short weeks and I'm now solving problems with code that I would never have thought possible!

Enrolling in this programming course was one of the best decisions I've ever made. The curriculum is well-structured, covering foundational programming concepts. The team is supportive, and truly invested in helping students succeed.

@nanouss01
@nanouss01Beginner

For nearly a decade, I've repeatedly started online coding courses, but every time I run up against something that didn't make sense or a problem I just couldn't solve which stopped me in my tracks, meaning I have never completed a course, but now after years of trying, suddenly, coding feels possible.

The Big Jiki & Exercism Translatathon

Over the weekend of July 31st - August 2nd, we're translating Jiki and Exercism into as many languages as we can, together. Here's how it works and how you can help.

How to get into tech in 2026

For 30 years, code was the gatekeeper into tech. Now that LLMs write it for you, the route in has changed. Here's how to actually get into tech in 2026.

Should I still learn to code in 2026?

It's 2026 and Claude can out-code me in seconds. So why bother learning to code? Because you still need to read code well enough to catch the mistakes LLMs confidently make.
