Five weeks ago, I started at a Shopify agency — now I’m leading a full-store redesign and managing two developers.

Garrett W.

Shopify Developer

I landed a 50-hour/month agency retainer and also earn an extra $400 every month in passive income from a new Shopify Plus store I recently built.

Nick P.

Shopify Developer

I started the year with many projects in queue and looking forward to hitting $20K per month.

Remo T.

Shopify Developer

Pipeline is wild right now—I had six discovery calls in one day. The training materials have been super helpful.

Greg R.

Shopify Developer

I got into StoreTasker, and now I’m getting access to premium Shopify clients with rates starting at $75/hour.

Oliver H.

Shopify Developer

I've been steadily raising my pay rate and it will be up to $60/h next month.

I had a client who wanted to include a search bar in the collection filters to help users narrow down the long list of options. My initial thought was "I'm going to need to hire someone to complete this.” Proud to say that after (almost) completing this course, I was able to complete this task!

This alone has made the training worth it for me because about 2 weeks ago I would have never even attempted.

Also, I think this course is an excellent resource for any agencies that are hiring new devs. The last agency I worked at wasted a lot of time with onboarding. If we had access to this, I would have made this course mandatory for all new hires!

Agency Owner, Patane

I've started the training, although I haven't had much time to dedicate to it yet, but it's been great so far. The value is awesome, especially the workflow with the dev environment. I've already started using it with my clients!

Ignacio Velázquez

Shopify Developer

It's been a transformative learning journey for me.

When I started the training, my JavaScript skills were pretty basic— could use querySelector to show or hide elements, but that was about the extent of my capabilities.

I decided to take the course because I lost my main JavaScript developer, and I realized I needed to both hire someone new and also skill up myself. This course was the first time I genuinely felt like I was beginning to understand JavaScript, especially in the context of Shopify.

I now understand core principles and feel much more confident approaching projects that involve it. The practical lessons tailored to the Dawn ecosystem and Shopify workflows were incredibly helpful.

Thank you so much for creating this resource—it's had a big impact on my skills and confidence.

Agency Owner, Longshore

Wish I knew about the debugging strategies and breakpoints earlier. Would have helped me a ton in my job while debugging our own site.

Thanks, learned a lot here!

Manuel Kao

Shopify Developer

Hey Jan, just wanted to say....thank you for this amazing course! Because of it I was hired a few weeks ago at an agency after almost a year of struggling to get a FrontEnd React Gig, they loved the projects I had done from this.

Funny enough, this company mostly uses WordPress (I'm quite enjoying it actually) but want to branch out into Shopify which is one of the reasons they brought me on.

Matthew Lee

Shopify Developer

Went trough the training as one of the first users. It's awesome! :-)

Mostafa Shreif Selmy

Shopify Developer

Super excited, Jan. just started chapter 9, and l've been crossing fingers for the API chapter as l've made progress. Absolutely loving the course.
