Remote Nation

Jonathan is not only a highly competent Shopify expert, he is also a really nice partner to work with on a project. He is patient, thoughtful and professional. I always felt he cared about us and did his best to help us achieve our vision. This is our first Shopify experience. Jonathan took the time to answer questions and conduct tutorial sessions with my team. He's a very good teacher. I'd highly recommend his services and we plan to stay in contact with him to call on him for future help as we build our Shopify business. Thanks, Jonathan!

Nectar & Green

Jonathan is really wonderful to work with. He makes things simple and clear, and is fast, kind and communicative throughout the development process. He's knowledgeable on even the most complicated Shopify app integrations, and has an eye for detail and aesthetic. Highly recommend!

Duluth Pack

Jonathan is fantastic. He accomplished what many said was impossible, and he was a crucial part to the success of our business. I look forward to using Jonathan and his company in the future, as his reliability, fairness, accuracy and communication are exactly the qualities we want in a developer. Thank you Jonathan!

Emerson & Church

I'm a small business owner wearing many hats. The most ill-fitting one is dealing with technology. When we needed to revamp our website, I wanted a willing and knowledgeable mentor and I hit the jackpot on that score with Jonathan. He knows Shopify inside and out, had incredible patience with my endless questions, and was always respectful of my limited budget. I'm so happy with our new website and I'm very grateful to Jonathan because it would NOT have been possible without him. Highly recommend!

Mexicali Blues

Super helpful, able to talk about the project using non-technical jargon. Prompt work was completed on time. Would recommend anytime!


Jonathan is always available for us, providing quick turn around and high-quality work. He continues to impress us with his ability to problem solve creatively within the bounds of Shopify's restrictions. He understands our needs as a growing brand and is always willing to experiment with us and bring our ideas to life. In addition to his skill set as a developer, Jonathan is also just an absolute pleasure to work with. Cannot recommend him enough!


We have worked with JAS for a couple years now and have nothing but great things to say. The best partner we could ask for.

Super Speciosa

JAS was very professional and responsive to our needs. Exceeded expectations and project was completed exactly as planned.

Shared Nation

Jonathan Schwartz has been so great that we don't even consider him a consultant, we consider him a member of our internal team. He's a true team player (willing to roll up his sleeve and help us with whatever we need). In addition, he's a top-notch developer.

Working with Jonathan has been AWESOME!! He was recommended to me by a friend and I will be sure to recommend him to anyone else looking for help with their website! He has been able to accommodate all of my needs and has really gone the extra mile in making sure the formatting for my site is all perfect and everything looks the way I envisioned. I can't say enough great things and highly recommend utilizing his services!

Disruptor Beam

We loved working with Jonathan. We had a very complex and strange task, integrating Shopify into a video game. Jonathan was completely up to it, and a total professional. It was great working with him and hope to again in future projects.

Jonathan was extremely knowledgable and easy to work with. His understanding of Shopify and Chargify - and his willingness to research any new issues - made the project run very smoothly. I would highly recommend him.
