I’ve had the opportunity to see John’s work on advanced JavaScript projects through Upcart, and what stands out the most is his speed in approaching and solving problems. He doesn’t waste time overcomplicating things—he’s able to look at an issue, quickly understand what’s going on under the hood, and then move straight into building a solution. This makes him a great fit for situations where time is limited and results are needed fast. John’s strength lies in his ability to break down complex JavaScript logic into smaller, more manageable parts. Instead of trying to brute force fixes, he works step by step, testing along the way, which gives his solutions a solid foundation. For example, when tackling asynchronous programming challenges, he quickly identifies whether callbacks, promises, or async/await is the right approach and then implements it cleanly. This efficiency doesn’t just save time—it also reduces the risk of introducing bugs down the line. That being said, his speed doesn’t come at the cost of readability. His code is usually straightforward and easy to follow, which is especially useful when collaborating with others or passing projects along. He also has a good habit of leaving things in a state that makes future updates easier, which is something many developers overlook when they’re working quickly. In terms of debugging, John is equally fast. He has a strong sense for where problems are likely to be, and he doesn’t spend long hours chasing errors blindly. Instead, he uses a combination of testing tools, console logging, and systematic isolation of functions to zero in on the problem area. This methodical approach makes him not only quick but also reliable—fixes are thorough rather than temporary. One area where John could grow is perhaps in slowing down at times to add more documentation or explanations alongside his work. While his code is readable, a little extra context would make it even more accessible for people new to the project. But overall, this is a minor trade-off for the speed and effectiveness he brings to the table. Using Upcart with John’s contributions has been a solid experience. The app feels smoother, and it’s clear that his ability to quickly solve advanced JavaScript issues plays a role in that. He’s someone you can count on when complex tasks arise and deadlines are tight. If you’re looking for a developer who can strike a balance between speed, reliability, and clean JavaScript implementation, John is a strong choice. He’s not just fast—he’s consistent, practical, and focused on getting things working the right way.

I'm newish to Shopify and was confused about how the app worked. I ended up getting such quick and great customer service from the UpCart team. Totally a complete 180. Brandon and the team were truly so helpful!

perfect

Great app. Brandon chat support guy I got couldn't have provided me with a better service. Super polite, helpful, and most important fast and professional. Definitely recommend

Very user friendly UX and a really great product for the price

Great help with app set up

Very helpful in assisting me with the configuration of the upsells. Even sent me a loom video to help explain one bit. Thanks Brandon

Michelle helped with with an issue I had and solved my problem immediately! It was late at night but she was there in the chat to help. Thank you!!

Good app, good customer service HIghly recommend

The app has some great functionalities and the customer service was very kind in helping me fix some issues with translations

I installed UpCart mainly to offer rewards directly in the cart, and it's been super straightforward to set up. The interface is really easy to use, and I’ve been testing out the upsell and reward features. So far, I’ve already seen a few upsells come through, which is a great early sign. Shoutout to Hailey from the support team—she noticed I wasn’t getting anywhere with the AI bot and jumped in to help without me even asking. Really appreciated that kind of initiative!

Geweldige app! Conversie verhogend op verschillende vlakken. En de support is snel en accuraat!

Michelle from UpCart Drawer was brilliant! She was patient, extremely helpful, and we fixed the problem quickly. I wish I had spoken to her sooner, very happy with the experience.

Upcart is great if you want to increase your AOV. Team is very helpful and responsive. Def recommend.

It's worked really great for us so far - with some minor issues with compatibility. Recently we had an issue with the cart drawer showing up, and initially I was directly to an ai support who only re-parroted what I'd already read in the help guide and searched on chat gpt myself. However, once I asked for an escalation, I reached Patti who was able to identify a solution very quickly. Hopefully the app continues to be compatible with our store because it offers an easy way to boost sales and show offers before checkout.
