Working with Erick was an absolute pleasure from start to finish. He built a completely custom bundle builder for our site — functionality that didn't exist before — and the final product exceeded our expectations. The attention to detail, technical skill, and ability to bring our vision to life from scratch is truly impressive. Beyond the development work itself, Erick's customer service was exceptional. He was communicative, responsive, and genuinely invested in getting it right. When we transitioned to a new theme, he went above and beyond to migrate the bundle builder seamlessly — no small task — and made the whole process stress-free for our team. If you're looking for a developer who can tackle complex, custom functionality and actually deliver, Erick is your person. We couldn't be happier with the results and would work with him again without hesitation.

Erick was great to work with! Not only did he solve all my issues, he was also incredibly responsive and sent several updates throughout. Never have I worked with a developer as knowledgeable and timely. Absolutely recommend and looking forward to working with him again!

Erick and I have worked together over the past few months to improve the functionality and presentation of our Shopify store. Without Erick's guidance and site improvements, we would not have the functioning store I expected when the web design company set it up.

Erick has done more work in general than any other developer because he gets it done without pushback, does what he says within a timely manner, and notices 911 errors when they happen and will address them accordingly to ensure we are up and running. Nice dude, good at his job. Definitely will continue to have him on our team moving forward.

Erick did a great job updating my Shopify theme to the latest version. He was thorough in verifying nothing broke post-update, communicated clearly throughout the entire process, and kept me informed every step of the way. No surprises, no issues. Exactly what you want from a developer. Highly recommend and will definitely work with him again.
