Shopify development services
for better design, performance
and conversion rate.

Yoon Dev Studio is built on the belief that good Shopify development is equal parts relationship, design, performance, and results. We work with a small number of clients and care about their brands just as much as they do.

Hi there, I’m Yoon,
the person behind Yoon Dev Studio,
and your next Shopify expert.

I work directly and closely with a small number of clients to help shape their Shopify stores. If you care about good design, performance, results, and a genuine collaboration with a Shopify expert that will truly care about your brand — I think we'd work well together.
"Yoon was an absolute pleasure to work with. As a brand that proritises design at every touch point, it was integral to work with a web developer who understood design principles. Yoon not only had an amazing sense of design, but also implemented updates to our website to ensure the SEO was well considered & improved our overall user-interface for our customers. He was skilled in understanding Shopify as we are an ecommerce site and he possesses strong knowledge of web development & coding - nothing felt impossible for Yoon to achieve. Additionally, he had such a friendly attitude and was very trusting to work with. I have every intention on working with Yoon again for any updates, fixes and improvements to my website. Highly recommend his services."

Why work with me?

01 Efficient Process
Direct access, no agency layers
You work directly with me — no account managers, no middlemen, no endless meetings. Communication is fast, decisions happen quickly, and I'm just an email away when you need me.
02 Honest Communication
No surprises, no sales pressure
I'm upfront about what's possible, what it costs, and how long it takes. One flat monthly rate, no hidden fees, no pushy upsells. Just straightforward collaboration.
03 Strategy Before Code
Solutions that fit your actual needs
I don't jump straight into tasks. I take time to understand your store, your goals, and what's actually holding you back — so every task I work on moves the needle, not just the to-do list.
04Flexible Timeline
Start when you're ready, work at your pace
Start when you're ready, pause when you need to No lock-in, no minimum commitment. Start immediately, pause if things slow down, or cancel anytime. Your retainer works around your business, not the other way around.

"Have worked with Yoon over a long period now for our ecommerce website and he has always been super efficient with his work.Everything always comes back within the designated timeframe. He is the best dev that I have worked with hands done in terms of his technical ability and the end results of his projects. His attention to detail is fantastic and I have never had any issues post launch on anything he’s worked on for our site. Highly recommend."

"Honestly, I've never had a good experience working with web developers until I met Yoon Hou. I've now worked with him on 5 Shopify websites (including a tedious migration from woocommerce) and every time he not only delivers outstanding work in a timely manner, he goes over and beyond to get things done. He's a problem solver, dependable, and has an eye for detail. I really enjoy working with him and will continue to do so!"

"I've collaborated with Yoon on three website projects for my company, and he excelled in all three. Yoon effectively translates and executes our vision, addressing briefs and pain points with clarity. He proactively raises concerns and solves problems independently. His ability to provide mockups and create designs aligning with our vision is commendable. I look forward to continuing our collaboration on future projects."
