A Shopify partner who thinks like a store owner.

Developer by training, store manager by habit. I write the code and I read the numbers, so changes that should make money actually ship.

I'm John Paul Guisijan. For more than five years I've done one thing: build and grow Shopify stores. I started as a developer, writing custom Liquid, fixing what broke, and speeding up slow themes. Over time the work grew into running the whole store.

I've managed live stores for DTC brands across wellness, pet health, beauty, kids, and lifestyle products, together serving more than 650,000 customers. That meant planning and shipping the A/B tests, handling SEO, launching offers and seasonal promos, and reporting on what actually moved.

Because I can also write the code, nothing waits in a dev queue. I treat your store as a business that has to make money, not a design exercise. If you already have traffic but too few of those visitors buy, that's exactly the problem I'm built to solve.

Have a store that should be selling more?

Tell me what's working, what isn't, and where you want the store to be. If I'm not the right fit, I'll say so and point you somewhere better.
