Shopify E-Commerce Developer | Shopify Expert | Liquid
Shopify developer specializing in Liquid, front-end integration, custom Shopify theme creation, and Shopify app development. I work on e-commerce projects where the priority is simple:
- Obtain a clean store
- Fast and fluid
- Easy to maintain
- Aligned with your business strategy
I have worked on redesigning existing stores, creating custom themes, improving the checkout, setting up acquisition funnels, integrating APIs, and developing internal applications for product, logistics, or marketing management automation.
I offer turnkey support, from scoping to deployment.
The goal is to provide you with a high-performing Shopify store, clean Liquid code, optimized front-end, a simple-to-evolve architecture, and available support for as long as necessary to ensure everything works as expected.
I use Shopify, Liquid, Hydrogen, React.js, Node.js, Tailwind, CSS, SEO best practices, and clean tracking.
Each delivery includes documentation, versioning, and a clear environment for your team.
If you want to move forward quickly, let's chat via video call. I usually respond within the hour and can offer a free initial scoping to validate the scope and deadlines.
