FAQ
Do you work with Shopify Plus?
Yes, I have 6+ years of specific experience with Shopify Plus, including checkout extensibility and headless architecture (Hydrogen/Remix).
Can you work with a theme I already have?
Absolutely. I can also recommend a premium theme if you'd prefer to start from a solid foundation instead.
What do you need from me to get started?
Collaborator access to your Shopify store, any brand guidelines you have (colors/fonts), and a clear idea of which pages or features you need.
Do you offer support after delivery?
Yes, the Premium package includes 2 weeks of post-launch support. For other packages, additional support can be quoted separately.
How does payment work for larger projects?
For Standard and Premium packages, I use Fiverr's milestone system — you pay in stages as each phase is delivered (setup, build, integrations, testing) rather than all upfront. You'll always know exactly what's been completed before the next payment.
