FAQ
What kind of customizations can you do?
I specialize in a wide range of Shopify customizations, including: layout changes, adding sections, dynamic product bundles, custom filters, color swatches, cart logic, animations, metafield integrations, and more. If you have a specific idea or feature in mind – chances are, I can build it!
Can you make my Shopify store look exactly like my reference website or design file?
Yes! I can replicate the design pixel-perfectly, whether it’s a reference store, a Figma/Photoshop design, or just a screenshot. Let’s bring your vision to life.
What is the typical process for completing a Shopify project with you?
The process for completing a Shopify project with me begins with a thorough discussion of your project requirements. Once we've outlined the scope, I'll provide you with a detailed project proposal and timeline. We'll work closely together and I'll provide regular communication and progress updates.
Will my Shopify store remain online and functional during development?
Yes, I always prioritize minimizing disruptions. All customizations are done on a duplicated and unpublished theme version of your live theme. This ensures your store stays fully functional and visible to customers while I work behind the scenes.
Will I be able to edit the content and sections myself later on?
Yes! I always build with the Shopify admin in mind. You’ll be able to manage text, images, products, and even custom sections easily – no coding required. If needed, I can even provide a short walkthrough after delivery.
Can you provide an estimated project timeline based on my specific requirements?
Absolutely! I understand that each project is unique. Upon reviewing your specific requirements, I'll provide you with a customized project timeline. My goal is to deliver your project efficiently while maintaining high-quality standards.
Are there any factors that could affect the project timeline?
Project scope changes or additional feature requests can indeed impact the timeline. However, I'm committed to working closely with you to manage these changes effectively. We'll discuss any adjustments to the timeline as needed and ensure that they align with your project's goals and priorities.
How do you handle progress updates during the development process?
I believe in transparency and effective communication. Throughout the project I'll provide regular progress updates, ensuring that your project is on track. I'm always available to address any questions or concerns you may have along the way.
How do you handle the process of making my Shopify project live?
Making your Shopify project live involves final testing, client review and approval. I'll ensure a smooth transition to your live store.
Revision Policy
My revision policy includes certain rounds of revisions to ensure your satisfaction. Please provide clear and specific feedback to help me implement your requested revisions efficiently. Note that significant scope changes may impact the project timeline and cost,and we will discuss these adjustment
