About this gig
Want to add something to your store, or change how part of it looks or works?
I'm a Shopify developer with 5 years of hands-on experience in Liquid, HTML, CSS, and JavaScript. I write code that holds up when you update your theme and doesn't need revisiting six months later.
This gig is for changes and additions. If something is broken, my Bug Fix gig is the right place.
What I work on:
- Product page layouts: tabs, accordions, custom content sections, image galleries
- Cart and drawer work: custom styling, upsell blocks, behaviour changes
- Banners, announcement bars, promotional sections
- Custom JavaScript features: sliders, sticky elements, interactive components
- Speed and performance improvements
- Mobile layout fixes
Pick the package that fits:
- One Change: one specific element adjusted or added in one area
- Feature Build: a new feature, or one area significantly reworked
- Store Upgrade: a complex build or work across several areas
Send me a message before ordering. Tell me what you need and I will confirm the right package within the hour, or put together a custom offer if your project sits outside these tiers.

FAQ
Not sure which package you need?
Message me first. Tell me what you are trying to achieve and I will point you to the right package, or put together a custom offer if needed. I reply within the hour on working days.
Do you work on any Shopify theme?
Yes I work with Horizon, Dawn, Debut, and most popular premium themes from the official Shopify theme store. If you're unsure, just share your theme name and I'll confirm before we start.
What do you need from me to get started?
Store access (collaborator invite is best), a clear description of the issue or feature, and any design reference you have if necessary. The more detail you give me, the faster I can turn it around.
How is this different from your Bug Fix gig?
This gig covers adding and changing things. New features, layout work, custom elements. The Bug Fix gig is for when something stopped working or broke. Not sure which fits? Message me and I will sort it out.
