About this service

Summary

I help Shopify brands boost conversions through smart, custom-built features that elevate the customer journey. From advanced product customizers to “build-your-box” flows and filter systems. I develop high-impact, conversion-driven components tailored to your store and audience. Whether you're looking to improve UX, increase AOV, or simply make your site more interactive, I turn complex ideas into seamless, high-performing Shopify experiences.

Process

1. Discovery & Briefing We start with a collaborative call or written brief to understand your goals, users, and business challenges. Whether you already have an idea or need help defining it, I’ll help shape it into something technically feasible and commercially smart.

2. Scoping & Planning Based on the brief, I define the scope of work, key features, integrations, and expected timeline. You’ll receive a clear outline of deliverables and milestones. No surprises later on.

3. UX & Wireframing (optional) If needed, I create simple wireframes to map out the structure and flow of the feature or component. This helps align on logic and user journey before visual design begins.

4. Visual Design & Prototyping Next, I design the feature/component in Figma, fully aligned with your brand. You’ll review and approve the design before development starts. For interactive experiences (like customizers), I can also build a working prototype.

5. Development & Integration I bring the design to life in your existing Shopify theme using clean Liquid, JS, and CSS. Everything is mobile-responsive, fast, and built with performance and scalability in mind. I also handle app/API integrations if required.

6. Testing & QA Before going live, I test the implementation across devices and browsers to ensure smooth UX, clean performance, and bug-free functionality. You’ll have a chance to review and sign off.

7. Launch & Support Once approved, I push the feature live (or hand over if you prefer to launch yourself). I offer post-launch support to make sure everything continues to work as intended and to make adjustments if needed.

FAQs

How long does a typical project take?
It depends on the scope, but most custom features or components take between 3–5 weeks from brief to launch. Larger builds like product customizers or interactive bundles may take 8–12 weeks. I’ll always provide a clear timeline before we start.
Do I need a full design before we start?
Nope! I can work from an existing design, collaborate with your designer, or create the design from scratch based on your brand and goals. We’ll decide together what works best for your project.
Can you work within my existing Shopify theme?
Yes, I specialize in extending and customizing existing themes. Whether it’s Dawn or a premium theme, I integrate seamlessly without breaking what’s already there.
What kind of features can you build?
If it’s possible in Shopify, I can probably build it. From product customizers and "build your box" flows to advanced filtering, upsells, or smart bundles. If it helps your customer journey or boosts conversions, I’m all in.
What do you need from me to get started?
A clear idea of what you want to build (or the problem you're solving), access to your Shopify store, and any relevant brand guidelines or assets. I’ll help you fill in the rest during the briefing stage.
