Hiring the wrong Shopify developer wastes your money, delays your launch, and can leave you with a store that is slow, broken, or impossible to manage. In this guide I walk you through exactly what to look for - technical skills, portfolio signals, communication quality, and the red flags that should make you walk away immediately.
Why Choosing the Right Developer Matters
Your Shopify store is your most important sales asset. A poorly built store loses customers at every step - slow load times, broken mobile layouts, confusing checkout flows. The developer you hire directly determines whether your store converts or costs you sales every single day.
- A slow store loses up to 7% of conversions per extra second of load time
- Poor mobile experience affects over 60% of your traffic
- Bad code is expensive to fix - often cheaper to rebuild
Quick Tip: Spend one extra hour vetting a developer before hiring. It will save you weeks of fixing problems after the project.
Must-Have Technical Skills
A qualified Shopify developer must know these technologies confidently - not just claim to know them.
Liquid - Non-Negotiable
Liquid is Shopify's templating language. Every Shopify theme is built with it. If a developer cannot explain Liquid objects, tags, and filters confidently - they are not a real Shopify developer.
- Understands objects - product, collection, customer, cart
- Uses filters correctly - image_url, money, date, upcase
- Writes clean loops and conditionals
- Knows how to use Sections and Blocks properly
Frontend Fundamentals
- HTML5 - semantic, accessible markup
- CSS3 - responsive layouts, Flexbox, Grid
- JavaScript - ES6+, async, DOM manipulation
- AJAX cart - update cart without page reload
Shopify-Specific Knowledge
- Dawn and Horizon theme architecture
- JSON templates and Sections Everywhere
- Metafields and Metaobjects
- Shopify CLI and theme development workflow
- Storefront API basics
Test Them: Ask one simple question - "How do you output a product's featured image in Liquid with lazy loading?" A real Shopify developer answers this in under 30 seconds.
How to Evaluate a Portfolio
A portfolio tells you everything - if you know what to look for. Do not just look at how the stores look. Test them.
- Visit every live store link - does it actually load? Is it still live?
- Test on mobile - resize the browser or open on your phone. Is it truly responsive?
- Check PageSpeed - run their stores through pagespeed.web.dev. Any score below 60 on mobile is a warning sign.
- Look at the details - hover states, animations, font consistency, spacing. Good developers care about the small things.
- Check the cart and checkout flow - add a product, go to cart. Does it work smoothly?
Pro Tip: If a developer shows you Figma mockups or screenshots instead of live store links - that is a red flag. Always ask for live URLs.
Experience Level to Look For
You do not always need the most senior developer - you need the right experience level for your project.
- Theme customisation or store setup - 1 to 2 years experience is sufficient. Look for clean work and good communication.
- Custom theme from scratch - 2 to 3+ years. They should have built at least 3 to 5 custom themes they can show you live.
- Figma to Shopify - Must have done this before. Ask specifically for Figma-to-live examples in their portfolio.
- Shopify Plus or complex integrations - 4+ years with proven Plus or API experience.
Communication Skills
Technical skill is only half the picture. A developer who cannot communicate clearly will cause just as many problems as one who cannot code.
- Responds to your first message within 24 hours
- Asks clarifying questions - not just says yes to everything
- Explains their process in plain language
- Provides updates without you having to chase them
- Is honest about timelines - not just tells you what you want to hear
Signal to watch: How fast and how clearly they respond to your first message is exactly how they will communicate throughout the entire project.
Their Development Process
A professional developer follows a clear process. Ask them how they work before you hire them.
- Discovery - Do they ask about your brand, audience, and goals before starting?
- Staging environment - Do they build and test on a staging store before going live?
- Revision rounds - How many are included? What happens if you need more?
- Handover - Do they walk you through the finished store and explain how to manage it?
- Post-launch support - Is there a support window after delivery?
Tools They Should Know
- Shopify CLI - For local theme development and version-controlled workflow
- Git and GitHub - For code version control and safe deployments
- Figma - For reading and implementing designs accurately
- Google PageSpeed Insights - For testing and optimising performance
- Chrome DevTools - For debugging layout and performance issues
Git for safe code
Figma to pixel perfect
PageSpeed optimised
Red Flags to Avoid
- Cannot show a single live Shopify store
- Cannot explain what Liquid is
- Says yes to everything without asking questions
- Promises a full custom store in 2 to 3 days
- No GitHub profile or code samples available
- Asks for 100% payment before starting
- Disappears for days between messages
- Portfolio is only screenshots or Figma files
- Cannot explain their revision or handover process
Rule: If something feels off in the first conversation - trust that feeling. The best developers are confident, clear, and have work to show for it.
