Businesses hire e-commerce developers to build, customize, and maintain the technical systems behind online stores. The right developer can help create storefronts, configure payments and checkout, connect business systems, and address performance or technical issues as an e-commerce operation grows.
What does an e-commerce developer do?
An e-commerce developer specializes in building and maintaining online stores and the systems that support them. They may work with platforms such as Shopify, WooCommerce, and Adobe Commerce (Magento), or develop custom e-commerce applications. Many specialize in a particular platform or technology stack based on the needs of the store.
Key responsibilities for e-commerce developers include:
- Designing and developing responsive storefronts for desktop and mobile shoppers
- Integrating payment gateways, shipping services, and third-party apps
- Building and customizing themes, landing pages, product pages, and checkout experiences
- Implementing authentication, data protection, and other appropriate security measures
- Optimizing site speed and Core Web Vitals
- Connecting inventory, order management, CRM, ERP, and other business systems
- Testing, troubleshooting, updating, and maintaining e-commerce functionality

Step 2: Evaluate candidates
Review candidates for e-commerce development experience that matches your platform and project.
- Review live stores or portfolio projects built on your platform
- Look for projects with functionality and integrations similar to yours
- Confirm hands-on experience with payment gateways and third-party app integrations
- Check experience with responsive design, site performance, and checkout functionality
- Review code samples or repositories when relevant and available
- Consider client feedback, Job Success Score, and relevant work history
Uma can run instant video interviews and return shortlists of candidates with side-by-side comparisons, so you can narrow your options faster.
Step 3: Interview top choices
Interviews reveal how a developer solves problems and communicates about your store.
- Ask how they identify and address technical friction in the checkout process
- Discuss their experience integrating payment gateways such as Stripe or PayPal
- Ask how they approach payment security and applicable PCI DSS requirements
- Have them walk through a past platform migration and show how they preserved SEO and data
- Discuss how they improve page performance on product-heavy stores
- Ask how they test checkout, payments, shipping, and other critical store functionality
- Adapt these e-commerce developer interview questions to your project
Schedule and conduct interviews within Upwork Messages, and Uma provides an instant transcript and summary after each conversation so you can compare candidates.
Step 4: Agree on scope and begin work
Set clear scope before work starts so both sides know what success looks like.
- Set milestones for stages such as design, development, integration, testing, and launch
- Define acceptance criteria for storefront functionality, checkout, payments, integrations, and performance
- Confirm access to your e-commerce platform, repositories, payment sandbox, and other required systems
- Agree on source-code ownership, documentation, and handoff requirements
- Define responsibilities for migration, deployment, backups, and rollback when applicable
- Set expectations for post-launch support, maintenance, and bug fixes
- Choose fixed-price milestones for defined projects or an hourly contract for ongoing work
Use messaging and the contract workroom to communicate and manage the project, backed by identity verification, payment protection, hourly tracking, and project funds for security. Uma can also help you track milestones and next steps as work begins.
