BigCommerce Developers
for any job

A BigCommerce developer is an e-commerce specialist who builds, customizes, and maintains online stores on the BigCommerce platform, handling theme development, app integrations, Stencil framework coding, and storefront optimization. Hiring a skilled BigCommerce developer means partnering with a professional who can translate your retail vision into a fast, conversion-ready storefront that scales with your business.

What a BigCommerce developer delivers

A freelance BigCommerce developer takes ownership of the technical layer of your online store, from the initial theme build to ongoing performance work. Their output directly affects load speed, checkout completion rates, search visibility, and the cost of running your catalog. Strong BigCommerce specialists understand both the front-end shopper experience and the back-end logic that powers product data, pricing rules, and order management.

Commercially, a well-built BigCommerce store reduces cart abandonment, supports multi-channel selling across marketplaces and social commerce, and gives merchants the flexibility to launch promotions, B2B price lists, and headless storefronts without rebuilding from scratch.

Core services and deliverables

BigCommerce experts handle a wide range of technical and creative tasks across the store lifecycle. Typical deliverables include:

Tools and technologies BigCommerce developers use

Competent BigCommerce developers work with a defined toolkit. Expect familiarity with the Stencil CLI, Handlebars templating, SCSS, JavaScript and TypeScript, Git, and Node.js. For headless builds, they should know React, Next.js, and the BigCommerce Storefront and Catalog APIs. Adjacent skills include Shopify development, Magento and WooCommerce migration, Klaviyo email flows, Google Tag Manager, GA4, and conversion rate optimization.

Industries and use cases

BigCommerce is widely used by mid-market retailers, B2B wholesalers, manufacturers selling direct, fashion and apparel brands, health and supplement merchants, sporting goods sellers, and home goods stores. Freelance BigCommerce developers also support SaaS companies selling physical add-ons, subscription box businesses, and multi-region retailers running localized storefronts. The platform's strength in B2B commerce makes it especially common for companies with complex pricing, customer-specific catalogs, or large SKU counts.

How to evaluate BigCommerce developer candidates

Strong candidates show a portfolio of live BigCommerce stores, not just mockups. Look for evidence of custom Stencil themes, API integrations, and measurable improvements like faster page loads or higher conversion rates. Verify their grasp of the platform's specific quirks rather than generic e-commerce experience.

What are the steps to hiring a freelance BigCommerce developer?

Hiring the right BigCommerce developer comes down to writing a clear brief, reading proposals carefully, and verifying past work on the platform. The process below helps you move from concept to awarded project with confidence, whether you need a new theme, a migration, or a headless build.

Step 1: Post your project on Freelancer.com

Your project post is the single biggest determinant of bid quality. A clear, specific brief filters out generic e-commerce developers and attracts BigCommerce specialists whose skills genuinely match. Head to the post project page , where you fill in the brief, scope, timeline, and budget before publishing the project for freelancers to bid on.

Step 2: Review bids from freelancers

Bids are short proposals, not just price quotes. They reveal how each developer interprets your brief, what approach they propose, and whether their timeline is realistic. Read carefully and shortlist candidates whose understanding of BigCommerce-specific challenges matches your scope.

Step 3: Evaluate freelancers and award the project

The final decision combines proposal quality with profile evidence. Weigh consistency across past BigCommerce work rather than a single impressive example, and prioritize developers with documented platform experience and reliable client feedback.
