E-commerce developers who have changed a store that was already trading

An online store is the one codebase where a bad deploy shows up as lost orders within the hour. Cortance matches e-commerce developers who have changed a store that was already trading, not only built one from scratch. You get a shortlist within 30 minutes of sending a brief, and a chosen engineer can start in 2 days.


What e-commerce experience looks like in practice


Take Dmitry A., a senior backend engineer on Node.js and TypeScript. He worked on the platform of a Swiss luxury watch and jewellery retailer selling across Europe and the US, built for Black Friday peaks of around 100,000 requests per second. His main task there was replacing the payment provider, whose unannounced breaking updates kept failing quietly in production. He moved checkout to Saferpay, extended and partly rewrote its immature Node.js library, and removed the old integration without interrupting orders. He also added a US sales tax service so customers saw tax before paying.


On the storefront side, Vitalii P., a senior frontend developer, built React components for Solo Stove and Loewe on Salesforce Commerce Cloud, including product pages, mini cart, checkout flow and order summary. For Solo Stove, code splitting, lazy loading and tree-shaking cut the JavaScript bundle by 40% and improved Time to Interactive by 3.2 seconds.


Hire e-commerce developers by the problem, not the platform


Our e-commerce network covers Shopify, Magento, WooCommerce, Salesforce Commerce Cloud and headless storefronts on React and Next.js. The platform narrows the search, but the problem decides who we send:


  1. Checkout or payment provider change. A backend engineer who has moved a live store between gateways and kept orders flowing during the switch, as Dmitry A. did.
  2. Subscription commerce. An engineer who has built recurring orders, stored payment methods and pauses or cancellations mid-cycle. Dmitry A. implemented the US subscription product for illy's coffee business, where tax and shipping rules also change by state.
  3. A slow storefront. A frontend engineer who measures bundle size and Time to Interactive before changing components, as on the Solo Stove build.
  4. A store that needs steady care. An engineer comfortable making small, safe changes in code other people wrote, on a site that is already trading.


Moving to a new platform is its own job, with URLs, order history and inventory cutover to plan; the replatforming section below covers what to ask.


AI coding tools help most on the repetitive parts of store work, such as regression tests for checkout paths and scripts for product-data migrations. Payment, tax and pricing logic still gets a human review line by line, because a model does not know which discount rule a merchant configured last quarter.


How engagements work and what they cost


Senior e-commerce engineers on Cortance typically work at $26-45 an hour, depending on platform and seniority. You can start with one engineer on a checkout redesign, add a lead for a replatforming, or build a small team. Tell us the platform, the problem and the timezone overlap you need.


When you may not need an e-commerce specialist


A standard Shopify theme with a few apps is often better served by a generalist frontend developer or by the platform's own partners. A specialist earns the rate when money flows through custom code: payments, subscriptions, ERP sync, or traffic that spikes.

What a store engineer touches that a website engineer does not

A marketing site can be wrong for a day and nobody notices. A store cannot. Price, tax, stock and payment state all have to agree at the moment a customer clicks pay, and each lives in a different system: the catalogue, a tax service, the warehouse, the gateway. Most e-commerce incidents are disagreements between two of those systems, not bugs in one.


That is why the cost of a hire is rarely the hourly rate alone. The drivers are the platform (a hosted one like Shopify limits what custom code can do, a self-hosted one like Magento does not), the number of external systems the store talks to, how much traffic spikes, and whether the engineer is inheriting someone else's code. A theme change on a hosted platform and a payment provider migration on a self-hosted one are different jobs, even though both are called e-commerce development.

Replatforming without losing orders or rankings

Moving a live store to a new platform goes wrong in predictable places. A good brief for a replatforming names them up front:


URLs and redirects. Every product and category URL that ranks needs a mapped redirect, or organic traffic drops on launch day.

Order history and customers. Past orders, accounts and stored payment tokens have to move, or be rebuilt with the customer's consent to re-enter cards.

Parallel running. Inventory and orders should stay in one source of truth during the cutover, so the two stores never sell the same last unit.


Engineers who have run a migration before ask about these in the first call. If yours does not, that is worth noticing.
