Freelance frontend · Remote
E-commerce checkout developer
I build the shopper-facing side of online stores: product pages, cart, address, payment screens, and the steps through to pay. Hourly freelance, English and Portuguese, remote worldwide.
What this work actually is
Checkout is a frontend problem as much as a payments problem. Someone has to implement the screens, the states (empty cart, invalid address, failed payment), and the connection to whatever API or payment provider you already use. That is the work I take on.
Typical scope includes storefront pages, a cart that behaves on mobile, a multi-step or one-page checkout UI, payment-method presentation, and confirmation. I work against your existing backend or commerce platform rather than inventing a new stack unless you ask for that.
Worten: frontend on checkout, not sales
Before freelancing I have been a frontend developer at Worten Portugal since 2018 (Bee Engineering, LOGOSCON, then in-house). I implemented the Vue.js interface shoppers used from cart through payment, integrated with existing checkout APIs, in production at real traffic. I was not hired to improve sales, own the backend, or run conversion tests.
What that experience is useful for: shipping a checkout UI that has to survive real traffic, real payment methods, and a live store. What it is not: a promise that your conversion rate will go up. Revenue depends on offer, traffic, shipping, and operations — not only on the frontend.
The public write-up of that UI work is here: National Retail Checkout.
Who this is for
- Store owners who need a checkout or storefront interface built or rebuilt, and want a developer who has shipped one in production.
- Startups adding a purchase flow to an existing site, with APIs or a platform already chosen.
- Teams that need remote frontend help, not an agency playbook about “optimising conversion.”
How a project runs
Free 30-minute discovery call. We look at the current flow, the stack, and what “done” means. You get an hour estimate at €60/hour before I start — a landing page is often 15–25 hours (€900–1,500); a custom site 40–70 hours (€2,400–4,200). A deposit starts the work; the rest is billed as it ships. Weekly updates while I build. Launch with you, then optional hourly or retainer support.
A landing page is usually weeks 1–2. A custom site is often 3–5 weeks. Checkout frontend is usually longer because of payment states, edge cases, and integration — the estimate on the call is the honest number for your case.
What I will not claim
I will not sell this as “I increased sales at Worten” or “I will cut your abandoned carts.” I will implement a clear, maintainable checkout frontend and tell you what is in scope and what is not. If you need a CRO specialist or a media buyer, that is a different hire.
FAQ
- Was your Worten role a sales or conversion job?
- No. At Worten I have been a frontend engineer since 2018 (including consultant years). Vue.js checkout UI in production — not CRO, marketing, sales, or a backend role. I do not claim that work increased Worten's sales.
- What kind of checkout work do you take on as a freelancer?
- Frontend for storefronts and purchase flows: cart, address, payment-method screens, and the steps through to pay, connected to the APIs and payment providers you already use. Scope is agreed in hours on a free discovery call.
- Do you guarantee more sales or fewer abandoned carts?
- No. I implement a clear, production-ready checkout interface. Revenue depends on traffic, offer, shipping, payments, and many things outside the frontend. I will be honest about that on the call.
- How do you charge for checkout work?
- Hourly, at the rate listed on this site. You get an hour estimate before we start. A typical checkout frontend is longer than a landing page; timelines depend on the current stack and integrations.
