Ecommerce website development — custom stores and international e-commerce

Who I build for

A freelance alternative to ecommerce agencies

You are probably evaluating several ecommerce website development companies for your next store. Before you commit to a large agency quote, consider what an experienced freelancer can deliver — direct communication, no 20–30% margin on project managers, and decisions made in hours rather than weeks.

I build ecommerce sites for three types of client:

  • Small and mid-size businesses (D2C) launching or redesigning — €2,000 to €12,000 range
  • B2B shops with wholesaler pricing, installer accounts, multi-currency, technical catalogs
  • Enterprise teams looking for a skilled frontend contractor on Salesforce Commerce Cloud, Shopify Plus, or similar platforms

My portfolio includes projects from a single-owner D2C brand (SHE swimwear, 6 languages) to an international wholesaler (Montersi, thousands of SKUs) and a public enterprise ecommerce (Horze.de on Salesforce Commerce Cloud, nearly 4 years of frontend work).

Platforms

Ecommerce platforms I work with

I pick the platform that fits your business — not the other way around. Here is what I can deliver and the trade-offs for each option.

WooCommerce (WordPress)

Best for content-heavy stores where the owner also writes blog content. Low entry cost, huge plugin ecosystem. I build custom themes and resolve the common performance issues that plague default WooCommerce installs.

PrestaShop

Strong fit for B2B catalogs with technical attributes and complex pricing (installer vs end-customer groups). I've built custom modules, migrated from older platforms, and handled large SKU counts.

Salesforce Commerce Cloud

Enterprise-grade platform for large brands. I've worked on Horze.de at Rocksoft for nearly 4 years — Page Designer components, campaign landings, checkout modules, seasonal promotions.

Headless ecommerce (Astro + API)

A modern approach for businesses that want the fastest storefront possible. Astro frontend + any commerce API (Shopify, Medusa, BigCommerce). Better Core Web Vitals, better SEO, more flexibility — at the cost of two systems to maintain.

Custom (Laravel, Phalcon)

When off-the-shelf platforms don't fit — unusual business models, niche marketplaces, D2C brands with complex configurators. I've built custom stores on Phalcon (SHE swimwear, Pilgini) and can now recommend Laravel + Filament for new projects.

Shopify (frontend)

For established stores on Shopify or Shopify Plus, I work as a frontend contractor — custom Liquid themes, app integrations, performance optimization. Not my recommended starting point for new stores, but strong choice for many existing ones.

Services

What I deliver on an ecommerce project

  • Custom frontend — pixel-perfect implementation from Figma/Adobe XD designs, or I\'ll work with your designer. Responsive, accessible, SEO-ready.
  • Catalog architecture — product types, variants, attributes, category trees that scale to thousands of SKUs.
  • Payment and shipping integrations — Stripe, PayPal, Przelewy24, Adyen; shipping providers via carrier APIs.
  • Multilingual and multi-currency — real-world experience with 6-language stores (SHE swimwear: PL, EN, IT, DE, FR, ES) and multi-currency (EUR, PLN, USD).
  • Admin panel customization — editorial workflows tailored to the team, not the generic CMS.
  • Platform migration — moving from Magento, older PrestaShop versions, bespoke platforms to modern stacks. Data integrity, URL preservation, 301 redirects planned.
  • Performance optimization — image pipelines, lazy loading, critical CSS, code splitting. Target: sub-2-second LCP on mobile for product pages.
  • SEO foundations — structured data (Product, Offer, AggregateRating), canonical handling, hreflang for international stores, clean URL structure.

How we work

Ecommerce project process

From first call to a live store — a clear five-step flow with weekly checkpoints.

Discovery call

We talk about the business, your catalog, the target audience, existing systems, and the budget. 30–60 minutes, free. I pick a platform recommendation based on actual constraints.

Quote and scope

I send a detailed scope document with pricing, timeline, and platform justification. You approve before any code is written.

Design and build

Weekly iterations on a staging environment. You see progress every week, not every month. Feedback is incorporated as we go — no "big reveal" at the end.

Testing and launch

Payment sandbox testing, cross-browser QA, mobile QA, performance budgets, SEO audit. Go-live with DNS and SSL handled.

Post-launch support

30 days of free fixes for anything that slipped through. Optional ongoing support contract for updates, monitoring, and new feature work.

FAQ

Frequently asked questions

Do you work with clients outside of Poland?

Yes — most of my ecommerce work has been international. Horze.de (Germany), SHE swimwear (six European markets), and Salesforce Commerce Cloud projects for global brands. I communicate in English and Polish, quote in EUR, and invoice from my Polish business entity (EU B2B VAT OSS).

Which ecommerce platform should I choose?

It depends on your catalog size, team skills, and growth plan. For small D2C brands launching now, Shopify or a light custom build. For content-heavy stores, WooCommerce. For B2B with complex pricing and catalog, PrestaShop or a custom Laravel build. For maximum speed and SEO, headless with Astro. Book a discovery call and I'll recommend based on your actual constraints.

How long does it take to build a custom ecommerce site?

A simple MVP with 20–100 products takes 4–6 weeks. A custom store with multilingual and integrations: 2–4 months. A headless architecture with full ERP integration: 3–6 months. The biggest time factor is usually content and product data preparation on the client side.

Can you migrate my store from another platform?

Yes — I've migrated stores from older PrestaShop versions, bespoke platforms, and classic WordPress setups. The hard parts are preserving URLs (301 redirects), product data integrity (especially variants and attributes), and customer accounts. I plan migrations with a dry-run on staging before the production cutover.

Do you offer ongoing support after launch?

Yes — 30 days of free fixes after launch are standard. Beyond that, I offer ongoing support contracts: either a fixed monthly retainer for small updates, or hourly for ad-hoc work. Most of my ecommerce clients keep a retainer for 3–6 months after launch for tuning and feature additions.

What are your payment terms?

50% after scope approval, 50% after launch for projects up to €6,000. For larger projects: milestone-based payments (25% / 25% / 25% / 25% at defined checkpoints). I work B2B under a standard contract — VAT invoice issued from SPOKO SPACE (Polish entity), EU VAT OSS compliant.

Is it worth hiring a freelancer instead of an ecommerce agency?

It depends on your project size. For budgets under €15,000, a freelancer is usually better: direct communication, faster decisions, 30–50% lower cost. For very large projects (€50,000+, multiple specialties, strict deadlines), an agency's bench depth is worth the markup. Many ecommerce agencies also outsource their development work to freelancers — ask explicitly who will write your code.
