Replatforming e-commerce.
Off Magento, onto a modern Node.js backend.
A wholesale marketplace where brands sell to independent retailers. I led the team as hands-on Tech Lead and was the top contributor on every portal.

01 · The problem
The old platform was holding the product back.
The marketplace started on Magento and an agency-built frontend. When the business moved to B2B wholesale, it needed buyer groups, bundles, payouts and new payment options faster than Magento allowed, without stopping the business.
02 · What I built
A marketplace, rebuilt piece by piece.
Supplier portal
Listings, bulk CSV upload, bundles and pre-packs, orders and payouts for brands.
Admin portal
Brands, buyers, orders, payouts, reconciliation, coupons, campaigns and a CMS for the site.
New Node.js backend
A NestJS GraphQL service with queues, search and role-based access, replacing Magento.
Modern payments
Cards, Apple Pay, Google Pay, buy now pay later for businesses, and Stripe Connect payouts.
Test-driven CI/CD
Storybook components and Playwright end-to-end tests on every change.
03 · Key decisions
Raise the bar, then ship.
Phase out, don’t big-bang
Magento was replaced step by step: first a mock server so the frontends could move ahead, then a new service, then the B2B platform.
Standards the team owns
I led a team of 6, set code standards and a shared component library, and delivered products on time.
