A Hyvä storefront where checkout had stopped working
Hyvä storefront · European retailer
Two custom modules were writing into the same merged JavaScript and CSS bundles. Pages rendered inconsistently and the purchase flow failed depending on how a customer had navigated there — a fault that doesn't reproduce reliably, which is why it had gone undiagnosed.
I traced the collision through Hyvä's asset merge, re-registered the conflicting bundles, and rebuilt the affected checkout and CMS layout blocks.
Full purchase-flow reliability restored on a live store, with ongoing Hyvä theme work afterwards.
Product data being typed in by hand, three times over
Magento 2 · Akeneo PIM · ERP
Catalogue, stock and pricing lived separately in Akeneo, the ERP and Magento, kept in step manually — slow, and wrong often enough to cost orders.
I architected and built end-to-end synchronisation across all three, covering product data, inventory, pricing and order workflows, with REST and GraphQL endpoints and secure data handling throughout.
Staff stopped re-entering product data by hand across three systems. The APIs I built are still running in production today.
Upgrades nobody wanted to run
Platform upgrades · multiple merchants
Merchants were postponing Magento version upgrades because earlier attempts had caused outages, which left their stores sitting on unpatched releases.
I ran full-lifecycle upgrades with staged validation, resolved third-party integration breakage, and put pre-deployment QA in place across the team.
Upgrades completed with limited downtime and a marked drop in post-launch defects.
