Migrated a client website from Magento 2 Enterprise to Shopify Plus — 2025

Owned the backend of the platform migration from self-hosted Magento Commerce (Adobe Commerce) to Laravel Product and Vendor Agregator + Shopify Plus.

Acted as technical lead on the frontend track alongside the project manager, setting architectural direction and reviewing delivery from the frontend team.

Economy on Adobe Commerce licensing, dedicated production hosting (app servers, DB, Redis, Elasticsearch, Varnish, staging) and the DevOps / security-patching overhead that came with a self-hosted Magento stack — replaced by a flat Shopify Plus subscription. Conservatively a 2.5–3× reduction in annual platform TCO.

−80% origin load

Edge-Cached Rendering for Magento 2

Built a custom module that rewrote Magento 2 response headers (Cache-Control, Surrogate-Key, Vary) so HTML pages became cacheable at the Cloudflare and Browser edge — shifting full-page caching off the origin and onto the CDN.

Implemented an internal smart cache-warming system for Magento's Full Page Cache (FPC): proactively re-heats hot pages before TTL expiry, keeping origin TTFB low and preventing cold-cache spikes during traffic bursts.
