Responsibility for architecture and solution design

Backend Technical Lead
Backend Technical Lead
  • Acted as embedded technical lead for Micromania (part of the GameStop group), owning architecture and solution design for a five-person team; also worked part-time as senior backend developer on a Tissot storefront re-platform and the LVMH account
  • Reviewed and estimated backlog tickets, wrote implementation plans, and ran requirement-discovery calls directly with clients, producing technical specs with business analysts and frontend leads
  • Designed a console-rental integration: PDP flow handing off to a third-party provider for payment data capture, with async callback-based status updates
  • Rewrote pagination logic so promotional tiles could sit between products without breaking page counts or totals
  • Delivered a premium subscription (digital product) feature spanning PDP, cart, and checkout
  • Rebuilt scheduled data-sync jobs (catalog, inventory, pricing, customer, orders) between internal ERP systems and storefronts, eliminating job collisions and manual intervention by chunking large catalog imports
  • Owned code review and the release pipeline ? Jenkins deployments through test, staging, and production ? with post-release monitoring, rollbacks, and hotfixes
  • Investigated client-reported production issues via logs to find root cause, then shipped hotfixes same-day when client testing allowed, or first thing the next morning otherwise
