E-commerce Tech Lead

Stood up the e-commerce engineering function from scratch to a cross-functional team of four (Team Lead, Frontend, Backend, UX Research), by owning the full hiring cycle from role definition and sourcing through to onboarding
Improved mobile performance on a flagship Salla storefront, measured by Lighthouse 36 to 68, CLS down 93% (0.85 to 0.06), TBT down 85% (1,170ms to 180ms) and LCP 16s to 6s, by eliminating render-blocking assets, reserving layout space and deferring third-party scripts
Migrated an acquired competitor storefront onto an in-house custom theme in 2 days with zero downtime to live trading, by running the technical due diligence up front and rebuilding rather than adapting the template
Traced flat sales against doubled ad spend to a paid-channel efficiency gap rather than site performance, evidenced by reconciling 6 data sources (store reports, GA4, ad platforms, Clarity, lab and field Core Web Vitals); the resulting bilingual report and funnel, cart and checkout dashboards were adopted by leadership
