Shaheen E-Commerce.

Solo-rescued a live multi-vendor marketplace — 300+ master commits (100% code ownership), 100+ PRs merged, 55+ issues closed.

Delivered end-to-end across the full stack — Livewire 3 Volt components, Filament 4 admin panel, Blade templates, Alpine.js, and Tailwind v4:

• Double VAT Leak: Identified and purged a redundant 14% VAT overcharge in ShippingRateService::vatFor() that was silently bleeding client revenue.
• Checkout Pipeline: Re-architected a broken P0 checkout flow into strict DB transactions, unblocking the revenue pipeline. (Paymob online-payment gateway integrated behind a feature flag, pending merchant onboarding.)
• Ops Rescue & Drift Checking: Resolved a critical HTTP 500 deploy outage caused by 13,427 divergent server-edited lines. Deployed a 6-workflow CI/CD pipeline and a nightly drift checker.
• Security: Eliminated a P0 CSRF 419 error on logouts via event-delegation token refresh, dropping failure rates from 3 retries to first-click success.
• Enterprise SEO: 10 JSON-LD schemas, dynamic meta titles/descriptions, image sitemaps, multi-language hreflang routing
• Multi-region shipping rate matrix (4 size tiers, vendor-split) and intelligent tire-size cross-reference engine (2 up / 2 down)
• Google OAuth via Socialite, email verification via Resend with branded dark-mode templates, saved delivery addresses, avatar crop/zoom/rotate
