   Zameel · Business Solutions Suite — zameel.co

   • Co-founded and shipped a production multi-tenant SaaS platform that lets Gulf merchants take and fulfil orders directly over WhatsApp; now serving 500+ active merchant accounts and processing 25,000+ orders per month
   • Architected the Node.js/Express backend on MySQL 8 and Sequelize with a Redis caching layer; schema, indexing, and caching work cut hot-path response times from ~1,150ms to ~200ms and halved external AI API spend
   • Built the LLM-powered order-parsing engine (Gemini, DeepSeek, Claude) that extracts structured orders from mixed Arabic/English messages at ~87% accuracy in production
   • Led the Tap Payments to Stripe migration end to end — checkout sessions, webhook validation, subscription billing — with zero downtime and a measurable lift in completed transactions
   • Shipped two further products on the same backend: Zameel Forms, an Arabic-first WhatsApp-native form builder, and the full admin panel covering platform settings, job postings, and applicant tracking
   • Containerized every service with Docker Compose and owned production deployment on AWS EC2 behind Nginx, standardizing releases and sharply reducing configuration incidents
   • Secured the platform with JWT authentication, RBAC authorization, strict per-tenant data isolation, and MFA
   • One of 3 founding team members; own the backend and infrastructure track and mentor an engineering intern
