At Elitesoftsys, I engineered an ERP-integrated WhatsApp messaging API that has delivered 10M+ messages across 300+ concurrent sessions. I built its high-volume dispatch with Bull and RabbitMQ, and created tools to monitor production servers and manage session and database backups.

At FirstCode, I was the sole Flutter developer for Kasir, building its social video, live-streaming, chat, and editing features. I’ve also shipped and maintained published Flutter apps at HarazSoft and contributed to client apps at Atyaf, alongside freelance apps and open-source projects.
