I build payment microservices and scalable backend platforms with PHP, Laravel, and cloud infrastructure.
What I'm looking for
At Evolvice, I build payment and platform services across the Ynmo product suite, including Ynmo Pay, a Laravel microservice integrating MyFatoorah, Tabby BNPL, banking APIs, secure webhooks, and reconciliation.
I've delivered a two-way Qoyod accounting sync with race-condition-safe upserts, deployed services on GCP with Docker Swarm and Bitbucket CI/CD, and integrated STC Bank B2B payroll, Qitaf mTLS, JeelPay, and iSpeaker Live.
Previously at REFILEX, I led engineering delivery for 18 months, setting architecture and technical standards while breaking down work, reviewing code, mentoring engineers, and translating requirements into reliable releases.
Across backend and full-stack products, I build secure REST APIs, optimize databases and caching, and deliver multilingual Arabic/English platforms using PHP, Laravel, Yii2, cloud infrastructure, and automated testing.
