01 — ABOUT

Ramadan Eweis

Cairo, EG · remote

Reliable, scalable, secure backends — and an engineer who's easy to work with.

I'm a Senior Backend Engineer with 4+ years building SaaS platforms and high-performance systems in PHP & Laravel. I specialize in secure, modular, multi-tenant architectures, database performance, and production-grade REST APIs.

I've handled complex third-party integrations and high-traffic workloads — including a platform serving 2M+ visits — with a focus on clean architecture, SOLID principles, and code that's still a pleasure to maintain years later.
