Hey — I'm Mohamed, a full-stack engineer based in Cairo with four years of professional experience building fintech products. Most of that time was spent at Easykash, where I owned the full payment infrastructure: integrating nine payment providers, migrating auth from JWT to Redis-backed sessions, and shipping a multi-tenant business management platform.

I'm currently contracted through PayTech Consulting to Mastercard for CIB, designing a fee-calculator — a rule-based engine that maps and processes transactional data across scheme and interchange fee structures.

Alongside that, I'm co-founding Sprynv — an AI-powered restaurant ordering platform that manages customer conversations, menus, orders, and delivery through WhatsApp and other messaging channels.

I gravitate toward backend work and system design, but I'm comfortable across the full stack. I care about correctness, observability, and keeping complexity where it actually belongs.
