Hi, I'm Andrew Saba 👋

Software Engineer · Backend & Enterprise Systems · Node.js · PostgreSQL · Android

About Me

I'm a software engineer based in Cairo, Egypt, specializing in high-performance backend systems and enterprise application development. I'm currently building production-grade cloud add-ons at RAPTORS Tech, where I've re-engineered core processing pipelines to cut execution time by up to 70% and shipped full-featured enterprise modules used in real payroll and HR workflows.

I enjoy working on problems that sit at the intersection of architecture, performance, and real user impact — whether that's redesigning a legacy calculation engine, training a content classification model, or building a geo-fencing Android app from scratch.

  • 🔭 Currently working on SAP CAP enterprise add-ons (Clearance Management, Payroll Engine)
  • 🧠 Interested in backend architecture, distributed systems, and applied ML
  • 🎓 B.Sc. Computer Science — Ain Shams University (2024)
  • 📍 Cairo, Egypt · Open to remote opportunities
