Gerges Samuel

I build software systems,
from design to deployment.

I design and build software for different kinds of projects. I start with what the system needs to do, choose the architecture and tools to suit it, and handle development and deployment.

Architecture sketchFrom the project implementation

I’m based in Cairo and work with clients across MENA. Each project has its own domain and ways of working. I usually handle the system design, backend, frontend and deployment.

I also teach software development in Arabic as Jo Sam Code. The lessons come from things I’ve built and maintained. Content Hub started with a small problem of my own: uploading the same video four times.
