Saif Zidan

I am an executive developer specializing in emergency DevOps rescue, containerized deployments, and robust backend architecture. I step in when systems fail, scale poorly, or need rapid deployment.
Recently, I have served as the executive developer for the iSeries enterprise ecosystem, managing extensive codebase refactoring and remote access testing. My core expertise lies in low-level systems engineering—specifically designing diskless storage architectures using LVM and iSCSI targets, and optimizing network boot architectures.
I am highly experienced in:
Diagnosing and resolving Nginx and Apache reverse proxy conflicts, including secure port binding and automated SSL (Let's Encrypt) renewals.
Building high-throughput, asynchronous API services and relational schemas using FastAPI, SQLAlchemy, and SQLite.
Deploying, securing, and maintaining open-source enterprise systems (Mayan EDMS, Apache Guacamole, Frappe ERPNext).
Configuring multi-site network bridges and deploying stable containerized database stacks via Docker.
I am looking for short-term, urgent technical rescue contracts, architectural consulting, or full-time remote roles. If your server is dropping traffic, your containers are crashing, or you need immediate enterprise deployment support, I can execute today.
