Mohamed Z.

I'm a software engineer specializing in backend development, with experience building production-grade systems in NestJS and Node.js. I design and implement scalable REST APIs, complex authentication flows, and permission systems including role-based access control (RBAC) with multi-layered role archetypes. I've worked on enterprise features like audit logging, voting and quorum systems, real-time notifications using SSE and event-driven architecture, and multi-tenant data modeling with PostgreSQL and Drizzle ORM.

I'm experienced working in monorepo environments with pnpm workspaces and Turborepo, and comfortable with team-based workflows using Git, Docker, and CI/CD pipelines. I've contributed to large open-source codebases and understand how to navigate and extend complex, production-level systems — not just greenfield projects.

I care about clean architecture, maintainable code, and shipping things that actually work at scale.
