Who I Am
Engineering Principles
Mohamed Khalifa · Full-Stack Web Developer & Digital Product Engineer
-
01
Architecture First
Schemas, contracts, and boundaries before features — so the system still breathes at scale.
-
02
Performance Matters
Query plans, caching, and Core Web Vitals treated as product features, not afterthoughts.
-
03
Security by Design
Auth, validation, and least privilege baked into the architecture — never bolted on later.
-
04
Ownership
From VPS and Nginx to deploys and incidents — end-to-end responsibility for what ships.
