About Ahmed Abdelkafi
I treat an interface the way an architect treats a plan: every line has a reason, every measure is checked, and nothing ships until it holds up under real use.

02
Measured, not guessed
Performance is a number: 45% fewer server requests, 30% faster rendering, 60 FPS timelines. I profile first, then optimise.
03
Secure by default
Server-enforced roles, two-factor auth, audit logs, row-level security and validated input, on every action, not just the UI.
04
AI with review
I use Claude Code, Cursor and Copilot every day, and every generated change is read, tested and owned before it reaches production.
SC.03 — How I buildFrom the browser to the database
One developer, the whole stack.
I design and ship every layer of a product: the interface, the API, the database, the infrastructure, and the tests that hold it together.
