02 / About

I'm learning to build with intention.

I'm an aspiring software developer based in the UAE with an interest in application security, practical AI and product development.

I enjoy turning unclear real-world workflows into focused software—and documenting the decisions behind what I build.

01
Useful before impressive

Start with the workflow and the person experiencing it.

02
Security as a design decision

Make identity, authorization and data boundaries explicit.

03
Document the reasoning

Good decisions become repeatable when their context survives.

03 / Technical toolkit

Tools I build with.

Technologies used across working projects, tested prototypes and current development.
