01At work · Alfanar

Medium-voltage switchgear, from schematic to shop floor.

At Alfanar's Secondary Switchgear Factory I own the electrical design of each order I'm assigned, from the first schematic until the unit leaves production.

S1Step 1 / 4
Design
Electrical schematics for each customer order, built to the customer's and the utility's specifications.
S2Step 2 / 4
Approval
Drawings go to the customer for review; I resolve their comments until sign-off.
S3Step 3 / 4
Release
The full production package: drawings, wiring and ferrule lists, labels, and the bill of materials in SAP.
S4Step 4 / 4
Support
Design point of contact for QC, testing, and production until the unit ships.

AIAutomation

Alongside the design work I build AI-assisted tools that automate routine design checks and documentation for the team, so errors are caught before they reach production.

02Products

Software I designed, built, and ship.

End-to-end products with real users: backend, web, and mobile, released and maintained by me.

Reading Marathon

An Android App for Reading Groups

An Arabic Android app for reading with friends: log today's minutes in one tap, and they count in every group you belong to. Groups read a shared book, with a ranking and an activity feed. It replaced a Streamlit dashboard fed by Google Forms.

01One-tap logging, a reading timer, and quick-log buttons in the reminder
02Groups with roles, invite codes and public discovery, on Firebase with tested security rules
03Scoring and statistics in a pure-Kotlin module with unit tests
04Imports the group's old Google Form history
