Who I am

I'm a 15-year-old self-directed developer from Egypt, building software that solves real problems — not tutorial projects.

I specialize in Python automation and data tooling — writing clean, well-documented CLI scripts and pipelines that make messy data usable. I care deeply about code quality, error handling, and real-world usefulness.

I'm currently working through a structured learning path: Python mastery → data analytics → AI/ML → full-stack web. Every step involves shipping something real, not just watching videos.

I learn by building, ship fast, and document everything. Targeting MIT. Every line of code is part of the application.

Things I've Built

001 v2.0

CSV Cleaner CLI

Production-grade Python CLI for automated CSV data quality. Two variants: a zero-dependency stdlib build and a vectorized pandas engine. Strips whitespace, flags bad values, catches missing fields, removes duplicate IDs — always producing a clean file and a flagged file with exact error reasons per row.

v2.0 — What's new
N/A added to bad value detection
Pandas variant with full feature parity
Duplicate errors now include the duplicate value
7 pytest tests across both variants
Python 3.9+Pandas CLI ToolStdlib + Pandas Pytest · 7 Tests
