Who I Am

I'm an Applied Statistics student at Mansoura University, but my real classroom is every messy dataset I get my hands on. I'm currently training as a Data Engineering Trainee at DEPI (Digital Egypt Pioneers Initiative) and a Data Analysis Trainee at NTI — building the two halves of the same craft: getting data in, and getting insight out.

Along the way I've worn a few other hats: freelance digital marketer, penetration tester, and AI trainer working on RLHF projects to sharpen LLM reasoning. That mix keeps my engineering practical — I design pipelines and analyses that are meant to be trusted, secure, and actually used by people making decisions.
