01 / About
Three years of shipped systems
Three years into building production systems at BytePlus Life, a Cairo health-tech startup: a wearables data engine that has accumulated over a million records, a 63-endpoint operations API, a persona-based notification engine in Arabic and English, and the live operations dashboard the company runs on. Alongside it: a B.Sc. in Artificial Intelligence from Cairo University, ECPC 2023, and a stream of shipped side projects.
