About

I'm Massourang Sourang — engineer, founder, and builder based between Paris and Dakar. I started coding in 2017, shipped my first production system in 2019, and haven't stopped since. I led technical teams at Groupe Référence (2020–2025) and now focus full-time on SenDocteur, a healthcare platform serving hospitals in Senegal. I care about software that works, scales, and actually gets used.
