Isaya Mollel
Technology and Data Manager, D-tree International
Software engineer and digital health leader in Tanzania, working on community health systems, health data governance and AI in health.
About
I am a software engineer and digital health leader based in Tanzania. My work sits where technology meets community health: the systems health workers use every day, the rules that keep health data safe, and the careful use of AI.
I have more than 10 years in software development, including over 7 years at D-tree International in Tanzania. I lead D-tree's technology and data work in Tanzania and coordinate engineering across D-tree's country offices. I work with the Ministry of Health, government ICT units, NGOs and technology partners to design, build and run digital community health systems.
Languages: English and Kiswahili, both at full professional level, spoken and written.
