I build the data systems
health decisions run on.
I'm Baba Yahaya Mohammed, a health information systems engineer at Bigvalues IT Systems. I build DHIS2 apps for the Ghana Health Service, spatial epidemiology pipelines in R, and full-stack products that take payments over Mobile Money.
01 · Selected work
Health systems first. Products that ship, too.
02 · The ecosystem I work in
From data entry to decision table.
My tools sit along the full path health data travels. Each stage below names the repos I've built for it, plus the HISP Ghana and DHIS2 community projects I've forked to work with.
03 · Live from GitHub
What I'm working on right now
Pulled from the GitHub API each time this page loads, so it stays current without me editing anything.
