The immunisation report in AI-SDHMS Data Quality Module
How the immunisation report in AI-SDHMS Data Quality Module turns a monthly DHIS2 export into the South West EPI review documents, and what it refuses to invent.
The malaria data review in AI-SDHMS Data Quality Module
What the malaria feedback letter in AI-SDHMS Data Quality Module checks, and why a blank in the DHIS2 extract is not written as zero.
Why I built AI-SDHMS Data Quality Module

The reproductive health review in AI-SDHMS Data Quality Module
What the reproductive health review in AI-SDHMS Data Quality Module scores, and what the meeting slides keep so a facility can be given a corrective action.

I Built a Financial Management Tool as a District Medical Officer Because Nothing Adequate Existed for Cameroon
Every Category 3-5 health facility in Cameroon manages Recettes Propres manually, prone to error. I built an offline HTML tool that automates the six-step calculation and runs a six-way triangulation audit — before the IGF arrives.
I Built a Free Reproductive Health Data Quality and Performance Review Tool for DHIS2 Users
An Excel-based tool that turns one month of DHIS2 aggregate data into structured quality checks, performance scores, facility-level issue summaries, and corrective action prompts — no formulas required.
