OpenMRS 3
Frontend platform work for OpenMRS, a widely used open-source EMR, with module federation, extensions, and ways for implementers to ship without forking core.

I'm Dennis Kigen, a frontend engineer building open-source health software at OpenMRS.
I work on O3, the modern OpenMRS frontend used by implementers worldwide, with a focus on frontend systems, documentation, and developer experience.

Most of my energy is going into O3 platform improvements, product-facing features, and developer experience that helps contributors move with confidence.
I'm especially interested in thoughtful frontend systems, health software, documentation, and open-source collaboration.
