Hi, I'm Rainer. I create software for digital humanists.
I help Digital Humanities researchers, DH labs, museums, libraries, and archives build tools for exploring, analyzing, and managing complex cultural data.
Developing a digital edition? Evaluating IIIF infrastructure? Planning a grant proposal? I translate research needs into practical, sustainable technology.
I work with clients at every stage of the software development lifecycle: from requirements gathering and technology assessment, to architecture, UX design, implementation, to system integration, product launch and operations. My services:
