About

Hello there! I am Jairus Joer, a Senior Software Engineer and Designer based in Germany with 8+ years of experience. I care deeply about software that feels thoughtful in every layer: clear in its structure, expressive in its interface, respectful of the people who use it, and deliberate in the way it supports real work.

The work I delight in most sits at the intersection of user experience, accessibility, design systems, and developer experience. I enjoy shaping systems that make taste practical, whether through refining interfaces, building resilient foundations, or creating tools that disappear into the flow of thought.

Previously at HERO Software, I led the adoption of design systems, monorepo orchestration and platform modernisation across multiple engineering teams. Currently at BWI, I am supporting Germany’s digitalisation efforts by developing open-source software for various connected codebases.
