Selemondev

Hey there! I am Selemon Brahanu, but you might know me as selemondev. I'm a frontend engineer building intuitive user interfaces and an open sourcer. I have built libraries with over 204.1K downloads, VSCode Extensions with 32.5K installs and projects with 1.2K stars on Github. I mainly focus on the Javascript/Typescript ecosystem building tools for myself and others while contributing to tools that improve the developer experience. I care about building systems that work, solving real problems, and making sure the final product feels as good as it looks.
