# CH SumiApps

> CH SumiApps is the independent app catalog by Sebastián Cardona Henao, a Mobile Software Engineer and Team Lead based in Alicante, Spain. The site publishes information about apps built outside of his day job, and hosts his CV.

The brand name comes from *sumi* (墨), the traditional Japanese ink used for shodō calligraphy — a metaphor for clean, intentional code without noise. The site is a static page hosted on GitHub Pages.
