Hi, I'm Rizumu Ayaka (小音 Little Sound)
I'm a frontend engineer and Vue contributor with 8 years of development experience. At Comfy Org, I built complex, interaction-heavy interfaces for ComfyUI while contributing to Vue's next-generation rendering architecture.
I build projects from scratch, lead small teams and open-source collaborations, and turn ideas into physical products through CAD and 3D printing.
Beyond coding as a profession, I pursue tech trends globally through conference engagements and personal experimentation. This passion drove me to create an award-winning AI development tool and integrate AI workflows to supercharge productivity.
