SUJIN LEE

Hi, I'm Sujin.

AI application and web developer. I build tools that reduce repetitive work in content production and AI chat. I lead problem definition, design, and verification, and use AI coding tools during implementation.

Personal portfolio | LinkedIn

Three extensions for Risu, an AI chat frontend: turn conversations into audiobooks, explore inner thoughts, and switch reading themes.

Audio Book Maid library and resume playback controls, running the real UI with synthetic demo data.

Real UI, synthetic demo data. No private conversations.

  • Audio Book Maid: Assign voices, review scripts, generate audio, and pick up where you left off.
  • Doki Doki: Generate, save, and reopen inner thoughts for a selected response.
  • PocketRisu Theme Switcher: Apply presets, use dark mode, and restore your original theme.

How I work

I studied video design and worked as a video content designer. Production experience shapes the tools I build for content work and everyday tasks.

I handle problem definition, feature design, implementation with AI agents, and result validation. Claude Code and Codex are my go-to agents.

Validation scope and licenses

The documentation distinguishes independent Linux installation and tests from browser simulations. Untested scenarios, including physical iPhones and fresh GPU setups, are listed in each repository and the Risu compatibility guide. Check each repository's supported environments and license before use.
