Portrait of Ryu

People call me

Ryu

I build back-end systems, Rolezy, and small experiments that feel more fun when they finally work.

About me

Hi, I'm Rawi!

I'm a back-end developer, and I usually use NestJS and MongoDB for my API development. I used to work with Python, and I can also do some front-end work with Next.js. Nice to meet y'all :D

Current project

Rolezy

Rolezy is designed for the community. We believe powerful AI roleplay should be accessible to everyone, everywhere. No subscriptions. No complex setup. Just you and your stories.

More than 2,000 users have trusted Rolezy. It is a community-run project and is not affiliated with the official SillyTavern developers.

Stack energy

APIs, hosting, and motion

I like tools that feel practical first: clean APIs, simple data models, useful hosting, and a front end that still has a bit of movement.
