Profile
I’m a 2D Designer & Illustrator currently at TikTok, creating exciting visual assets; text templates, stickers, effects, and other tools for character-driven content catered towards a global audience. I utilize graphic design, illustration, and AI-assisted workflows to build expressive, emotionally resonant visuals that feel human, even in an AI-powered world.
Before working in 2D, I spent years as a 3D modeler and texture artist, which gave me a strong sense of form, detail, and storytelling.
Tools I Use Frequently:
Photoshop | Illustrator | AI-assisted design tools
2D Designer
- Designed 2D assets for TikTok Photo Mode & Text Templates
