The xDev identity
One X.
More things to build.
xDev is where Duy builds products, explores ideas, and shares the practice of making software. One shared signature connects these activities: the blue X.
xDevKeep the signature.
Extend the expression.
The blue X is the consistent point of recognition. Lighter lettering, gently rounded joins, and open spacing balance the mark. Each product has its own name within the same visual structure.
One family of identities.
DEV is the master identity. AI Studio uses a two-line AI / STUDIO name aligned within the height of the X.

A clear structure.
DEV and AI use uppercase letters with an even stroke and gently rounded joins. The smaller STUDIO line sits beneath AI, within the height of the X. In written content, the brand name remains xDev.
Blue is the signature.
The gradient stays inside the X. Neutral lettering and backgrounds keep the logo clear and legible.

Consistency in every use.
Preserve the X
Use the original symbol, proportions, and gradient.
Choose the right background
Use the light version on light backgrounds and the dark version on dark backgrounds. Avoid visually busy imagery behind the mark.
Give it breathing room
Leave clear space of at least one quarter of the X height around the logo.
Preserve proportions
Do not stretch, rotate, outline, add shadows, or independently recolor the lettering.
Check the actual size
DEV and STUDIO must remain readable on the intended device. Use the standalone X when space is too small.
Extend the system
Add product names using the same letter construction and alignment without altering the X.
Extension study / NOTES
Room for the next idea.
NOTES explores how the identity could extend to writing and the blog. It shares the X and the same lettering rules. This is an extension study, not a newly launched product.
