How I work

I conceive and art-direct every design, choosing the concept, tone and wording. I develop the artwork using AI tools (Claude, ChatGPT and Kittl), incorporate appropriately licensed fonts and graphics, and prepare high-resolution, print-ready files.

Before listing any product, I review intellectual property rights, and I don’t use third-party characters, trademarks or identifiable individuals in my designs.
