I'm Roman Dobric, a multidisciplinary visual artist and designer specializing in AI-powered visual content and brand identity with 10+ years of experience. What I create: → Brand identity systems — logo, type, color, guidelines, tone → Visual concepts for campaigns, launches, and brand moments → AI-generated imagery&video and sound direction → Web design and digital brand presence (Figma) (Readymag) → Graphic design for any touchpoint — print, digital, social How I think: I don't start with software. I start with context — who your audience is, what cultural moment you're in, what feeling you want to create. My years of studying modern art, film, music, and design have built a visual library that lets me find the right direction fast. How AI fits in: I use AI tools — image generation, video, sound — as creative instruments, not shortcuts. They let me explore more directions, prototype richer concepts, and deliver ideas that once required full production teams. The result: bolder creative at a fraction of the time and budget. I'm the right person if you want a brand that has a point of view — not just a visual system. Let's build something worth remembering.
