Modern data architect, domain-driven design expert, standing in front of a sleek, futuristic whiteboard, wearing black-rimmed glasses, neatly combed dark hair, formal business attire with a white shirt and a slim tie, holding a silver pen, pointing to a complex system architecture diagram, surrounded by scattered papers and empty coffee cups, subtle natural light pouring through the floor-to-ceiling windows of a trendy, minimalist office, blurred cityscape in the background, shallow depth of field, cinematic composition, warm ambient lighting.
