Modern cache design, computer architecture, problem-solving concept art, futuristic laboratory setting, sleek metal tables, rows of high-tech servers, bright LED lights, complex circuit boards, wires and microchips scattered around, a giant screen displaying system architecture diagrams, a brilliant engineer, mid-30s, short brown hair, glasses perched on the end of his nose, wearing a white lab coat, standing with hands on hips, looking at the design blueprint, pencil tucked behind ear, intense thinking expression, warm ambient lighting, shallow depth of field, cinematic composition, futuristic ambiance.
