Flat vector avatar portrait of a man with round glasses and beard

Create a clean, front-facing vector avatar of a young man in a contemporary flat illustration style. The portrait is perfectly centered and cropped from the upper chest upward, with the subject filling most of the square frame. Use bold geometric forms, smooth color transitions, crisp edges, and a balanced, symmetrical composition. Facial features should be simplified yet expressive, with clear eyes, subtle shadows, and natural skin tones. He has thick brown hair brushed back neatly, a well-groomed full beard, and wears round black eyeglasses with a plain black crew-neck T-shirt. Place him against a solid warm orange background with no patterns or objects. Maintain a polished digital avatar aesthetic inspired by modern vector artwork, featuring vibrant colors, sharp lines, minimal detail, and absolutely no photorealistic textures. High-resolution, 1:1 aspect ratio, suitable for a professional profile image.
