Craft a futuristic text logo for "MAFI" using a bold, blocky font with a metallic finish that gives a 3D effect. Each letter should have sharp angles and facets, reflecting light and creating a dynamic appearance. The background features a sleek, abstract tech-inspired design with circuit patterns and glowing lines in shades of blue and silver, adding depth and a high-tech vibe. Use dramatic lighting to cast reflections on the letters and create a sense of movement, emphasizing the modernity of the logo.
