Modern Logo Design Needed

I need a sleek, contemporary logo that instantly feels fresh and up-to-date. The overall style must be modern—clean lines, balanced proportions, and a professional finish. I’m wide open on colours, so please recommend a palette you feel best supports the concept. Likewise, the execution can be a wordmark, an icon, or a clever combination of both; what matters most is that the final mark is memorable and scales well from social-media avatars to large print.

Please provide:

• 2–3 distinct initial concepts
• Up to two rounds of focused refinements on the selected direction
• Final files in AI, EPS, SVG, PDF, and high-resolution PNG with transparent background
• A brief rationale explaining type, colour, and layout choices

If you typically work in Adobe Illustrator, Figma, or similar vector-first tools, that’s perfect. Looking forward to seeing how you translate “modern” into a distinctive visual identity.
