Professional Banner Design for Sdr Portfolio with Tech Mockups

We are seeking a talented graphic designer to create a clean, modern, and professional banner for a freelance Sales Development Representative (SDR) portfolio. The design should convey trustworthiness and a tech-oriented approach. The background should feature a soft aesthetic gradient in shades of corporate blue and white. On the right side of the banner, please include high-quality, professional mockups of a laptop and a smartphone screen. These screens should display clean CRM pipelines, sales dashboards with clear charts, and organized columns such as 'New Lead' and 'Meeting Scheduled'. It is crucial that the design maintains a polished and clean look, with absolutely no text or words included on the image itself. The final banner will be used as a profile visual for a freelance professional.
