Hi, I’m Sergii — a mentor focused on programmatic advertising, especially DSP and retail media. I’ve worked across Amazon DSP, Wallmart Connect DSP, and other major platforms, building and optimizing campaigns for performance and scale. I’m here to help you navigate the strategic and technical side of retail media, from audience segmentation to full-funnel campaign execution. Whether you’re just starting out or looking to refine your approach, I’d be happy to share what I’ve learned and support your growth in the space.
