Alex Sosa is a Senior Product Manager with 11 years of hands-on experience blending software engineering, product design, and user research to ship web products used by millions. Based in Carolina, Puerto Rico, he has progressed through technical and product roles at BOLD—rising from Associate PM to Senior PM—and earlier combined engineering and design at startups including Rebel (acquired by Salesforce). His background in front-end development, responsive email design, and academic research in algorithms gives him a rare ability to translate complex technical constraints into elegant, accessible user experiences. He leans on data-driven discovery and agile practice to validate hypotheses and iterate quickly, while mentoring cross-functional teams to deliver high-quality interfaces. An understated asset is his early research work in computational number theory and performance-focused implementations, which informs a disciplined, analytical approach to product problems.
