Sergio Castellanos

At Dayuse, I work at the intersection of Sales and Operations to optimize our commercial workflows. My mission: empower the sales team by making HubSpot a powerful, intuitive, and integrated tool. I design and implement scalable processes in HubSpot, aligned with our internal tools and business goals. I leverage no-code tools and AI to automate repetitive tasks and improve operational efficiency. I analyse sales patterns to identify areas for improvement and drive data-informed decisions. I ensure every new workflow is well-documented, explained, and easy to adopt — so the team can fully benefit from each enhancement.
