Marc Rodriguez Sierra

Engineering Director with the soul of an architect and an active developer. My career is defined by leading high-performance teams from the front lines of code, balancing strategic management with the technical design of complex solutions. Expert in building systems from the ground up—such as a columnar database engine—and modern data analytics platforms driven by Agentic AI.

My approach is deeply technical: I design zero-manual-effort QA strategies, optimize CI/CD pipelines, and deploy advanced stacks. As a lifelong learner of new technologies, I am convinced that the best way to lead an engineering team is by being a key contributor to technical excellence and product innovation.
