What I'm looking for

I am looking for a role that fosters collaboration, encourages innovation, and offers opportunities for professional growth in data analytics.

As a seasoned Data Engineer with over five years of experience at Mercado Livre, I have consistently driven high-impact metrics and collaborated with development teams to enhance service quality and performance. My expertise lies in solving complex technical challenges while aligning them with business objectives to elevate customer satisfaction. I am passionate about data analysis and continuously seek innovative ways to improve metrics and indicators.

Throughout my career, I have successfully implemented various strategies that have led to significant operational improvements. For instance, I increased SLA compliance by 5 percentage points and reduced downtime by 50% through rigorous analysis and the introduction of a cycle-based approach for bug resolution. My collaborative spirit and adaptability have allowed me to thrive in dynamic environments, and I am always eager to learn and contribute to a team-oriented culture.
