What I'm looking for

I seek a role that fosters innovation and collaboration, with opportunities for growth.

I am a seasoned data professional with over 8 years of experience in the data domain, having worked with renowned companies such as Itaú Unibanco, Nestlé, and Ifood. My journey has been marked by a commitment to excellence and a passion for leveraging data to drive business insights. Currently, I serve as a Senior Data Scientist at ThoughtWorks, where I collaborate with the Mercedes Benz USA team to enhance data-driven decision-making through model tuning and feature engineering.

Previously, I led the data science team at Ifood, ensuring timely and quality deliveries while aligning closely with CRM stakeholders. My role involved not only technical expertise but also strategic leadership, as I organized the team's roadmap and supported solution design initiatives. At Nestlé, I further honed my skills as a Data Scientist Manager, focusing on digital transformation and team development, which included hiring and mentoring new data scientists.

My educational background includes a Master's degree in Computer Science from the University of São Paulo, where I contributed to significant research in audio data classification. I am passionate about fostering collaboration within teams and building strong relationships with stakeholders to achieve shared goals.
