As a professional with 9+ years of experience in data science and analytics, my journey has been characterized by a continuous drive for excellence and a commitment to delivering tangible results. I bring to me Monica Rogati's thought: "Data science is not just about data; it's about generating insights and creating impact."I hold a Master's Degree in Data Science and Modeling, complemented by a Bachelor's in Physics, which forms the bedrock of my analytical prowess. My qualifications extend beyond academia, with certificates in ITIL Foundations, ITIL Intermediate, Cobit, and Green Belt. My technical acumen encompasses various skills, including proficiency in Python, Hadoop, Impala, Teradata, SAS, Amazon Web Services, and different data analysis and machine learning techniques. Bilingual English-Portuguese, I stand poised to take on new challenges, applying my expertise and passion for data science to drive innovation and deliver impactful results. My journey is marked by a relentless pursuit of excellence and a commitment to making a meaningful difference in the data analytics world.One of my defining achievements was as a Data Scientist at Itau Unibanco, where I spearheaded the development of the Internet Banking Fraud Prevention Model. This system, which processes millions of transactions daily and ranks among the most accessed in the country, presented a formidable challenge. I embarked on a data-driven journey, collecting and dissecting internal data from the requesting department. Leveraging specialized machine learning techniques, I crafted models tailored to the Bank's precise needs, a task laden with intricacies owing to the model's unique nature and critical role within the organization. The outcomes were striking—a 20% reduction in fraudulent activities, translating into substantial savings of millions in Brazilian currency.Beyond technical proficiency, my career has honed my problem-solving skills, critical thinking abilities, and knack for bridging the gap between business and technology. Thriving under pressure in fast-paced environments has become second nature, further solidifying my consistent success and growth track record.If you are passionate about data like me, let's connect!
