About Pedro Mariano

I am a data scientist driven by curiosity and a constant desire to learn. Graduating at the top of my class in Physics from USP, it was during my studies that I fell in love with programming and began applying data science in my research. Since then, my goal has been to continuously grow and evolve, generating real value for companies and their clients.Currently, I work in CRM process automation, using tools like Databricks, PySpark, and SQL in cloud environments, providing services to Natura & Co. I am responsible for conducting data analyses that generate valuable insights for the company, supporting strategic decision-making. My primary goal is to deepen my knowledge of predictive machine learning models, a field that captures my greatest interest. To achieve this, in addition to my work, I dedicate myself to personal projects that allow me to explore and master the most relevant and advanced technologies in the field of data science. Additionally, I am exploring the development of cloud applications using AWS infrastructure, expanding my skill set.My education and experience have provided me with a solid foundation in analytical thinking, problem-solving, statistics, algorithm development, effective communication, and fluency in English. I am committed to continuing to apply and enhance these skills, always seeking new opportunities to innovate and contribute to the success of the projects I am involved in.Skills:PythonSQLJoinsAggregationsSubqueriesORMsPandas MatplotlibNumPyFoliumMachine LearningTensorFlowKerasData preparation Feature engineeringProblem framingLogistic regressionRandom forestsNeural networksKNNLinuxBashGitFramework ROOT (C++)Algorithms Problem solvingComunicationPlanning Team workFluent EnglishNative PortugueseBegginer FrenchProfessional ethicsMotivated by challengesResilientR OctaveMathematicaMATLAB

    In my role at IBPAD, I provide services for Natura & Co and I am responsible for several key activities in the fields of Data Engineering and Data Science:- As a Data Scientist, I am responsible for conducting data analyses that generate valuable insights, supporting strategic decision-making to increase the profitability of the client company. For this, I work with large databases using SQL, Python, and PySpark.- One of the most impactful projects was the development of a code to measure CRM performance, which resulted in a significant optimization: the execution time, which previously took a week, was reduced to just two hours. This project involved extensive work with SQL, Python, and PySpark, as well as executing ETL projects between BigQuery, Drive, and Databricks.- I identified areas for internal improvement and developed systems to automate ETL processes by integrating cloud services. This automation not only significantly reduced the time required to carry out these processes but also minimized human errors, increasing efficiency and reducing operational costs.- In dealing with large-scale databases in Databricks, I employed techniques such as partitioning and 'Z-ordering' to optimize them. I also used parallelization to optimize processing. These practices resulted in significant improvements in system efficiency and performance.All these activities were carried out using skills in Python, SQL, and Spark, mostly on the Databricks platform, demonstrating the application of technical knowledge to solve complex problems in the field of data science.
