This resulted in a 50% reduction in the time spent by billing analysts on personalized report generation, allowing them to focus on more strategic and high-value analyses.I bring expertise in a variety of technologies and practices, including:Development of data pipelines using Pandas, Apache Spark, PySpark, and Airflow for automation orchestration.Experience in parallel processing using threads for performance optimization.Implementation of queue systems such as Celery and RabbitMQ for task management.Use of relational databases like PostgreSQL for efficient data storage and manipulation.Use of SQL for querying and inserting data into databases.Development of REST APIs with DjangoRestFrameWork, Flask; consumption of APIs on Marketplace platforms like MercadoLivre, PluggTo, and GraphQL APIs on platforms like Pipefy for project management.Agile methodologies (Scrum) and use of tools such as Jira and Confluence.Code versioning with Git.I am always seeking to learn new technologies and stay updated with market trends.
