I refactored and optimized SQL queries to enhance database performance and improve data retrieval speeds. I developed and implemented new, efficient queries to support data analysis, reporting, and decision-making processes. These optimizations were successfully integrated into the software, achieving greater system efficiency and smoother data processing. Additionally, I collaborated with the development team to ensure the seamless implementation of these improvements.

I coordinated a team of developers, leading the architecture and implementation of complex and scalable data flows. I modeled data and created ETLs for a new system that consumed real-time data from various sources. I developed and maintained robust data pipelines, establishing a solid and consistent backend using Python, Node.js with Nest.js, and AWS Cloud.I closely collaborated with stakeholders to identify data requirements, define KPIs, and create interactive dashboards, providing valuable insights for strategic decision-making and contributing to a collaborative and productive work environment.I implemented automation solutions that optimized ETL processes, resulting in a significant reduction in operational costs and processing time. I utilized tools like Git for version control and agile methodologies like Kanban and Scrum to manage and organize projects.

Created data pipelines and data transformations to streamline data flow and enhance data quality for machine learning models, while integrating these processes seamlessly into web applications to support real-time analytics and intelligent features.
