About

Data Engineer with experience designing and optimizing data pipelines in cloud environments, primarily on Google Cloud Platform. I specialize in building efficient and scalable solutions that transform large volumes of data into reliable, high-quality datasets for decision-making. I have worked with tools such as dbt Core for data modeling and transformations, orchestrating workflows with Apache Airflow, and developing robust pipelines using Python and Apache Beam. I have a strong focus on optimization, both in execution time and resource usage, allowing me to design balanced solutions based on business needs. Additionally, I have experience in: Designing efficient data architectures Processing large-scale datasets Integrating APIs and external systems Publishing and processing data using services like Pub/Sub and Cloud Run Applying software engineering best practices (SOLID, DRY, KISS) Ensuring data quality through automated testing and validation I am motivated to continue growing in the data engineering field, especially in modern data architectures, distributed processing, and building solutions that create real impact.
