What I'm looking for

I seek roles building scalable data platforms and pipelines using Python, SQL, Databricks and cloud services, with opportunities to lead technical projects and continue learning.

I am a Data Engineer with a degree in Electronic and Telecommunications Engineering and a Master's in Artificial Intelligence in progress, committed to continuous learning and technical excellence. I have driven migrations from Redshift to Databricks, refactored legacy systems using Azure and Databricks, and built scalable data lakes, pipelines, ETL processes, dashboards, and standardized data models.

My work delivered measurable impact including over $300,000 annual savings from a major refactor, promotions to Senior Data Engineer and Tech Lead, and multiple certifications (DP-900, AI-900, Databricks Data Engineer Associate, Airflow 3 101). I combine strong software-engineering fundamentals with expertise in Python, PySpark, SQL, Databricks, AWS and Azure components, Terraform, Airflow, and API frameworks to produce reliable, production-grade data platforms.
