Data engineer turning complex data into APIs, ETL pipelines, and business-ready analytics on cloud platforms.
ColombiaWhat I'm looking for
I’m an Electrical engineer specialized in data engineering, with 3+ years of experience designing ETL pipelines, APIs, and analytics solutions across cloud environments (AWS, GCP). I focus on automating processes and translating data into business decisions.
In my recent roles, I’ve built Python-based automations and data-driven tools that improved traceability and streamlined team decision-making. I also optimized technical analysis processes and reduced operational turnaround time.
As a Data Engineer, I built APIs with FastAPI for ETL, data validation, and standardization. I automated scrapers and structured ingestion from PDFs and external sources, eliminating 4 hours/week of manual processing, and integrated Retool and Landbot with the OpenAI API for an AI-powered enterprise chatbot.
I’ve implemented analytics pipelines with Airflow, built interactive dashboards for business teams, and improved response times using QuickSight. I’ve also contributed to migrating and optimizing databases to Google Cloud Platform (GCP), and developed predictive models in Python to support decision-making.
