Andres C.

Data Engineer & BI Developer with 3 years of hands-on experience building analytics and ETL solutions in fintech, on top of a broader base of 10+ years in backend software development (Python, Java, Node.js). At Fide PBC, a fintech company, I worked as a Data Engineer / BI Analyst: designing ETL pipelines with Python, managing data in MongoDB and PostgreSQL, and building advanced Power BI dashboards (DAX: LASTNONBLANK, HASONEVALUE, SWITCH, Power Query) to track a user activation funnel for a platform with 150K+ active users, plus REST API integrations for automated reporting. What I specialize in: - Power BI dashboard design and advanced DAX - Python-based ETL and data cleaning/transformation - SQL across PostgreSQL and MongoDB - querying, modeling, and optimization - REST API integration for data pipelines I'm also completing the IBM Data Engineering Professional Certificate, building familiarity with Spark, Kafka, Airflow, and Hadoop. I communicate clearly in written English and work well in async, detail-oriented collaboration. If you need someone to turn raw data into clear dashboards and reliable pipelines, let's talk.
