What I'm looking for

I'm looking to build reliable, automated data solutions using Microsoft Fabric, Azure, Python, PySpark, and SQL, with ownership of ingestion, transformation, data quality, monitoring, and analytical modeling.

At Core Analítica, I build end-to-end Microsoft Fabric and Azure Data Factory pipelines for financial, operational, and production data.

I integrate SQL Server, Azure SQL Database, BigQuery, files, and APIs while building validation, reconciliation, monitoring, and publishing processes that provide reliable data to analytics and data science teams.

I led a generative AI solution for immigration program evaluation using Python, Microsoft Fabric, Azure Key Vault, official sources, and the OpenAI API. The successful demo converted the proof of concept into a new company contract.

I've also automated Fabric dataflow and pipeline deployment with SemPy, reducing setup and validation for about 100 tables from roughly three hours to seconds. I work across PySpark, Databricks, SQL, medallion architecture, Lakehouses, Warehouses, and secure analytical models with Row-Level Security.
