Aloysio Guilherme

Data professional with 5 years of experience turning raw data into reliable, actionable information — starting as a Data Analyst and, over the last 2 years, expanding into analytics engineering by taking direct ownership of ETL/ELT pipelines, data modeling, and transformation layers. Throughout my career as an analyst, I developed a strong foundation in SQL, business intelligence, and KPI-driven reporting — working cross-functionally to deliver dashboards, automate workflows, and surface insights that directly influenced operational and strategic decisions. That day-to-day proximity to data quality issues and pipeline bottlenecks is what naturally led me toward the engineering side of the stack. Since 2024, I have been designing and maintaining data pipelines, building transformation models with, orchestrating workflows and integrating sources, while continuing to support the analytical layer. To consolidate this transition, I pursued a Postgraduate degree in Analytics Engineering (completed August 2025), deepening my expertise in cloud infrastructure, data warehouse design, modern data stack, and modern ELT architecture using dbt, Airflow, Airbyte, Snowflake, BigQuery, AWS, and Docker. I thrive in environments where engineering rigor and business context meet, building data products that are not only technically sound but genuinely useful to the teams relying on them.
