What I'm looking for

I'm looking for an entry-level data role where I can build ETL pipelines, analyze processes, develop BI reporting, and grow my SQL, data warehousing, and data visualization skills.

I've built ETL workflows that move heterogeneous source data into data warehouses, with data cleansing and quality protocols designed to support reliable analysis.

During ETL Analyst training with Valori SPA | Forma.Temp, I designed relational databases and wrote complex SQL and PL/SQL scripts using MySQL Workbench, including joins, subqueries, stored procedures, functions, and triggers.

I use Celonis process mining to map operations, identify bottlenecks, and support process optimization. I also develop data models and quantitative KPIs for Business Intelligence reporting and strategic decision-making.

My front-end development training with BC SOFT | Forma.Temp added JavaScript, TypeScript, Node.js, and Angular capabilities for transforming JSON and XML data, integrating REST APIs, and building interactive dashboards.
