• System Integration & Automation

  I develop and maintain REST APIs, automate processes with tools (e.g. Power Automate, Zapier), and support both internal and external systems — helping businesses reduce manual work and improve data flow.

  With experience in reporting tools (Power BI, Excel) and ERP platforms (e.g. Pronto), I support decision-making through data extraction, cleaning, and insights generation, particularly in sales, CRM, and product operations.
