A messy database is a liability. I design and build PostgreSQL systems that are not just functional, but optimized for growth and security.

As a Data Specialist from the National University of Quilmes (UNQ), I focus on creating robust architectures. Whether you are starting from scratch or need to fix a broken structure, I ensure your data is organized, protected, and ready for high-performance analysis. I recently led a database normalization project for an NGO, migrating complex legacy records into a scalable 1:N architecture with zero data loss.

What I offer in the basic service:
• Professional ERD modeling to eliminate redundancy and ensure data integrity.
• Clean SQL scripts (DDL) for tables, primary keys, and basic constraints.
• Security-First approach focusing on best practices for data protection.

I build scalable engineering designed to handle from thousands to millions of records, ensuring your system is analytics-ready for tools like Power BI or Looker Studio.

PLEASE CONTACT ME BEFORE ORDERING to discuss your specific architectural needs.

BASIC SERVICE: THE ARCHITECTURAL BLUEPRINT
To ensure transparency, the basic service includes only the structural design:
• Professional ERD (Entity-Relationship Diagram): A logical map of your data.
• Database Normalization (3NF): Elimination of redundancies to prevent future errors.
• Standard Documentation: A clear guide on how your tables should interact.
• Up to 5 Tables: Perfect for small apps or specific business modules.

Stop losing time with messy spreadsheets and start making data-driven decisions. I am a Data Analyst specializing in transforming raw, chaotic information into streamlined systems and professional visual reports. Whether you have a broken Excel file or need a full SQL database architecture, I provide clean, scalable, and secure solutions. What I can do for you: Data Cleaning & Automation: I use Python to clean, format, and normalize complex datasets (Excel/CSV). Business Intelligence: I build interactive dashboards in Looker Studio and Power BI that turn numbers into clear insights. Database Architecture: I design and migrate data to robust SQL structures (PostgreSQL/MySQL), ensuring data integrity and security. Why work with me? I don't just "move data." I audit its integrity. I recently led a full-scale data migration for an NGO, moving their entire financial management from static Excel files to a relational PostgreSQL system. My tech stack: Python (Pandas), SQL (PostgreSQL), Looker Studio, Power BI, and Data Security (Masking). Got a project in mind? Send me a message, and let’s discuss the best way to organize your data.
