About Rene


🎯 Oracle PL/SQL Developer | I transform business needs into robust and efficient solutions

I help companies that depend on Oracle databases to optimize processes, improve performance, and guarantee the integrity of their data. My approach? Translating complex requirements into clear, scalable, and sustainable solutions.

🔧 What do I contribute?

Development and maintenance of procedures, functions, packages, and triggers in PL/SQL

Optimization of queries and processes to improve response times and performance

Functional and technical analysis to detect bottlenecks or inefficiencies

Clear documentation and maintenance oriented to facilitate teamwork

💡 My added value:

Business vision: I don't just program, I understand the "why" behind the code

Fluid communication with technical and non-technical profiles

High autonomy and commitment to quality and deadlines

📌 Types of projects I usually manage:

Maintenance and evolution of ERP systems based on Oracle

Integrations between systems using stored procedures

Data cleaning and transformation (ETL)

Refactoring legacy code to improve its performance and maintainability

I am here to make your Oracle system work better, be more agile, and give you fewer problems. Let's talk.
