🛡️ Quality & Security (Banking Grade): Development of sensitive modules respecting banking standards (OWASP). Implementation of rigorous qualification strategies (Non-regression, ALM) to ensure "Zero Defects".

🤝 Technical Leadership: Team support, educational Code Reviews, and implementation of best practices (SOLID, Clean Architecture, CI/CD) to industrialize development.

💻 TECHNICAL STACK:
