About Diego

I am a .NET developer with over 8 years of corporate experience, specializing in business management software and SQL Server databases.

I currently work developing and maintaining management applications used in real business administration and control environments, which allows me to bring a practical, business-oriented vision, not just code-focused.

How can I help you?

🔹 SQL Server database optimization
🔹 Performance improvement in queries and stored procedures
🔹 Maintenance and evolution of VB.NET applications
🔹 Bug fixing in management software
🔹 Automation of business processes and reports
🔹 Refactoring and improvement of legacy code

I am accustomed to working with business-critical applications, where stability, clarity, and efficiency are priorities.

I do not develop “experimental projects,” but practical solutions that must work in a company’s day-to-day operations.

My approach

✔ Clear problem analysis
✔ Realistic and maintainable solutions
✔ Direct and professional communication
✔ Clean and well-structured deliveries

If you need ad-hoc support, continuous maintenance, or to resolve a specific issue in your application or database, I will be happy to help.
