About Javier

Hello,
I am a systems analyst passionate about programming, as it allows me to offer real solutions to companies' technological challenges and contribute directly to the improvement of their processes.

Throughout my experience, I have worked in different areas of development, from automation with macros and VBA (Excel and Access) to the creation of applications in Visual Basic .NET, C#, and the use of databases such as Microsoft SQL Server and MySQL. Currently, C# is the language with which I have carried out most of my projects.

I hope this brief summary gives you an idea of how I can add value. It will be a pleasure to collaborate with you and have the opportunity to help you.
