Sergio Encarnación SantanaBack End Developer
I have been working in the software industry since 2013, specializing in .NET technologies and SQL databases. My experience includes migrating legacy code to modern technologies, such as transitioning from .NET to .NET Core and from VB to .NET/.NET Core. I am committed to continuous learning and have a strong track record of implementing best practices and clean code in all projects I have worked on. I consider myself a team player and a self-motivated developer. Through my diverse experiences in various projects and companies, I have learned an important lesson: with dedication, attention to detail, and maximum effort as a team, we can achieve goals that initially seem almost impossible.
