Pedro Garcia Santillan

Senior .NET Software Engineer with 9+ years building, modernizing, and supporting enterprise-grade applications for manufacturing, logistics and financial environments. Skilled in designing robust backend systems, performance-oriented SQL databases, and REST APIs

I have solid experience in SQL Server performance, schema design, stored procedures, indexing strategies, and data migrations. I’ve also deployed and managed applications on IIS, worked with version control tools such as SVN, and contributed to system integrations and legacy modernization projects.

I’m used to working closely with stakeholders to translate requirements into functional software, ensuring maintainability, security and long-term scalability. I’m committed to continuous learning and enjoy tackling complex technical challenges.

I’m currently open to remote international roles where I can contribute my experience in .NET development, backend engineering, and system modernization.
