Carlos Gonzalez Portela

I’m a Junior Data Engineer focused on building and operating data pipelines that move reliably in production. I combine strong SQL/query optimization with hands-on automation to reduce runtime and improve data availability.

In my current role as a Software Engineer (.NET Ecosystem) at Seidor, I designed and developed an automated ETL data management pipeline integrating complex business logic—cutting a critical multi-hour process to under 2 minutes (~95% performance improvement). I also refactored legacy .NET REST endpoints to expand exposed datasets and achieve a 50% reduction in data retrieval response times.

Previously at DLTCode, I redesigned the notification engine to double the volume of processed and delivered events without increasing latency by refactoring the dispatch logic in NestJS and optimizing the persistence layer. I integrated multiple databases (PostgreSQL + MySQL) via schema normalization and a unified access layer, delivering 30–40% performance improvements in cross-system queries.

I work efficiently with AI-assisted development tools like Copilot and Claude CLI to accelerate problem-solving, while maintaining robust validation, error handling, and consistent data contracts. I’m currently leveraging a stack across C#/.NET Core and TypeScript/NestJS, and I hold a B.S. in Computer Engineering from the University of Vigo (EURO-INF Label) with a capstone project on trip planning and route optimization.
