Software Engineer focused on backend systems, data pipelines and geospatial solutions.
EU citizen, based in Spain. Available for Backend, Data Engineering and GovTech roles.
I design and implement production-oriented software with emphasis on reliability, scalability and clear architecture.
My work combines backend development, data processing and spatial systems, with hands-on experience in real-world, non-academic projects.

Civic-tech platform for public issue reporting and citizen participation, integrating geolocation, backend APIs and structured data persistence.
Designed with a focus on data integrity, spatial context and extensible backend architecture.
Technologies: Backend APIs, PostgreSQL/PostGIS, frontend application, Docker
Platform that analyzes job listings to extract and rank the most demanded technical skills for a given role.
Emphasis on data ingestion, normalization and analytical pipelines rather than visualization.
Technologies: data ingestion, processing pipelines, analytical modeling
This section groups university projects and learning-oriented repositories created during my academic and professional development.
They are kept for reference and transparency, but do not represent my current production standards or architectural practices.
Repositories containing early-stage ideas, prototypes or technical explorations.
These projects focus on experimentation and problem exploration rather than finished, production-ready solutions.
