Portfolio canónico / Canonical portfolio: https://alonsomarcosm.github.io/en/

## Professional profile

Data Engineer focused on reliable pipelines, maintainable models and operable solutions. I work at Tragsatec within ImpulsaDATA for the Spanish Data Directorate, an initiative publicly reporting 5,771 published and federated datasets, 22 ministries and public bodies and 13 shared services.

My work combines Python, SQL and data modelling on PostgreSQL/Oracle with metadata ETL, CKAN, DCAT-AP-ES, RDF/JSON-LD and SHACL. It covers transformations, aggregations, views and optimisation alongside containerisation, security, test/dev/pre-production/production environments and operational documentation.

I complement this with a Master’s in Big Data & Cloud Computing, the CAPM certification and projects across OpenMetadata, Kubernetes, Airflow, Spark, Kafka, Databricks and AWS, plus applied generative AI and AI harness engineering to speed up analysis, development and documentation.

## Experience

### Tragsatec — Data Engineer · ImpulsaDATA (Spanish Data Directorate)

- 2025-10 — present
- Public sector · Spain

Data engineering and data governance in Spain’s central government. ImpulsaDATA publicly reports 5,771 published and federated datasets, 22 ministries and public bodies and 13 shared services.

**Contributions**

- Evolved and maintained metadata ETL pipelines: normalisation, mapping to common models and publishing into CKAN.
- Aligned metadata with DCAT-AP-ES and produced RDF and JSON-LD outputs with SHACL semantic validation before and after catalogue ingestion.
- Built and evolved CKAN extensions and plugins (DCAT, scheming, harvest, spatial) plus a custom plugin shared across all public bodies.
- Configured containerised stacks (Docker/Podman) and administered the team’s test, development, pre-production and production environments.
- Modelled data in SQL over the metadata model (transformations, aggregations, views and optimisation) on PostgreSQL.
- Wrote operational documentation and mentored junior profiles, with a focus on quality, maintainability and low technical debt.

### Tragsatec — Data Engineer Intern · ImpulsaDATA

- 2025-06 — 2025-09
- Province of Albacete · Spain

First stage in the ImpulsaDATA project, focused on the initial design and development of a metadata ETL converter for public-sector data-governance workflows.

**Contributions**

- Developed metadata ETL flows in Python, from extraction and normalisation to standardised JSON/JSON-LD structures.
- Mapped metadata to a common DCAT-AP-ES-aligned model and generated RDF for interoperable publishing.
- Performed SHACL semantic validation and integrated with CKAN catalogues through the CKAN Action API.
- Implemented external configuration, structured logs, technical documentation, diagrams, data dictionaries and operating guides.
