Contributions to the data platform and AI systems supporting the scientific and administrative operation of the Gran Telescopio Canarias. I work at the boundary between infrastructure, data engineering and on-premise agentic systems.

• Built an agentic assistant for evaluation and assisted drafting of technical tender documents, based on RAG over embeddings stored in a vector database. Cuts the team’s manual workload by ~50% and delivers full traceability. The system runs 100% on-premise, with no dependency on external APIs and no exposure of sensitive data.
• Contributed to the corporate Deltalake with large real-time volumes of data, consolidating a single analytical source of truth that serves multiple domains and use cases across the organisation. This democratised access to that data and enabled on-demand cross-referencing of information from different sources.
• Designed a digital tool for operational procedures with role separation (manager / operator), version control and execution traceability. Reduces operators’ cognitive load and unifies drafting, publication, execution and audit of critical instructions.
• Built an asynchronous coordination platform for team leads to validate telescope usage and performance statistics by cross-referencing multiple operational sources. Removed the dependency on periodic meetings and Excel-based reporting, giving each lead an auditable view to review on their own schedule.
• Deployed LLMs as an internal service on a shared GPU cluster (SLURM), with on-premise observability. Opens up generative-AI capabilities to the rest of the teams with no per-token cost and no data leakage.

Applied scientific analysis for municipal services in the aftermath of the 2021 Tajogaite volcano eruption on the island of La Palma. I built the data infrastructure that the emergencies department used for weekly decisions on the affected areas, and delivered findings that changed the post-eruption habitability protocol.

• Automated weekly reporting of air quality and CO₂ with Python + ArcGIS Online. Eliminated ~12 hours/week of manual work and turned volcanic monitoring at Puerto Naos into actionable data for 6+ non-technical stakeholders.
• Discovered through EDA a Pearson correlation of ~0.6 between coastal CO₂ and tidal cycles, a previously undocumented gas-accumulation mechanism. Led Emergencies to revise the safety protocol for inhabited coastal areas after the eruption.
• Designed interactive dashboards in Power BI and Tableau for emergencies, waste management and HR (1000+ employees). The CO₂ dashboard became the emergencies team’s go-to tool for their daily habitability decisions.
• Standardised a historical dataset of 3M+ records from the meteorological portal, recovering analytical continuity back to 2016 (first IoT rollout). Designed the proposed PostgreSQL schema to evolve the system.

One-to-one tutoring for secondary-school (ESO) and pre-university (Bachillerato) students. In-person and online, with on-demand remote support during exam periods.

• Students across several academic years in mathematics, physics and chemistry, with personalised follow-up and consistent results in main exam sessions.
• Mixed in-person and online delivery, with on-demand remote availability during critical exam windows for quick questions outside regular hours.
• Self-authored sets of notes with step-by-step worked examples and additional problems for students to solve on their own, aligned with EBAU content.
