Cloud Security Engineer at Ayesa Digital, securing AWS environments and designing cross-cutting security for enterprise AI platforms.

Spain

Message

At Ayesa Digital, I work across security infrastructure, AI platform security, and compliance. I defined and implemented cross-cutting security for an enterprise AI platform spanning LLM-serving infrastructure, RAG pipelines, vector stores, agent orchestration, and MCP tool access.

I previously operated and secured a multi-account AWS estate for an energy-sector client, helping keep its security score above the 75% KPI through daily findings review and coordination with account teams. I also participated in deployments and migrations, with a focus on continuity and operational stability.

Alongside my professional work, I design and build AI agents and RAG systems in Python. My projects include a knowledge agent with source-cited answers and human approval for side-effecting actions, and a chemistry research platform integrating models, datasets, and research tools.
