Jesus Castillo

I am a professional with extensive experience in the IT field, having worked in all layers of the trade: from equipment repair to the design of complete architectures focused on performance, resilience, and cost optimization.

I have led ISO 27001 implementations, managed annual audits with continuous improvements, and coordinated outsourcing and transition processes to external teams.

I have also directed migrations to cloud environments (Azure and AWS), modernization of collaborative and compliance platforms (Microsoft 365, Teams, SharePoint, Exchange Online, Purview), and adoption of serverless architectures.

AI is part of my daily life: I have integrated its capabilities into my workflows to increase productivity without compromising security or data protection.

Furthermore, I managed the technical recovery from a ransomware attack that encrypted all production systems. Thanks to a well-designed disaster recovery architecture, we were able to restore operations in just three days.

All this experience has taught me that technology must serve three objectives: security, compliance, and productivity, always with resilient systems that ensure business continuity.

If you are looking for someone who can combine strategic vision, real-world experience, and technical execution, I can help you.
