Back to original languageAbout David
Results-oriented Data Architect and IT Leaderwith over 15 years of experience designing, deploying, and scaling enterprise data platforms and cloud infrastructures. As an AWS Authorized Instructor Champion, I bring deep and specialized expertise in designing secure, resilient, and highly optimized cloud-native architectures, applying AWS best practices to solve complex business challenges.
Currently, I hold a dual high-impact role asData Architect and DevOps/SRE Architectat Mapfre. In the data domain, I am a key member of the architecture team defining the global roadmap, designing cutting-edge platforms (like Atenea v2) and developing sophisticated cloud-agnostic data anonymization engines that process sensitive information globally.
To ensure these vast data and platform ecosystems function, I act as a bridge between data architecture and operational excellence. **I technically lead the DevOps/SRE squad**, where we have successfully modernized the software development lifecycle (SDLC), **reducing platform deployment times from months to days**, and ensuring global stability.
I am passionate about evangelizing cloud technologies, reducing technical debt, and delivering tangible business value through robust engineering.
