I'm Mario Ruiz Diaz, a senior principal engineer and hands-on software architect with 20+ years of experience leading large-scale distributed systems and AI-first platforms across global teams and high-growth environments. I partner closely with engineering and product leaders to translate business strategy into technical roadmaps and ensure architectural decisions support data ownership, distributed messaging, and cloud-native scale. I stay hands-on on critical paths while elevating engineering standards through observability, CI/CD discipline, reliability engineering, and AI-assisted development practices that increase velocity without sacrificing quality. I love shaping AI-first, scalable architectures that balance long-term viability with pragmatic delivery in both startup and enterprise contexts.…I'm Mario Ruiz Diaz, a senior principal engineer and hands-on software architect with 20+ years of experience leading large-scale distributed systems and AI-first platforms across global teams and high-growth environments.
