Summary

Rockstar🎓
Top SchoolMario Casciaro is a seasoned software leader with 12+ years of experience building and scaling developer-facing and mission-critical products, currently serving as Vice President of R&D in Dublin. He combines hands-on engineering roots—from low-level C/C++ at IBM to leading the first line-of-code implementation of D4H Incident Management—with strategic product and GTM experience as a founder and former CTO. Author of the best-selling Node.js Design Patterns, he is a respected voice in the Node.js community and an active open-source maintainer who has improved security and functionality in utilities like object-path. Mario has repeatedly turned prototypes into production revenue, founding startups (one acquired) and shipping enterprise-grade SaaS used globally for crisis management. Comfortable bridging engineering, product and executive stakeholders, he brings a pragmatic focus on secure, performant systems and developer experience. An interesting detail: his career threads together deep systems work and developer ergonomics, making him as fluent in enterprise integration as in developer APIs.
