Chosen criteria based on my professional experience
Rajesh has led the design and delivery of enterprise-scale security services at Oracle and Zscaler, including SCIM-based provisioning, contextual access platforms, and distributed identity services. His responsibilities have included defining architecture roadmaps, embedding OWASP practices, and ensuring compliance across mission-critical platforms.
Rajesh has mentored more than dozen engineers over two years, many of whom have progressed into senior and staff engineering roles. He developed structured learning paths, organized study circles on cloud-native security, and guided engineers in delivering large-scale projects such as IDCS tenant migration and Zscaler’s contextual access platform. His mentorship has fostered a sustainable culture of coaching and professional growth.
Rajesh has advised internal teams, global security engineering units, and academic institutions on secure systems design. He has supported curriculum development for cybersecurity modules and contributed to industry panels and awards programs. His consultancy work emphasizes aligning modern identity protocols (SAML, OAuth, OIDC, SCIM) with enterprise requirements for resilience and scalability.
