Ranjith Rajasekharan is a Senior Technology Leader and Data Infrastructure Architect renowned for transforming how global enterprises modernize, secure, and scale their mission-critical data systems. With nearly two decades of experience across healthcare, banking, and telecommunications, Ranjith has built a legacy of delivering high-impact, AI-enabled modernization programs that strengthen enterprise resilience and data integrity at scale.
As Lead Data and Cloud Architect at Cognizant Technology Solutions US Corp, Ranjith leads the modernization and governance of cloud-native data platforms supporting over 1.8 million health-insurance members and 60,000 healthcare providers across the United States. His leadership in designing and executing the Enterprise Data Modernization and AI-Driven Analytics Platform has set a new industry benchmark for intelligent healthcare operations. The initiative achieved a 70% improvement in data-pipeline performance, boosted system uptime from 92% to 99.9%, and reduced infrastructure costs by 35%. His AI-based fraud detection models improved accuracy by 25%, preventing $8–$10 million in annual losses while enabling near real-time analytics across millions of healthcare transactions.
Ranjith’s innovations have redefined data engineering and automation. As Lead Oracle Cloud Engineer, he developed an AI-driven automation framework that predicts workloads, optimizes Exadata configurations, and orchestrates end-to-end database migrations with near-zero downtime. This solution delivered 3× faster transaction performance and 40% lower operational costs, earning recognition in Oracle’s Internal Innovation Showcase as a model for global enterprise modernization. Portions of this automation framework were later open-sourced, empowering engineers worldwide to adopt AI-based optimization in cloud environments.
A recognized expert in disaster recovery and business continuity, Ranjith spearheaded the Enterprise Resilience Initiative, aligning corporate recovery practices with ISO 22301, NIST SP 800-34, and SOC 2 standards. By automating failover orchestration and backup validation, he reduced recovery time by 60% and protected more than $2 million per year in potential revenue loss. His methodologies have since been adopted enterprise-wide as the benchmark for business continuity planning and readiness.
Ranjith’s work carries direct national-interest significance, particularly in advancing U.S. healthcare data integrity, cybersecurity, and AI-enabled fraud prevention. His frameworks ensure continuous compliance with HIPAA, SOC 2, and other key regulatory standards—protecting critical data infrastructures that millions rely on daily. Through the fusion of AI automation, cloud reliability, and ethical engineering, Ranjith’s contributions continue to support the nation’s mission for secure, reliable, and future-ready healthcare systems.
He holds a Master’s degree in Information Technology and a Bachelor’s degree in Software Systems, along with premier industry certifications including Oracle Cloud Infrastructure Architect, Oracle Autonomous Database Specialist, AWS Solutions Architect, and Microsoft Azure Certified Engineer.
With a proven record of delivering transformative results, Ranjith Rajasekharan stands among the top global leaders in data architecture and cloud innovation. His visionary leadership, AI-driven automation frameworks, and resilience-focused design principles continue to reshape enterprise modernization, strengthen national digital infrastructure, and drive global excellence in data engineering and cloud transformation.
