About Krishan Kumar

I thrive at the intersection of complex legacy systems and the future of Cloud-Native AI. With over 18 years of experience, I’ve specialized in taking mission-critical, high-stakes platforms—the kind that cannot afford a single minute of downtime—and modernizing them for the next generation of business. At NM I am leading the architectural shift for data, decision & information tracks for our Claims Benefit platform, transforming it into a \"One-Stop Shop\" for Life, Disability, and Long-Term Care insurance. This isn\'t just about moving code to the cloud; it’s about reimagining the entire business process. With Active-Active database architectures and continuous data replication from IBM Mainframe (DB2) to AWS Aurora, we’ve kept our digital transformation invisible to users while delivering real business value. What excites me right now? The fusion of AI and Architectural Engineering.I am currently leveraging GitHub Copilot, Prompt Engineering, and AI Agents not just to write code, but to reverse-engineer decades of legacy business logic. By developing custom AI prompts that generate production-ready Spring Boot and NodeJS microservices from OpenAPI specs, I’m helping my teams move faster while maintaining the highest engineering standards.My Core Focus Areas:Modernization: Orchestrating the move from Mainframe/Oracle/SQL to AWS (RDS, S3, DynamoDB) without service interruption.Architecture: Designing Event-Driven systems (Kafka/EventBridge) and Serverless workflows (Lambda) that drive Straight-Through Processing (STP).Team Leadership: Leading diverse, multi-vendor engineering teams to deliver high-quality, scalable solutions through mentorship and clear technical roadmaps.Digital Experience: Integrating eSignatures, Claim Preferences integration with client website, making claim decisions, Integration with various NM systems, Claim Kit processing, Provider and claim contact management, policy exclusions, and client interview to reduce manual overhead.I’m always looking to connect with fellow architects, engineers, and leaders who are passionate about the future of InsurTech, AWS Cloud, and Generative AI.
