Madankumar Pichamuthu developed the Azure Edge Integration Cell (EIC) Reference Architecture Documentation for the SAP/architecture-center repository, focusing on creating a clear and production-ready onboarding resource for architects. He established the initial directory structure, refined diagrams using Drawio, and ensured all image assets and references were consistent throughout the documentation. By updating deployment environment references from AWS to Azure and adding a High Availability section with visual explanations, Madankumar addressed key technical requirements for Azure adoption. His work, delivered in Markdown and supported by strong technical writing and diagramming skills, provided a solid foundation for future documentation and accelerated project readiness.
