  • Integration & Ecosystem: Define approaches to integrate modernized applications with enterprise ecosystems (APIs, event-driven architecture, cloud).
  • Proof of Concepts (POCs): Drive R&D pilots to validate GenAIs effectiveness in accelerating modernization and reducing manual rework.
  • Governance & Compliance: Ensure transformation solutions adhere to security, compliance, and audit standards for enterprise environments.
  • Collaboration: Work closely with business stakeholders, modernization teams, and AI/ML experts to align solutions with enterprise IT roadmaps.
  • Mentorship & Knowledge Sharing: Provide guidance to development teams on legacy code patterns, modernization practices, and GenAI adoption.
