• Define and own the modernization roadmap from current .NET to the latest .NET (Core / .NET 8+) stack
• Design and implement a microservices-based architecture using modern design patterns
• Lead the migration to AWS Cloud, defining cloud-native architectures and best practices
• Establish standards for API design, service communication, security, and observability
• Guide teams on strangler, re-platforming, and re-engineering strategies
• Work closely with product owners, business stakeholders, and engineering teams
• Review and approve architecture designs, code standards, and technical implementations
• Ensure scalability, performance, resiliency, and cost optimization in the target architecture
• Mentor senior and mid-level engineers on cloud and microservices best practices
• Drive governance, risk mitigation, and technical decision-making across the program
