Key Responsibilities

• Re-architect existing systems or codebases independently using transition architecture principles.
• Lead incremental decomposition of monolithic applications into microservices, including service boundaries, data contracts and migration sequencing.
• Design, implement, monitor and debug .NET/C# backend services across the full lifecycle through production observability.
• Build and extend Entity Framework services, managing schema migrations, query optimization and ORM configuration across SQL Server and PostgreSQL.
• Author, review and maintain cloud infrastructure using Azure Bicep, ARM templates, Terraform or equivalent.
