  • Refactor and modernize legacy functionality without unnecessarily introducing risk to existing applications
  • Understand the differences between traditional monolithic .NET architectures and modern distributed/cloud-based architectures
  • Develop clean, maintainable, testable, and reusable code
  • Participate in code reviews and contribute to engineering standards and best practices
• API & Microservices Architecture
  • Design and develop RESTful APIs and microservice-based solutions using modern .NET technologies
  • Understand API contracts, versioning, authentication, authorization, error handling, logging, and service-to-service communication
  • Understand the principles and tradeoffs associated with monolithic versus microservice architectures
  • Build services that can be independently developed, tested, deployed, and scaled where appropriate
  • Understand asynchronous processing, messaging, and event-driven patterns

  • Develop and maintain data access layers using EF Core
  • Understand Code First, database migrations, LINQ, relationships, transactions, and change tracking
  • Diagnose and optimize database queries and application performance
  • Experience working with SQL Server and relational database concepts

  • Support and collaborate with teams across design, development, quality assurance, and operations
