• Use AutoMapper and other supporting libraries/frameworks to implement efficient application-layer and data-layer transformations.
  
• Containerize applications and services using Docker and support deployment within cloud-based environments.
  
• Implement appropriate application logging, monitoring, and error tracking using tools such as Sentry and Azure Application Insights.
  
• Troubleshoot and debug application, API, database, integration, and production issues.
  
• Conduct code reviews and follow established coding standards, development practices, and security guidelines.
  
• Collaborate with QA teams to investigate defects, resolve issues, and support successful application releases.
  
• Participate in Agile/Scrum ceremonies, including sprint planning, refinement, estimation, daily stand-ups, reviews, and retrospectives.
  
• Provide technical inputs during requirement analysis, solution discussions, effort estimation, and implementation planning.
  

• Strong hands-on experience in C#, .NET 6+ and ASP.NET Core.
  
• Good experience in REST API development, backend integration, and service-oriented application development.
  
• Strong understanding of JWT authentication, authorization, and service-to-service authentication.
  
• Practical knowledge of Microservices Architecture and Event-Driven Architecture.
  
• Hands-on experience with Azure fundamentals and Azure Service Bus, including Queues, Topics, and DLQ.

What We Expect:

• Strong problem-solving and analytical skills with a focus on developing reliable and scalable backend solutions.
  
• Good understanding of software development lifecycle and backend application architecture.
  
• Strong attention to code quality, security, performance, and maintainability.
  
• Ability to independently troubleshoot technical issues and identify appropriate solutions.
  
• Strong ownership and follow-through from development through deployment and production support.
  
• Effective written and verbal communication skills.
  
• Ability to work collaboratively with cross-functional teams in a fast-paced environment.
