     and deployment readiness on 

    Windows/Linux cloud environments (Azure, AWS, or on-premises)

    .
  • Optimize application performance, security, and scalability during migration.
  • Write 

    unit tests, integration tests, and automated deployment scripts

     to ensure code quality.
  • Collaborate with QA, DevOps, and design teams to deliver a seamless migration.
  • Provide 

    documentation and training

     to internal teams for post-migration maintenance.


Required Skills & Qualifications:

  • Bachelor’s degree in Computer Science, Engineering, or related field (or equivalent experience).

    ASP.NET Core (5/6/7/8) MVC

     and related technologies.
  • Proficiency with 

    Entity Framework Core, LINQ, SQL Server

    , and database migration strategies.
  • Experience with 

    front-end frameworks (Bootstrap, jQuery, React, Angular, or Vue)

     for modern UI design.
  • Hands-on experience with 

    REST APIs, JSON, Web API migration

    , and microservices architecture.
  • Knowledge of 

    dependency injection, middleware, logging, and configuration management

     in ASP.NET Core.
  • Familiarity with
