About us:

Nyros is a Web & Mobile apps development agency with a global team of designers, developers and managers. Our goal is to expand opportunities for anyone to imagine, design, and make a better world.


Position Summary:

We are seeking an experienced .NET Developer to lead the migration of a large-scale ASP.NET C# 4.0 Web Forms application into a modern ASP.NET Core MVC architecture. The ideal candidate should have a strong background in legacy .NET Framework applications, deep knowledge of modern .NET Core, and experience in designing scalable, maintainable, and secure enterprise applications with a modern user interface.


Key Responsibilities:

  • Analyze the existing 

    ASP.NET Web Forms application (C# 4.0)

     to understand functionality, dependencies, and architecture.
  • Plan and execute the 

    migration strategy

     from Web Forms to ASP.NET Core MVC.
  • Redesign application components following 

    modern software design patterns (MVC, Repository, Dependency Injection, etc.)

    .
  • Migrate data access layer from 

    ADO.NET/legacy ORM

     to 

    Entity Framework Core

     or another modern ORM.
  • Modernize the 

    UI/UX

     using 

    Razor Pages, Blazor, or integration with front-end frameworks (React/Angular/Vue)

     as required.
  • Ensure 

    cross-platform compatibility

     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).

  • 5+ years of experience

     in .NET development.
  • Strong knowledge of 

    C#, ASP.NET Web Forms (4.0/4.5)

    , and legacy .NET Framework applications.
  • Proven experience in 

    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 

    Azure DevOps, Git, CI/CD pipelines, Docker, and Kubernetes

    .
  • Strong understanding of 

    application security best practices (OWASP, identity management, OAuth, JWT, etc.)

    .
  • Excellent problem-solving skills, attention to detail, and ability to work independently.


Nice-to-Have Skills:

  • Experience in 

    Blazor

     or 

    MAUI

     for modernizing UI further.
  • Knowledge of 

    cloud-native application design

     (Azure/AWS).
  • Familiarity with 

    message queues (RabbitMQ, Kafka)

    .
  • Prior experience in 

    application modernization projects
