We are seeking an experienced .NET Web Developer to design, develop, test, and deploy enterprise-grade web applications. You will be responsible for building scalable, maintainable solutions using the .NET ecosystem, implementing modern design patterns, and integrating with various third-party services while ensuring code quality through comprehensive testing and automated deployment pipelines.

Key Responsibilities

1.Application Development

• Design and develop scalable web applications using ASP.NET Core / ASP.NET MVC
• Build and maintain RESTful APIs and microservices architectures
• Develop responsive front-end interfaces using modern frameworks (Blazor, React, Angular, or Vue.js with .NET backend)
• Write clean, maintainable, and well-documented code following SOLID principles
• Optimize application performance and database query efficiency
• Implement proper separation of concerns and layered architecture

2.Architecture & Design Patterns

• Implement industry-standard design patterns:
  • Repository Pattern: Abstract data access logic from business logic
  • Unit of Work Pattern: Manage database transactions across multiple repositories
  • Dependency Injection: Promote loose coupling and testability
  • Factory Pattern: Create objects without specifying exact classes
  • Strategy Pattern: Define family of algorithms and make them interchangeable
  • CQRS Pattern: Separate read and write operations for complex domains
• Apply clean architecture principles and domain-driven design (DDD) concepts
• Design event-driven architectures for scalable systems
• Implement caching strategies (in-memory, distributed) for performance optimization

3.Testing & Quality Assurance

• Write comprehensive unit tests using xUnit, NUnit, or MSTest
• Implement integration tests for APIs, services, and database operations
• Use mocking frameworks (Moq, NSubstitute) for isolated unit testing
• Develop automated test suites and maintain minimum test coverage standards
• Perform code reviews and ensure adherence to coding standards and best practices
• Debug and resolve application issues across different environments
• Implement test-driven development (TDD) practices where applicable

4.API Development & Integration

• Design and build RESTful APIs following OpenAPI/Swagger specifications
• Implement proper API versioning strategies
• Handle authentication and authorization (OAuth 2.0, JWT, Identity Server)
• Develop GraphQL APIs when appropriate
• Integrate third-party APIs and services:
  • Payment gateways (Stripe, PayPal, Razorpay, Square)
  • Authentication providers (Auth0, Okta, Azure AD)
  • Communication services (Twilio, SendGrid, Mailgun)
  • Cloud storage (AWS S3, Azure Blob Storage)
  • SaaS platforms (Salesforce, HubSpot, Shopify)
• Implement webhook handlers and event-driven integrations
• Manage API rate limiting, throttling, and retry logic
• Handle API documentation and client SDK generation

5.Background Jobs & Queue Management

• Design and implement background job processing using:
  • Hangfire: Schedule recurring jobs and process background tasks
  • Quartz.NET: Build enterprise job scheduling solutions
  • Azure Functions: Implement serverless background processing
• Develop message queue solutions with:
  • RabbitMQ: Implement reliable message-based communication
  • Azure Service Bus: Build cloud-native messaging solutions
  • AWS SQS/SNS: Develop distributed queue systems
• Implement proper error handling, retry logic, and dead-letter queue management
• Schedule and monitor recurring jobs, batch processes, and long-running tasks
• Optimize queue throughput and handle message prioritization
• Implement idempotent message processing

6.Deployment & Configuration Management

• Deploy applications to cloud platforms (Azure, AWS) and on-premise servers
• Configure and maintain CI/CD pipelines using:Azure DevOps (Azure Pipelines),GitHub Actions,Jenkins,GitLab CI
• Manage application configuration across multiple environments (Development, Staging, Production)
• Implement configuration best practices:
  • Environment-specific appsettings.json files
  • Environment variables and secrets management
  • Azure Key Vault or AWS Secrets Manager integration
  • Feature flags and configuration toggles
• Implement containerization using Docker
• Deploy and orchestrate containers using Kubernetes or Docker Swarm
• Set up application monitoring and logging (Application Insights, Serilog, ELK stack
• Handle blue-green deployments and canary releases
• Manage database migrations and schema versioning (Entity Framework Migrations, FluentMigrator)
