5) Implement messaging solutions using RabbitMQ or Kafka (publish/subscribe, dead-letter queues, retry policies).

6) Apply Redis caching strategies to optimize system performance and reduce latency.

7) Collaborate with frontend developers by providing APIs and handling light JavaScript-based interactions.

8) Ensure code quality through best practices, unit testing, and design patterns.

Core Skills (Must-Have)

1) .NET Core (6.0+): Proficiency in ASP.NET Core (Web API, MVC, Middleware, Dependency Injection).

2) Entity Framework Core: Strong knowledge in data modeling and performance optimization.

3) Databases: SQL Server (complex queries, stored procedures, indexing) and MongoDB (document modeling, aggregation pipelines).

4) API Development: RESTful APIs, OAuth2, GraphQL, gRPC, Swagger, JWT.

5) Messaging Systems: RabbitMQ / Kafka with asynchronous processing patterns.

6) Caching: Redis (distributed caching, cache penetration/snowballing handling).

7) Basic JavaScript for frontend collaboration (Ajax, DOM manipulation).

Preferred Experience

1) Experience with ABP Framework (ABP Boilerplate / ABP.IO), including modular development and multi-tenancy.

2) Familiarity with ASP.NET Zero for customizing enterprise projects (permissions, UI extensions).

3) Exposure to cloud platforms (Azure/AWS) and CI/CD pipelines.

Soft Skills

1) Strong problem-solving ability with an analytical mindset.

2) Excellent communication and collaboration skills in Agile/Scrum teams.

3) Ability to mentor junior developers and guide code reviews.

4) Self-driven with a commitment to writing clean, maintainable, and scalable code.

Qualifications
