Job Title:.Net Developer

Location: Remote Duration: 12+ Months Rate: $50/hr W2 - $55/hr W2 or $65/hr C2C

Job Description: Core skill- Expertise in System.Linq.Expressions:

Candidate must move beyond "using" LINQ to "building" it. Need deep experience manually constructing and modifying Expression Trees (using ExpressionVisitor) to rewrite queries at runtime. We need somebody who can build the engine to run the application and not just use the engine. I don't see any LINQ or Entity Framework expertise. We need this core expertise otherwise they will not be suitable.

• .NET App development with Entity Framework and LINQ skills
• Expertise in System.Linq.Expressions: They must move beyond "using" LINQ to "building" it. They need deep experience manually constructing and modifying Expression Trees (using ExpressionVisitor) to rewrite queries at runtime.
• EF Core Internals & SQL Translation: Deep understanding of the Entity Framework Core translation pipeline. They should know how to troubleshoot "could not be translated" errors by restructuring C# logic into SQL-compatible structures (like Joins and Projections).
• Advanced Metaprogramming: Proficiency in Runtime Type Generation. They should be comfortable creating dynamic types at execution time to handle varying data shapes without causing memory leaks.
• Architectural Pattern Mastery: Advanced experience with the Builder Pattern and Fluent API Design (similar to how the EF Core "Fluent API" itself is built).
• Functional Programming in C#: High comfort level with generics, delegates, and higher-order functions (passing logic as data).
