• Provide reference solutions demonstrating correct approaches.

• Identify and flag ambiguous or unverifiable tasks.

REQUIRED QUALIFICATIONS

• Strong hands-on experience in at least one of Python, Java, Rust, Go, C++, or TypeScript.

• Deep understanding of algorithms, data structures, and software engineering principles.

• Proven ability to debug complex systems and optimize software performance.

• Experience with feature development, codebase refactoring, or legacy system modernization.

• Strong technical documentation and communication skills.

ENGAGEMENT DETAILS

• Approximately 15 hours per week with flexible scheduling.
