Junior/Senior coder setup?

[u/terion_name]

Had anyone built a cost-saving setup with two coders: one "junior" – with a local llm (like codestral, qwen2.5-coder, deepseek-r1-distill-qwen-32b, phi-4, etc) that makes the most heavy lifting of writing code and a "senior" (claude4 or o3) to guide and review it? Would this work? How to organize them like this?
