Personally I'd see it as a negative vs using an industry standard solution.
However, I'm sure some folks would be tempted to add something like "designed and implemented a distributed task scheduler and execution engine for generalized asynchronous jobs utilized by X number of devs across Y teams" to their resumes.
My question is on the line of do you think it's relevant enough so that it would deserve being added to a resume? Even if it's something you personally don't like.
Because I can't imagine why it would award that relevance. It's right there with "implemented function to reverse a list because the stdlib had a bug".
