Yeah, either that or "architecting something new looks better on my resume than using an existing solution."

Do you have "implemented a task scheduler" on your resume?

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.
