I'm in that boat except the ages are reversed and the older guys are constantly trying to build things from scratch. They just refuse to spend any time looking for off-the-shelf solutions and only build on what they know, so we waste time and end up with a crappy result.

Example: For a parallel data processing pipeline they wanted to build a REST interface for submitting "jobs" to a cluster which would parallelize with MPI, instead of just using xarray+dask.

Another example: They wanted to store tabular data product metadata Postgres with URIs pointing to NetCDF files on disk, instead of just putting everything inside NetCDF.
