...points I have in mind • The conversion must run unattended once configured, ideally accepting a date/time or file list and processing in batch. • Output .gem files should preserve the full MRMS metadata so they open seamlessly in GEMPAK analysis tools. • Documentation (read-me or inline comments) must explain every dependency, command, and option so I can reproduce the workflow on my own Linux machine. • Efficiency counts: downloading only the needed tiles or using on-the-fly streaming is a plus, but clarity and reliability are more important than micro-optimisations. If you have prior experience wrangling MRMS, GEMPAK, or large AWS S3 datasets, I’d love to see a brief outline of how you would tackle the problem along with an estimated timeline....

My website is running smoothly on a Linux server with Apache, but I now have a Windows-based environment waiting and need everything moved across to IIS without a hiccup. The job covers both the site files and a MySQL database, so the full stack has to come over intact, re-configured, and fully tested on the new server. The Windows machine is already provisioned; what’s missing is the clean transfer, IIS setup, and any tweaks to connection strings so the application recognises the MySQL instance on Windows (or an alternative you recommend if it streamlines performance). I want the migration handled with minimal downtime, SSL preserved, and URL structure unchanged so search rankings remain stable. Deliverables • Complete copy of all website files placed in the corr...
