Good question. I was in the process of testing out DokuWiki for internal documentation, that was really cool.

But probably using Tailscale to phase out our janky ipsec VPN solution. Super high speed and bandwidth aren't a concern at my current place, so Tailscale would be a great solution to fix the current setup we have and make remote work much easier for end users.

I was looking at a Grafana/Prometheus stack for active monitoring and metrics too, which would have been really cool.

I was also talking to the former owner about developing an in-house piece of software that used machine learning and OCR to pull relevant data out of huge construction PDFs, convert it to CSV formatted data, and import that directly into our estimating software, saving our estimators massive amounts of time having to manually parse those documents and input the data line by line, cell by cell.
