Started using PERL at NASA/Langley back in 1989 or 1990. Probably haven't gone two days without using it in some form, since.
I've created documents with it (CSV, XLS/XLSX, Postscript, PDF, text), connected to databases (MySQL/MariaDB, PostGres, SQL Server, SQLite), built a million web services with it (mostly back in day when CGI was the rage), created a ton of financial analysis applications with it, run it across Solaris, Windows, Linux (too many distros to even think about listing), and even old AIX systems.
There's little I haven't done with it. I'm happy to answer questions.
