I took horrible basically no documentation globally scoped spaghetti code in perl, with a proprietary db based on flat files and forking web scraper from the 90s, which used n ancient form of ipc that predated posix and mostly didn't run, and rewrote, debugged, unit tested and updated it so it runs, faster and better than before. I built a new front end using dancer (perl framework kinda like Sinatra) with a nginx reverse proxy to replace the cgi scripts originally used.
