A fully-working custom CRM + ERP developed in PHP on top of the Laravel framework (at admin.eurotechnik.gr). Deployed on an initially unmanaged dedicated server. The latest addition was the automated bid-creation subsystem that uses AI for prediction of customer demand and supply shortages.View Project
Ad-hoc peer-to-peer wireless communications using Raspberry Pi's
The setup consists of a number of wifi-capable Raspberry Pi Zero's each of which may bound its TCP sockets to a specified IP address with the student's number (SSN) as the last digits. On each of them runs the same app that on initialization creates three POSIX threads, one to listen for inbound connection requests (server thread) one to search via polling for other active devices in wireless range, and the 3rd which produces a message with a random recipient at a random interval.
When devices connect, they exchange messages. A device sends to the other device all the messages not intended for it and receives the corresponding messages from the other device. The purpose is for a message to reach its recipient after zero or more intermediate recipients. The final recipient stores its messages in an internal inbox (in memory).
