Final Project: Social Media Blog API

Project Overview
This social media application was an API backend without a frontend. The app had the ability to manage user accounts and messages that they submit to the application. Users were able to see all of the messages posted to the site as well as the messages posted by a particular user. In either case, we require a backend which is able to deliver the data needed to display this information as well as process actions like logins, registrations, message creations, message updates, and message deletions.

Technologies used: Java, Javalin and JDBC
Assessment status: Passed

•  Monitoring IN nodes/servers (AIR, CCN, SDP, OCC, etc.) network traffic.
  i. . Detecting active alarms (critical, major, moderate and minor) using Monitoring tool (MITO) on time
  and try to fix it.
  ii. . Perform escalation of incidents to higher tier support groups, vendors, and other support staff based on NOC process when unable to resolve the incident.
