Outsourced - Senior Software Engineer Experian Employee Review

Management began to make moves to remove my employment. Performance was hyper focused on negative despite achievements. I sought assistance from HR and upper management, they in turn told my manager to develop a PIP. PIP set a list of tasks to be graded on at the end of review. All seemed well on the graded tasks when manager began to rattle off other concerns outside the PIP. Terminated based on performance. Contended and showed emails of timelines and deliverables, doesn't help. Discovered three weeks later that my position is being posted in Costa Rica with a higher skill set ( likely could not hire someone in the US for what they were paying me with that level of skill )
