I have been in a similar position. In case you stopped receiving your salary, you should bail immediately. If you are being paid, start preparing to jump ship while continuing to work.

We had a similar problem building an ad network. We ended up logging events into a HDFS using Kafka. Backend for serving was built using Java (Go Seems fine too). As for serving reports in real time, I don’t think that would be doable. We need up refreshing the reports every 30 minutes. Building these analytics views can be accomplished using Cassandra, Hive or ElephantDB or any other. People have used apache storm also. You can look up the book Big Data principles by Nathan Marz for discussions on scalable architecture.

Disclosure: I did not code this. I only participated in architecture reviews.

Polymorphism on the other hand is a powerful technique to build flexible systems.
