Data Analytics Pipeline
Architected an analytics aggregation pipeline using BigQuery, Google Pub/Sub, and Google Dataflow. Data from multiple microservices were published to Pub/Sub, from where it was pushed to Google Dataflow. It gets processed and transformed there and streamed into BigQuery. From BigQuery, aggregated data is exposed to the front end using an endpoint created by an analytics microservice.
