I'm part of the Data Platform team at VAY where I was mainly responsible for building, maintaining, and fixing issues of ingestion pipelines for batch and streaming telemetry data that would come from VAY autonomous vehicle fleet. The Ingested data was then made available to be queried over an SQL interface by the stakeholders.
