At Robinhood, I designed and implemented a web interface that enables engineers to troubleshoot and reprocess errors in Kafka consumers gracefully, now used by 3 Robinhood internal services. The interface allows engineers to debug failure case and apply operations such as skipping or republishing, for each individual issue or in bulk, creating a significant reduction in on-call engineer burden. I developed the application using React frontend, Python and Django backend, and custom Robinhood Kafka libraries.
