Deployed microservices to Cloud Foundry via Jenkins pipeline* MPS - Planned Satisfaction Message processingArchitected, designed, and implemented a microservice to mirror an opaque third-party database and provide an interface for querying the data for further reporting. This was implemented using Kafka Streams for processing incoming update notification events, querying the third-party service for the detailed updates, and applying the deltas to an in-memory datastore. Included robust fault recovery and restart logic.* MPS - Mission AwarenessArchitected and designed a set of microservices to gather Mission Awareness data from other microservices, collate it, and deliver files to client AWS S3 buckets with file delivery notifications being sent via REST API calls. The system was implemented as a pair of microservices, a dispatcher/coordinator microservice, and an executor microservice that could be easily scaled out as additional spacecraft were brought online. Used Kafka Streams to coordinate the delivery and notification processing.* MPS - Groundtrack and Off-Nadir GeneratorArchitected, designed, and implemented a microservice to gather data from other microservices, collate it, and create Shapefiles to be delivered to client AWS S3 bucket.
