* Co-designed, security reviewed, coded, instrumented, tested, and conducted a live roll-out of an Amazon Prime SOA service that needed replacing. Implemented a continuous delivery pipeline for the service, using existing Amazon tools, unit tests (JUnit, Mockito), and integration tests. Created the new DynamoDB storage model to better implement the old service's MySQL model.* Designed, coded, implemented, and tested replacement code for hard-coded business logic within a "live", high TPS production service. Conferred with and arbitrated between business logic stakeholders, documented possible usage scenarios, continuously communicated with stakeholders to keep design relevant to their use case. Leveraged Spring and Java 8 features to increase code modularity and flexibility, and leveraged existing Amazon libraries to massively increase configurability.* Monitored and performed "on-call" duties for our existing Amazon Prime SOA services. Monitored normal and extreme use cases of services, revised service alarm conditions based on usage, and trouble-shot late night high severity alarm conditions. Trouble-shot trouble tickets cut to the Prime Membership team, performed customer service operations to clear customer problems, and designed, proposed, created and launched changes to existing services to fix reoccurring customer service problems.* Created new tools for stress testing Prime services ("HammerTime"). Created tools in Ruby and AWK for performing maintenance duties on services and data bases, and for more easily parsing service logs generated by live services.
