It enabled business developers to perform complete life cycle of workflow management, i.e. authoring, validating, visualizing, and version management ○ Aligned several business stakeholders to agree on MMS design by delivering deep-dive analysis of the workflow lifecycle management and a comprehensive list of MMS use cases. ○ Collaborated with several other Uber engineering teams as dependencies for MMS. ○ Integrated Orchestrator with MMS and enabled end-to-end testing, dynamic deployment, modular functionality to reduce execution development time by 50 %. ○ Ensured system reliability and availability by providing 99.5% test coverage, leveraging automatic testing, manual testing, dynamic metrics, monitoring and alerting. ○ Prepared and executed roadmaps in the absence of a Product Manager and successfully delivered MMS on time. ● Acted as the technical POC for Orchestrator. ○ Created a step-by-step instruction of Orchestrator, which has 1000+ views in UberEng. ○ Provided timely response across multiple channels like message channel, email, stackoverflow. ○ Created On-call rotations to ensure Orchestrator’s liability and quality. ### Full Stack Software Engineer @ Hack
