Sr. Backend Engineer

🌟 Practice Management Engineering Team

Worked on the Practice Management engineering team to transition from legacy technology to a modern, microservice-oriented architecture. This project replaced an outdated in-house EHR (Electronic Health Record) with a third-party system, enabling integration and greater flexibility for future innovation.

• Developed and maintained Golang microservices to streamline practitioner management, scheduling/availability, and data synchronization between legacy systems and the EHR.
• Implemented Temporal workflows to manage complex interactions with 3rd-party EHR such as appointment booking, patient creation, and on-demand routing. Workflows were often hooked into Kafka events to trigger as a result of new messages on the queue. Additionally, leveraged the actor pattern for durable execution and visibility into on-demand routing logic.
• Implemented gRPC endpoints for appointment booking, practitioner scheduling/availability, and data synchronization, enabling efficient and scalable inter-service communication.
• Debugged and resolved a critical routing issue where status was being overwritten, enabling stable call routing in preparation for our production launch.
• Monitored and analyzed endpoint latency using Prometheus and Grafana, ensuring acceptable performance while scaling practitioner availability systems from 200 to 1,500 providers.
• Collaborated with another team to assess scheduling endpoint performance, proposing and validating fallback strategies for scalability.
• Identified and resolved a critical department ID mismatch during on-call duties, unblocking practitioners and maintaining provider trust through direct follow-up.
• Migrated multiple backend services to Fx, simplifying dependency injection and improving system maintainability.
• Wrote acceptance tests for practitioner availability functionality, ensuring reliable and consistent operations.
• Used an in-house test harness to establish groundwork for on-demand routing acceptance tests, enabling future readiness despite current infrastructure limitations.
• Ensured high-quality unit testing, achieving an 80% test coverage threshold for key services. Used Mockery to create mocks when writing unit tests, ensuring robust and isolated testing of individual components.
• Maintained system health with OpsLevel, Dependabot, and Rollbar, reducing MTTR for critical production issues.

🚀 Clinical Engineering Team

Contributed to transforming clinical workflows and enhancing the provider and patient experience through innovative tools and efficient backend systems. Over six years, collaborated with cross-functional teams to deliver solutions that supported high-quality care delivery.

• Built and maintained tools using Python, Django, and Django Rest Framework, enabling providers to access and manage patient information efficiently.
• Developed automation workflows with Celery, including member health summaries integration for patient preparation and autocoding medications and allergies, significantly reducing manual overhead and ensuring data accuracy.
• Upgraded email communication systems from SendGrid to ExactTarget, improving reliability and scalability.
• Serialized clinical data snapshots into the database during chart sign-off, ensuring reliable and accurate historical record-keeping.
• Designed and implemented a full-stack Provider Payment Report Generation tool with Python/Django, HTML/CSS, JavaScript, and S3 Storage, automating financial reporting for providers.
• Led and contributed to the Chart Access project, enhancing provider accessibility to patient charts and supporting seamless care delivery:
  • Phase 1: Enabled provider access to patient charts regardless of appointment status, improving care continuity during emergencies, absences, or transitions.
  • Phase 2: Expanded Chart Access to care coordinators, improving their ability to assist providers and manage patient cases.
  • Phase 3: Scoped and planned the Unified Encounter Service, creating a foundation to unify legacy and video visit encounters under a single system with unique identifiers for all past and future visits.
  • Phase 4: Unimplemented, however, planned and scoped the association of all past and future Lab Orders, Radiology, and Prescriptions with the Unified Encounter, eliminating redundant references in the database and ensuring seamless integration across systems.
• Played a key role in reviving the Panel Management project, resolving critical performance issues:
  • Optimized backend filtering and data aggregation to enable care coordinators and providers to efficiently manage patient populations based on customizable criteria.
  • Salvaged the project’s initial strategy and implemented solutions to ensure a successful release.
• Enhanced Lab Order handling in alignment with CURES Act compliance, ensuring timely and automated release of lab reports:
  • Identified and resolved critical issues with lab report statuses, improving the accuracy of auto-release processes and ensuring compliance with federal requirements.
  • Collaborated with engineers to troubleshoot and optimize workflows, supporting providers with accurate and timely patient lab results.
• Supported junior engineers by providing guidance and sharing knowledge to foster their professional growth.
