• Disambiguated requirements for data synchronization and compliance to support EHR integration. Worked with stakeholders to deep dive into clinical workflows and use cases, propose new UX flows, and design technical.
• Created high level designs for two integration deliverables – Encounter Creation and Order Ingestion. These designs introduced foundational components for consuming events of clinical data changed in the EHR and for.
• Proposed new data modeling for clinical data storage to decouple unique documentation use cases and to enable independent state management of clinical data entities.
• Became certified as an AWS Security Guardian. Oversaw security reviews and GEAR compliance reviews for a new event-based architecture that would enable Identity data to be synchronized across differently-optimized.
• Implemented and launched a workflow improvement which relied on DDB snapshot functionality rather than table scans to send data to the Anti-Entropy system, allowing the data to be compared daily rather than weekly.
• Investigated and root-caused a propagation delay seen in the event bus architecture. Proposed a new integration method relying on Kinesis Data Streams and prototyped this solution, observing a 95% reduction in latency.

• Designed an identity and access management system for Amazon Care, including onboarding processes, login and authentication flows for two user populations (customers and clinicians), and custom authorization based on.
• Proposed federating from an external identity provider as a way to consolidate identities for clinicians. Convinced leadership this was important in order to support access to 3rd party systems, simplify identity.
• Drove a team-wide initiative to reduce API latencies, including investment in eager initialization, building orchestration layers, supporting pagination and batching, and adding token claims to reduce network calls..

• Launched new architecture in air-gapped region, achieving parity for 5 systems after 2+ years.
• Drove a project to automate regression testing and improve deployment processes. Designed pipeline validation tests using known scenarios and mocking dependency calls. Worked with team to automated CM validations and.
• Produced a vision document outlining architectural considerations and categorizing current and proposed pricing models in generic ways in order to improve flexibility and reduce time to market.
• Created high level design for a new system to consume events regarding organizational changes and store a representation of account structures for billing. This decouples accounts and computation and enables.
• Facilitated several cross organization projects including redesigning the recurring fee experience (impacted Marketplace, Sentinel, and AWS Support), exposing Unbilled Usage (worked with DW) and amortizing support.

• Worked with several senior engineers and a principal to redefine the way contracts are represented within computation systems. This involved changing the data model to preserve the raw data for auditability and better.
• Designed and implemented a new checksum-based auditor that ran inline during bill generation, enabling deprecation of the previous batch-driven auditor. Removed dependency on legacy MySQL database and reduced bill run.

• Worked on the design, development, and maintenance of large-scale backend systems used for bill computation in AWS (handling up to 40,000 tps and 16% month over month growth rate).
• Designed, implemented, and launched a rearchitected pipeline to decouple and independently scale processing components and move to an event driven computation system. Reduced latency by 44%.
• Led the planning effort for the bill run process after launch. This involved evaluating the auditing story, developing tools to verify completeness, defining new SLAs, and determining the schedule.
• Devised and drove the delivery of 3 security goals in 2014 to help reduce vulnerabilities in all environments. Became a bar raiser in my organization to improve the quality of deployments. Led the effort to.
