Senior software engineer building healthcare, observability, and AI-powered platforms at scale.
United StatesWhat I'm looking for
I’m a Senior Software Engineer with 12 years of experience building healthcare, observability, and global marketplace platforms at Amazon, Datadog, and Airbnb. I lead end-to-end delivery across cloud-native microservices, AI-powered workflows, and high-scale distributed systems.
At Amazon (Amazon One Medical), I expanded telehealth capabilities by launching Amazon Clinic and building HIPAA-compliant microservices for intake, provider matching, visits, and prescriptions integrated with EHR using FHIR. I owned backend orchestration with event-driven asynchronous processing to stabilize high-volume workflows, improve reliability under peak load, and cut failed requests.
I also strengthened performance and AI productivity by optimizing APIs (reducing latency 30%) and building AI-powered patient summarization and triage support (reducing manual review effort 30%). Earlier at Datadog and Airbnb, I delivered reliability and modernization—defining SLIs/SLOs and incident response at Datadog, and improving booking experiences and conversion through server-side rendering and migration from legacy systems at Airbnb.
Experience
Work history, roles, and key accomplishments
Led expansion of Amazon One Medical telehealth and clinical workflows, building HIPAA-compliant microservices (intake, provider matching, visits, prescriptions) integrated with EHR via FHIR, supporting millions of patients. Improved reliability and performance by making intake/visit orchestration event-driven, reducing failed requests under peak load, cutting latency 30% via caching/query tuning,
Owned reliability of telemetry ingestion and alerting pipelines across thousands of services, designing Kafka-based ingestion, normalization, and ETL flows to handle backpressure, retries, and uneven traffic. Defined SLIs/SLOs and drove incident response, reducing repeat production issues by 40% and scaling ingestion/storage infrastructure on Kubernetes and GCP/AWS.
Contributed to global booking and listing platforms, implementing server-side rendered React flows that reduced initial load time by 25% and improved booking conversion by 5% through faster search-to-checkout experiences. Built and hardened microservices for reservation and payment, adding retries and idempotent endpoints that reduced peak booking errors by 20% and refactoring legacy components to
