A repository of 16 recent architectural deployments, detailing the engineering strategies used to solve complex healthcare data and infrastructure challenges.
Executed a zero-downtime migration of 2.4 million patient records from legacy Cerner instances to a centralized Epic Chronicles database using parallel dual-write pipelines.
Designed a federated GraphQL API layer to unify billing, scheduling, and clinical lab result microservices into a single graph for a high-performance React Native mobile app.
Engineered a globally distributed Selective Forwarding Unit (SFU) network to support multi-party telepsychiatry sessions with strict E2EE and sub-50ms latency requirements.
Developed a real-time parsing engine that intercepts legacy HL7 ORU (Observation Result) messages and transforms them into valid FHIR Observation and DiagnosticReport resources.
Implemented a zero-trust architecture across a 12-hospital network, deprecating VPNs in favor of cryptographic identity-based access proxies and immutable audit logging.
Migrated an on-premise SQL Server data warehouse to a Snowflake lakehouse architecture on AWS, accelerating population health query times by 400% while reducing infrastructure costs.
Trained and deployed a machine learning model analyzing real-time vital streams to predict early sepsis onset, integrated directly into the clinician's dashboard via REST API.
Built robust Apache Airflow DAGs to ingest, deduplicate, and normalize patient demographic data from 30+ disparate clinics into a central Health Information Exchange (HIE).
Centralized identity across a merged hospital system by federating three legacy Active Directory forests into a unified Okta tenant, enabling secure SSO for 8,000+ staff.
Utilized the Strangler Fig pattern to systematically decouple a 15-year-old billing application into Go-based microservices orchestrated by Kubernetes.
Developed an accessible, WCAG 2.1 AA compliant Next.js portal for expectant mothers, integrating directly with Cerner Millennium via SMART on FHIR protocols.
Engineered a high-throughput gRPC ingest gateway to process millions of concurrent vitals readings from at-home medical devices, writing directly to Apache Kafka.
Designed a petabyte-scale secure Data Lake on GCP for storing anonymized MRI/CT scans, utilizing Cloud Healthcare API for intelligent de-identification.
Implemented an XGBoost model that intercepts outbound billing claims, predicting likelihood of denial and suggesting corrective coding actions in real-time.
Architected fault-tolerant daily batch ETL jobs to securely extract, encrypt, and upload millions of immunization records to state DOH registries via SFTP.
Designed an immutable, air-gapped backup strategy for critical clinical databases, ensuring point-in-time recovery capabilities in the event of ransomware attacks.
