PORTFOLIO_INDEX

Deployment Portfolio.

A repository of 16 recent architectural deployments, detailing the engineering strategies used to solve complex healthcare data and infrastructure challenges.

EHR Migration

Regional Network Epic Cutover

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.

Python Apache Kafka Epic Interconnect
API Integration

GraphQL Gateway for Patient Portal

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.

Node.js Apollo Federation AWS API Gateway
Telehealth Infra

Low-Latency WebRTC SFU Mesh

Engineered a globally distributed Selective Forwarding Unit (SFU) network to support multi-party telepsychiatry sessions with strict E2EE and sub-50ms latency requirements.

mediasoup WebRTC Redis
HL7 / FHIR

HL7 v2 to FHIR R4 Engine

Developed a real-time parsing engine that intercepts legacy HL7 ORU (Observation Result) messages and transforms them into valid FHIR Observation and DiagnosticReport resources.

Go HAPI FHIR Mirth Connect
Data Security

Zero-Trust Network Overlay

Implemented a zero-trust architecture across a 12-hospital network, deprecating VPNs in favor of cryptographic identity-based access proxies and immutable audit logging.

Cloudflare Access mTLS HashiCorp Vault
Cloud Warehousing

Clinical Data Lakehouse on AWS

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.

Snowflake dbt AWS S3
Predictive Analytics

Sepsis Onset Prediction Model

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.

PyTorch ONNX Feast
ETL Pipelines

HIE Data Aggregation Pipeline

Built robust Apache Airflow DAGs to ingest, deduplicate, and normalize patient demographic data from 30+ disparate clinics into a central Health Information Exchange (HIE).

Apache Airflow Python PostgreSQL
Identity Management

Enterprise Okta Federation

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.

Okta SAML 2.0 SCIM
Legacy Modernization

Monolith to Microservices Refactor

Utilized the Strangler Fig pattern to systematically decouple a 15-year-old billing application into Go-based microservices orchestrated by Kubernetes.

Kubernetes Go Kong API Gateway
Custom Portals

Next-Gen Maternity Care Portal

Developed an accessible, WCAG 2.1 AA compliant Next.js portal for expectant mothers, integrating directly with Cerner Millennium via SMART on FHIR protocols.

Next.js SMART on FHIR Tailwind CSS
API Integration

IoT Device Telemetry Gateway

Engineered a high-throughput gRPC ingest gateway to process millions of concurrent vitals readings from at-home medical devices, writing directly to Apache Kafka.

gRPC Apache Kafka Rust
Cloud Warehousing

DICOM Imaging Data Lake

Designed a petabyte-scale secure Data Lake on GCP for storing anonymized MRI/CT scans, utilizing Cloud Healthcare API for intelligent de-identification.

GCP Storage Cloud Healthcare API Python
Predictive Analytics

Claim Denial Probability Engine

Implemented an XGBoost model that intercepts outbound billing claims, predicting likelihood of denial and suggesting corrective coding actions in real-time.

XGBoost FastAPI AWS SageMaker
ETL Pipelines

State Registry Immunization Sync

Architected fault-tolerant daily batch ETL jobs to securely extract, encrypt, and upload millions of immunization records to state DOH registries via SFTP.

AWS Glue PGP Encryption SFTP
Data Security

Ransomware-Resilient Backup Arch

Designed an immutable, air-gapped backup strategy for critical clinical databases, ensuring point-in-time recovery capabilities in the event of ransomware attacks.

AWS Backup Object Lock Terraform
