Design & Build Distributed Services Implementing resilient, observable microservices and integration components (Java preferred; Node.js/JavaScript where appropriate).
Applying patterns for scaling, fault tolerance, idempotency, and backpressure in distributed environments.
API Platform & Kong APIM Configuring and managing Kong Gateway (routes, services, plugins, rate limiting, auth, mTLS, logging) via declarative config (YAML) and CI/CD.
Implementing gateway policies for security, traffic control, blue/green/canary releases, and zero-downtime migrations.
Integrations & Data Facades Building and maintaining a FHIR data facade that maps internal domain data to FHIR resources (read/search/transform), ensuring correctness and performance.
Developing backend integrations with downstream systems (REST, gRPC, messaging/queues) and handle schema/contract evolution.
API Engineering Owning the API lifecycle: design (OpenAPI), implementation, automated testing (unit/integration/contract), versioning, and SLO-driven operations.
Creating and maintaining OpenAI specs, mocks, and validation pipelines.
Security & Compliance Implementing OAuth2/OIDC flows, token introspection, and service-to-service auth.
Apply secure coding practices and least-privilege network policies; partner with InfoSec on reviews.

Networking Fundamentals: TCP/IP, DNS, TLS/mTLS, HTTP/2/HTTP/1.1, proxies, load balancing, and common troubleshooting (cURL, traceroute, etc.).
Data & FHIR Facade: Experience working with HL7 FHIR or adapters; familiarity with FHIR resource modeling and transformations (e.g., Patient, Observation, Encounter).
Testing & Quality: Unit, integration, and contract testing; test automation and CI/CD pipelines (YAML-based workflows).
Cloud & Ops: Experience deploying and operating services in a cloud or containerized environment (Docker/Kubernetes).
