About Me
Who I Am
I am Jagadesh Ata, a Senior Go (Golang) backend engineer focused on
healthcare interoperability. I build FHIR R4 APIs and HL7 v2 integration
services that run on Kubernetes and remain reliable under production
clinical workloads.
I value systems that are boring in production: predictable behavior,
strong contracts, clear traceability, and practical observability.
US-based in St. Louis, open to remote roles.
Focus Areas
| Focus |
What I deliver |
| FHIR R4 and HL7 v2 |
Interoperability services that validate, normalize, and translate
clinical data with audit-ready lineage. |
| Go backend engineering |
REST and gRPC services with versioned APIs, contract tests, and
pprof-driven tuning. |
| Kubernetes Go development |
CRDs, controllers, and operators that remove toil and enforce
platform standards. |
| Reliability and observability |
OpenTelemetry, Prometheus/Grafana, and structured logs for
end-to-end traceability. |
Technical Depth
Interoperability Engineering
- FHIR R4 REST APIs with search, pagination, Bundles/transactions, and
conditional create/update.
- HL7 v2 to FHIR translation with validation, mapping, normalization,
and enrichment.
- Idempotent processing and replayability using correlation IDs and
structured audit trails.
- Validation against profiles and implementation guides to prevent
data drift.
Go Services
- REST and gRPC APIs with OpenAPI specs and contract testing.
- Concurrency patterns with predictable error handling and
pprof-driven tuning.
- Versioning strategies for long-lived clinical integrations.
Kubernetes-Native Go
- Controllers and operators with controller-runtime and
operator-sdk.
- GitOps workflows using Argo CD or Flux for repeatable
deployments.
- Security guardrails including RBAC, NetworkPolicies, and Pod
Security Standards.
