Job Success
Gujranwala, Pakistan - 10:01 am local time
I'm a senior developer on a pediatric health platform used by clinics across Italy. It runs on Medplum and FHIR R4. Since late 2025 I've shipped:
- A parent self-booking appointment engine, from the server-side scheduling logic through to the flows parents actually use
- FHIR AccessPolicy and consent models for families with two guardians, including record imports that repair themselves when data is missing
- Push notifications across two channels, web push and Firebase, behind a single dispatcher so a message goes out once regardless of device
- Regional health record data models and migrations built against Italian national clinical standards
- AWS deployment with CDK and Terraform, CodeBuild pipelines, SonarQube
Before this I spent four and a half years at an Italian company on .NET and Angular systems. I led the legacy migration to .NET Core there and cut downtime by roughly 40% by rebuilding the testing architecture.
What I can help with:
- FHIR and Medplum: resources, AccessPolicy, custom routing, HL7 v2, integrations like DoseSpot and Health Gorilla
- EHR and patient portals: scheduling, case management, consent, audit trails, role-based access
- LLM features in clinical products, where being reliable matters more than being impressive
- Backend: Node and TypeScript, NestJS, .NET 8 and 10, PostgreSQL, Prisma, Entity Framework
- Frontend: React, Next.js, Angular
- Infrastructure: AWS, Docker, Kubernetes, Terraform, CI/CD
I also take legacy work. .NET Framework to .NET 8 migrations, desktop applications moved to the web, DevExpress reporting, and old Classic ASP systems nobody wants to open. I've done all of those here on Upwork.
How I work: small branches, pull requests, and early warnings. If something is going to slip you will hear it from me before you have to ask. That matters more in healthcare than people expect. The expensive failures are rarely dramatic. They are a consent record that didn't save, or an access rule that was slightly too generous.
Send me the problem you're stuck on and I'll tell you honestly whether I'm the right person for it.
