Healthcare & SaaS Developer | HL7/FHIR, HIPAA, API & AI Integration

Job Success
Rawalpindi, Pakistan - 7:30 pm local time
Most developers can build a web app. Far fewer understand what it means to build one that handles protected health information, integrates with legacy EMR systems over HL7 v2, stays compliant under HIPAA, and still ships on a startup timeline. That's the gap I fill.
WHAT I BUILD
→ HL7 v2 and FHIR R4 integration pipelines — connecting EMR systems, patient portals, labs, and third-party health APIs that weren't designed to talk to each other. I've handled ADT, ORM, ORU, and SIU message types, and built the error handling and audit logging that compliance requires.
→ HIPAA-compliant SaaS platforms — multi-tenant architecture with proper access controls, role-based permissions, data encryption at rest and in transit, and audit trails. Not bolted on at the end — built in from the start.
→ AI-assisted clinical and admin workflows — OpenAI and LLM integrations that actually make sense in a healthcare context. AI features that surface the right information, reduce manual data entry, and fit into how clinical teams actually work. Nothing added just because it's trendy.
→ EMR and EHR API integrations — connecting platforms like Epic, Athena Health, AdvancedMD, and Practice Fusion to modern SaaS products via FHIR R4 APIs, SMART on FHIR launches, and custom middleware.
→ Full SaaS infrastructure — Stripe billing, subscription management, multi-tenancy, onboarding flows, admin dashboards, real-time reporting, and the backend APIs that tie everything together.
→ Operational and business SaaS platforms outside healthcare — admin dashboards, logistics/fleet tracking, and e-commerce backends (Stripe/PayPal checkout, multi-vendor marketplaces) for clients who need the same reliability and clean architecture without the compliance layer.
MY STACK
Backend: .NET Core (ASP.NET Core, Entity Framework, C#), Node.js, NestJS
Frontend: React, Next.js, TypeScript
Cloud: Microsoft Azure, AWS
Databases: PostgreSQL, SQL Server, MongoDB
Integrations: OpenAI API, Stripe, Twilio, third-party health APIs
DevOps: Docker, CI/CD pipelines, Azure DevOps
HOW I WORK
I've worked with early-stage startups building from scratch and with established teams adding features to existing platforms. Both are different, and I'm comfortable with both.
For early-stage work, I move fast, ask the right questions upfront, and build things that can scale — not just things that work today. For existing codebases, I take time to understand what's there before touching anything.
I don't take every project. If the scope isn't clear, the timeline isn't realistic, or the fit isn't right technically, I'll say so before we start rather than halfway through. That's saved a lot of clients from painful projects.
WHO I WORK BEST WITH
Health-tech startups building their first SaaS product or a new feature set. Founders who have validated their idea and need a developer who understands both the engineering and the regulatory layer. Teams that want clear communication, honest timelines, and work that doesn't need to be redone.
If your project sounds like what I described above, I'd be happy to jump on a quick call. I charge $5 for a 30-minute intro — just to make sure we're aligned before either of us commits to anything.
