Hassan B.

I build software for regulated industries, where mistakes carry statutory damages. Healthcare: HL7/FHIR interfaces, DICOM imaging pipelines, EHR integration, ML that runs where PHI lives. 20+ real-world projects shipped. $1.8M+ earned across client engagements. Everything below is live in production. You won't spend our first call explaining what a 271 or a STOW-RS is. **WHAT I BUILD** - HL7 v2 to FHIR R4 integration: feed normalization, SMART-on-FHIR apps, CDS Hooks services, EHR vendor APIs (Epic, athenahealth, NextGen) - Medical imaging: DICOM pipelines, de-identification, MONAI segmentation models - Remote patient monitoring: wearable APIs (HealthKit, Health Connect, Samsung Health), Knox device fleets, BigQuery analysis, FHIR write-back to the EHR - On-device clinical ML: transcription, translation, structured notes, zero PHI egress - Compliance solutions leveraging advanced ML & Knowledge Graphs **RECENT WORK, ALL IN PRODUCTION** - The University of Chicago geriatric-oncology researchers: wearable RPM platform, 9 data streams, minute-level wear detection, curated EHR write-back. I tech-led it across 3 SOWs over 12 months. - Live in a 600-patient long-term-care pharmacy: OCR label verification with pharmacist e-signature chains. Saves 45 minutes of staff time daily. 14% fewer verification errors. - Point-of-read decision support for adiologists at a major U.S. health system (NDA): 133-structure brain-MRI segmentation on Azure, DICOMweb PACS integration, FHIR Observations to the EHR. - Multilingual medical documentation for emergency, bedside, and outpatient workflows (publicly-traded digital-health company, NDA): 119 languages, sub-0.5s response, fully offline on facility hardware. Translators workforce reduced by 5%. - Messaging-compliance platform for a U.S. automation firm (NDA): business-texting registration automated across 4 production deployments, including two major U.S. communications platforms. Now generating $65K+/month in recurring revenue. **WHO YOU WORK WITH** I architect and tech-lead every build personally, with specialist collaborators when a build needs them. 5+ years hands-on. Computer Science degree with a Machine Learning minor. No learning healthcare on your dime. **HOW I WORK** Fixed micro-milestones against acceptance criteria you define. Clear communication. Working code early, usually week one. Post-delivery support windows on every build. Scope changes are ALWAYS welcomed! **DOMAINS & STANDARDS** HL7 v2 · FHIR R4 · SMART on FHIR · CDS Hooks · DICOM · PACS · SNOMED CT · eMAR · RCM · telehealth · remote patient monitoring · TCPA · 10DLC · HIPAA · IEC 62304 documentation · SOC 2-ready architecture **STACK** Python · C# · Java · FastAPI · React · TypeScript · PostgreSQL · MONAI · PyTorch · Mirth Connect · GCP · Azure · Docker · AWS
