Cursor AI App Debugging and Completion
Dereje is an exceptional developer! I hired a total of 6 developers, and he was the last one standing at the end of the project because he was the best! He's great, very reliable, can fix things quickly, is prompt, and overall has been an incredible first hire. Ending the contract because the job was completed successfully.

Full Stack Developer
Dereje delivered good work on this React development project and I enjoyed working with him. His communication was top-notch, he met all deadlines, and his skills were reasonably strong. At one point I asked for an additional milestone and he was very forthcoming that the additional work was outside his area of expertise. I enjoyed working with Dereje and will likely have additional jobs for him in the future.
About Dereje
FDA-Cleared Healthcare AI Architect | EHR/FHIR & HIPAA SaaS Systems
100%
Job Success
Addis Ababa, Ethiopia - 4:23 pm local time
Over the past year, I've built confidence-gated AI workflows for clinical decision support, real-time teleguidance infrastructure connecting remote specialists to on-site clinicians, and multi-tenant HIPAA-grade data isolation for platforms handling live patient data.
Founders and clinical teams bring me in when the system has to work correctly the first time, not just demo well. I write to FDA-grade documentation standards and build clean, modular, production-ready code designed to run unattended under real clinical load.
HEALTHCARE INTEROPERABILITY & EHR INTEGRATION
FHIR R4 & HL7 Standards: Built FHIR-compliant API pipelines and AWS HealthLake integrations connecting AI inference engines directly to EHR workflows.
EHR & EMR Integrations: Experienced with FHIR REST APIs and webhook integrations for Epic, Cerner, AthenaHealth, Medplum, and OpenEMR.
DICOM & PACS Medical Imaging: Architected DICOM image ingest and metadata processing pipelines for ultrasound analysis using Orthanc PACS, OpenCV, and ONNX runtime.
HEALTHCARE AI & SAFETY-CRITICAL SYSTEMS
FDA-Cleared AI Platform: Architected live video teleguidance and AI inference backend, onboarded across 45+ clinics, processing 1,200+ sessions with 99.9% uptime and 450ms analysis response time.
Confidence-Gated RAG (First Aid RAG): Built LangGraph state machines with strict confidence gating, routing sub-85%-confidence requests to clinician review queues, achieving 100% recall on emergency escalations.
Medical Vision Analysis: Built ONNX runtime and OpenCV preprocessing pipelines on AWS Lambda, analyzing 5,000+ ultrasound images with a 94% specialist confirmation rate.
HIPAA SECURITY & INFRASTRUCTURE
HIPAA Cloud Infrastructure: Built an open-source Terraform IaC library reducing healthcare compliance setup from 6 months to under 5 days, with 100% PHI redaction across all 18 HIPAA identifiers.
Real-Time Telehealth Media: Integrated Zoom Video SDK and low-latency WebRTC streaming for live specialist guidance and remote clinical collaboration.
BEYOND HEALTHCARE
I bring 5+ years of full-stack and cloud architecture experience, including microservices, event streaming, and AI agent workflows, so I can take a healthcare platform from architecture through production without needing to hand off to a second team.
TECH STACK
Healthcare & Compliance: HL7 FHIR R4, HL7 v2, DICOM/PACS (Orthanc), Medplum, OpenEMR, HIPAA Compliance, PHI Redaction
EHR & Cloud Health APIs: AWS HealthLake, Google Cloud Healthcare API, Epic/Cerner/AthenaHealth APIs
Frontend: React, Next.js, TypeScript, TailwindCSS
Backend & Data: Python, FastAPI, Node.js, PostgreSQL (RLS), SQL Server, Redis
AI, RAG & Agents: LangGraph, LangChain, Qdrant, Pinecone, OpenAI, Claude, Gemini Vision
Cloud & Infrastructure: AWS (Lambda, ECS, Fargate, S3, KMS), Docker, Terraform, CI/CD
