Engineering challenges

What made it hard — and how we approached it

The problems
01

Full-Stack Healthcare Platform Development

Building both frontend and backend systems that could handle complex healthcare workflows while maintaining compliance with medical regulations.

02

Administrative Task Automation

Creating intelligent systems to automate routine administrative tasks without compromising accuracy or compliance requirements.

03

Clinical Decision Support Implementation

Developing reliable decision support systems that could assist healthcare providers with evidence-based recommendations while respecting clinical judgment.

04

Patient Engagement Tool Design

Designing engaging and accessible tools that could effectively involve patients in their care journey while accommodating varying levels of health literacy.

Our approach

Healthcare-Specific Architecture

Implemented a specialized architecture that addressed healthcare-specific requirements including HIPAA compliance, audit trails, and clinical data models.

Frontend-Backend Integration Strategy

Developed a coordinated development approach where frontend and backend teams worked in tandem with shared data models and API contracts to ensure seamless integration.

Workflow Automation Engine

Built a sophisticated workflow engine that could model complex healthcare processes and automate administrative tasks while maintaining appropriate human oversight.

AI-Powered Clinical Support

Integrated medical knowledge bases and machine learning models to provide contextually relevant clinical decision support while maintaining transparency in recommendations.

Patient-Centered Design Process

Employed a collaborative design process involving patients, clinicians, and administrators to create engagement tools that addressed real needs and usage patterns.

Technical architecture

HIPAA-aware serverless workflow engine wrapped around an LLM core

CareGPT is an AI assistant for healthcare providers that automates administrative work, offers clinical decision support and drives patient engagement. Python services run as serverless functions and Docker containers across Azure and AWS, with an LLM orchestration layer that grounds OpenAI model calls in curated medical knowledge and always routes outputs through human review. A serverless-first shape fit the bursty, task-shaped nature of clinic workflows while a containerized workflow engine handles long-running processes.

Clients

A React web application for clinicians and administrators, plus a patient-facing engagement surface for reminders, questionnaires and follow-ups.

  • React clinician workspace
  • Admin automation console
  • Patient engagement portal
  • Notification channels

API & edge

An authenticated gateway enforces identity, consent and rate limits before any request reaches services that touch patient data.

  • API gateway
  • Identity provider and SSO
  • Consent and scope checks
  • Request audit logging

Core services

Python services split into short serverless tasks and a containerized workflow engine that models multi-step clinical and administrative processes with human checkpoints.

  • Workflow automation engine
  • Administrative task functions
  • Decision support service
  • Patient engagement service
  • Document and note drafting

Data

Clinical and operational data are stored encrypted with an immutable audit trail; a vector index holds the knowledge used to ground AI answers.

  • Encrypted clinical data store
  • Immutable audit ledger
  • Medical knowledge vector index
  • Task queues
  • Document object storage

AI / integrations

An orchestration layer builds grounded prompts, calls OpenAI models, validates outputs and attaches citations before anything reaches a clinician.

  • LLM orchestration layer
  • OpenAI models
  • Retrieval over medical knowledge bases
  • Output validation and guardrails
  • EHR and scheduling connectors
  • SMS, email and WhatsApp provider

Infrastructure & delivery

Serverless functions and Docker containers deployed across Azure and AWS with infrastructure as code and environment isolation per institution.

  • Azure and AWS serverless functions
  • Docker container services
  • Per-tenant environment isolation
  • Secrets management
  • CI/CD with compliance checks
Request lifecycle
  1. 01

    A clinician asks the assistant to summarize a visit or draft a follow-up; the gateway verifies identity, role and patient consent.

  2. 02

    The workflow engine opens a task, pulls the relevant records from the clinical store and writes an audit entry.

  3. 03

    The orchestration layer de-identifies where possible, retrieves guidance from the medical knowledge index and builds a grounded prompt.

  4. 04

    The OpenAI model returns a draft; guardrails check it for unsupported claims and attach the sources it relied on.

  5. 05

    The clinician reviews, edits and approves the output in the React workspace; nothing is filed without human sign-off.

  6. 06

    The engagement service sends patient reminders or questionnaires via the messaging provider and records responses into the workflow.

Key decisions

Human-in-the-loop by design

Decision support must respect clinical judgment and regulation, so every AI output is a draft routed to a clinician for approval rather than an automatic action. This preserved trust while still cutting administrative workload by 30%.

Retrieval-grounded prompts over raw LLM answers

Grounding each call in curated medical knowledge bases and returning citations made recommendations transparent and auditable, which a general-purpose chat interface could not offer.

Serverless tasks plus a containerized workflow engine

Clinic workloads are bursty and task-shaped, so serverless functions keep idle cost near zero, while multi-step processes with waits and approvals run in a Docker-hosted engine that holds state reliably.

Audit trail as a first-class data store

Healthcare compliance demands knowing who saw and changed what, so an immutable ledger sits beside the clinical store instead of being bolted onto application logs later.

Security & compliance
  • HIPAA-aligned controls: role-based access, minimum-necessary data retrieval and patient consent checks enforced at the gateway.
  • PHI encrypted at rest and in transit, with de-identification applied before data is sent to external AI models where the workflow allows.
  • Immutable audit trail of every record access, AI request and clinician approval for compliance review.
  • Per-institution tenant isolation and secrets management across Azure and AWS environments.
  • AI guardrails validate outputs, block unsupported clinical claims and require human sign-off before anything is filed or sent to a patient.
