The challenge

Clinical reporting is high-stakes text generation under regulatory constraint: how do you apply generative AI where an invented detail is a safety issue, and every byte of patient data is governed?

What we built

Fine-tuned LLMs with QLoRA where prompting alone fell short, LangChain retrieval pipelines to ground generation in the right clinical context, and engineered prompts tested against real reporting workflows. Around the models: HIPAA-compliant full-stack engineering — React/TypeScript frontends, Python microservices for AI orchestration, end-to-end encryption, real-time inference — and the MLOps to run it, with Kafka pipelines and Airflow-orchestrated workflows spanning ingestion, training, evaluation and deployment.

Key engineering

The decisions that made it work

Fine-tuning under constraint

QLoRA adaptation on clinical language, evaluated before deployment rather than assumed.

Grounded generation

Retrieval pipelines feeding the model the patient-specific context it must not invent.

MLOps end to end

Ingestion → training → evaluation → deployment as one orchestrated, repeatable pipeline.

The results

What actually changed

  • 1

    Context-aware reporting time cut 25% on a platform clinicians use daily

  • 2

    Model latency down 60% and deployment cycles down 50% from the MLOps rebuild

  • 3

    Delivered HIPAA-compliant end to end — encryption, access control and auditability included
