3+Integrated LLM providers behind a server-side layer, so model credentials and patient data never reached the browser

1+Joined as founding engineer and built the AI scribe end to end — streaming consultation audio to Deepgram for real-time speech-to-text, then using OpenAI to turn the transcript into structured clinical documentation
2+Built the product on Next.js, including authentication, consultation history, and a review step so clinicians could edit and approve every generated note
3+Architected and deployed the full cloud-native system on AWS EKS, containerizing services and running them on Kubernetes
4+Developed secure APIs for real-time medical transcription workflows, keeping provider credentials and audio off the client

2+Built the training system in PyTorch with Flower for FedAvg aggregation and Opacus for per-sample gradient clipping and calibrated Gaussian noise, evaluated across simulated clients on MNIST
3+Analyzed four attack surfaces — data breach, membership inference, model inversion, and linkage — and mapped each to the technique that mitigates it
