Production AI · scalable backends · privacy-first software — built in the open.
I design production-grade AI systems and scalable backend infrastructure, with a focus on healthcare automation and high-performance LLM workflows. Currently a Software Engineer at DocNow EHR, where I've shipped production AI workflows that cut manual overhead by ~60%.
Away from the day job, I'm an open-source advocate with a conviction that software should respect the people who use it — no dark patterns, no silent data collection. That belief became Secure Suite: four privacy-first apps that keep every byte on the user's device.
Generative AI & LLMs · Python microservices for document intelligence & structured extraction
Backend Architecture · FastAPI · Django · Node.js (NestJS) · distributed system design
Real-Time Systems · WebSockets · SignalR · Socket.io
Computer Vision · PyTorch · OpenCV · ResNet pipelines
Privacy Engineering · AES-256-GCM · Argon2id · offline-first, on-device encryption
Privacy is the product. Four apps on one encrypted foundation. No servers, no accounts, no telemetry — data is encrypted on the device and never leaves it. All open source, MIT.
