About Me

I'm a physician and computer science undergraduate exploring how software engineering and artificial intelligence can advance radiological practice. My radiology experience is hospital-based diagnostic imaging, including emergency/trauma and oncologic care. I have hands-on contributions to DICOM viewers, PACS infrastructure, and exploratory AI tooling for healthcare and medical imaging, and I'm comfortable moving from clinical questions to code and back. My main technical interests include:

  • DICOM viewers with 2D/MPR/volumetric rendering and DIMSE/DICOMweb integration
  • Generative AI in medicine (LLMs/Agents, local inference, RAG/finetuning)
  • Infrastructure for healthcare systems (PACS, NAS, EHR, and other systems)
  • AI-assisted software engineering and developer tooling
  • Full-stack development tailored to clinical workflows

Tech Stack

  • Languages: Python · Swift · C++ · Dart · JavaScript · Java
  • Frameworks: Django · SwiftUI · Metal · Flutter
  • AI/ML: PyTorch · TensorFlow · scikit-learn
  • Medical Imaging: DCMTK · GDCM · VTK · ITK · DcmSwift · OsiriX/Horos · 3D Slicer · Orthanc
  • Infra / DevOps: Docker · Proxmox · QNAP (& other open source NAS) · Tailscale · Git
  • Setup: macOS + Windows, Linux VMs, NAS with Dockerized services
  • Experimenting with: CUA (Computer Use Agents), Ollama, ComfyUI

Interests

  • Local-first imaging platforms and DICOM viewers
  • AI applications in medicine
  • PACS servers in low-resource environments
  • AI-assisted radiological decision-making

Current Projects

Isis DICOM Viewer (Windows, macOS, iOS, iPadOS): built natively in Swift for Apple platforms and developed in Qt/C++ for Windows, providing 2D visualization, MPR, volumetric rendering, PACS/DIMSE support, and ROI measurement tools (closed source).

MTK — Metal Toolkit: Modern Swift/Metal toolkit for high-fidelity medical imaging (volume rendering, SceneKit integration, SwiftUI components)

JFlutter: Cross-platform interactive educational tool to design and simulate automata, regular expressions, formal languages and Turing machines. Mobile‑first, touch‑optimised UI.

Other Projects

DICOM-Decoder: DICOM Pixel decode & windowing pipeline

DcmSwift: Swift-native DICOM core (DIMSE + DICOMweb)

TotalSegmentator Horos Plugin: Bringing the modern TotalSegmentator to the open-source Horos Project!

WALL-ET: Mobile Bitcoin wallet (WIP)

Orthanc for QNAP: Custom .qpkg packaging

LLMs + Radiology: Fine-tuning and RAG pipelines with anonymized radiology data
