Clinical Medical Physicist & Software Developer · Rio de Janeiro, Brazil 🇧🇷
I work at the intersection of clinical radiotherapy and software engineering — building open-source tools that close the gap between treatment planning systems and the clinical reality around them.
🔹 ESAPI-Offline-Compiler — Compile Varian Eclipse (ESAPI) scripts without Visual Studio, using just a .bat file and csc.exe.
🔹 patient-plan-explainer — Turns DICOM-RT treatment plans into patient-friendly explanations. PDF + audio, Brazilian Portuguese.
🔹 dicom-tag-explainer — Upload a DICOM file, get an LLM-powered plain-language explanation of every tag, categorized by clinical relevance.
🔹 eclipse-dicom-fix — Re-encodes compressed DICOM files (JPEG Lossless, JPEG 2000) to Implicit VR Little Endian for clean Eclipse TPS import.
🔹 dicom-rt-explained — A practical, code-first guide to DICOM-RT for developers entering radiation oncology. Bilingual (EN / PT-BR).
🔹 Radioterapia.AI (private) — AI-powered clinical platform for radiation oncology workflows. Co-founded with Dr. Henrique Braga.
Clinical Medical Physicist & Radiation Protection Supervisor at Oncobarra (Rio de Janeiro). Daily work spans Varian Eclipse / ARIA, IMRT, VMAT, DIBH, 3D-CRT, and HDR gynecological brachytherapy.
Previously: supervising physicist during the installation of a Varian Halcyon with HyperSight at Hospital de Saúde da Mulher (Belém), and clinical roles at Oncoclínicas (Latin America's largest oncology network) and others.
- PhD in Physics — Centro Brasileiro de Pesquisas Físicas (CBPF), 2015
- Doctoral research within the CMS Collaboration, CERN
- CNEN-certified Radiation Protection Supervisor (Radiotherapy)
- CNEN-certified Medical Physics Specialist (Radiotherapy)
- 6+ years of clinical practice across four Brazilian radiation oncology services
Clinical: Eclipse · ARIA · ESAPI · PDSAPI · DICOM-RT
Also: pydicom · Three.js · WeasyPrint · ReportLab · Cloudflare Pages/Workers · D1 · Git · GitHub Actions
AI: Anthropic Claude API · Google Gemini API · LLM integration in clinical workflows
Always open to conversations about:
- DICOM-RT processing and validation
- Clinical workflow automation
- AI applied to radiation oncology
- Open-source tooling for cancer care
This profile reflects my open-source / public work. The intersection of clinical practice and software development is where I keep finding the most interesting problems.
