Hi, I'm Sivanajani, a software engineer working at the intersection of healthcare and technology. After completing my B.Sc. in Medical Informatics at FHNW, I'm now pursuing my M.Sc. in Medical Informatics — while building real products on the side:
🚀 Freelance Fullstack Developer @Swiss NTech · 🎨 Web Design, Development & Support @ alpinelink GmbH
I love building software end to end: from React/TypeScript frontends over FastAPI & Spring Boot backends to Docker, cloud infrastructure and AI-powered features like RAG systems for medical documents.
Languages: Python · TypeScript · JavaScript · Java · Kotlin · SQL · Google Apps Script · C · C++
Frontend: React · Vite · Tailwind CSS · Material UI · Framer Motion · Zustand · React Router
Backend & APIs: FastAPI · Spring Boot · Node.js · Express · REST APIs & Microservices · Hibernate · MapStruct
Data & AI: NumPy · Pandas · PyTorch (Vision Transformer) · spaCy · LLM-based extraction & RAG (Google Gemini) · medical datasets (DICOM, PROMs/CROMs, Parkinson)
Infrastructure & DevOps: Docker · Terraform · GCP · PostgreSQL · Supabase · Linux · Apache/Nginx · Orthanc (PACS) · GitHub Actions & CI/CD
Monitoring: Prometheus · Grafana · Netdata · cAdvisor
CMS & Web: WordPress (client sites, maintenance & support)
