I'm Prasanjith Chanaka, a health informatics and digital identity engineer based in Sri Lanka. I build production software at the intersection of health informatics, digital ID systems, and agentic AI — from EHR and medical data platforms to LangGraph-powered clinical workflow agents.

My work spans Python AI pipelines, OCR with vision models, RAG systems, and full-stack apps in React, Node.js, and Flutter. I care about shipping systems that are fast, reliable, and actually used.

What I do

  • Health informatics — EHR/EMR, medical records, diagnostics, HL7 FHIR interoperability
  • Digital identity — digital ID systems, identity verification, secure patient identity
  • Agentic AI & LangGraph clinical workflow systems
  • Full-stack development (React, Node.js, Laravel, Flutter)
  • AI integrations — DeepSeek, NVIDIA NIM, vision/OCR models
