Bridging clinical multiomics with scalable technology · HL7 FHIR interoperability · agentic AI · precision-medicine systems
I bridge two worlds that usually do not talk to each other: clinical medicine and scalable engineering. My work turns agentic AI, multiomics and hard interoperability standards into systems that hospitals can run on a Monday morning — not slideware that impresses on a Friday.
The turning point of that work was leading data standardisation for SATUSEHAT, Indonesia's national health interoperability platform. That is where FHIR R4, terminology mapping and master data management stopped being theory and became a national contract between thousands of facilities. Everything I have built since inherits that constraint: the payload must be right, in production, for people who will never read the spec.

Agentic assistants and decision support where the model proposes and deterministic rules decide. SmartClaim checks diagnosis, procedure and financing codes before a claim is submitted; IvanMD's CDS grounds suggestions in the encounter's SOAP; WISH turns a receipt photo into structured spending that three different assistants can reason over. Author of the open-source SATUSEHAT integration library — PHP, Node.js, Python and Go — plus SmarTerm, one terminology engine for ICD-10, ICD-9-CM, LOINC, SNOMED CT, KFA and KPTL. Running against the national platform, not a sandbox. Contributor to the national FHIR Indonesia Implementation Guide — the ID Core profiles (id-core-*) that SATUSEHAT payloads are validated against, built from FSH in CI. |
IDeRare — phenotype-driven exome analysis, published in JAMIA Open — and OMOP↔FHIR exchange for GWAS risk stratification. Genomic data is only useful when it reaches the clinician who is making the decision, in the format their system already speaks. EMR, LIS and ERP surfaces built for real hospital workflows: IvanMD, Clinix, SPECTRA. My clinical pathology practice — laboratory interpretation and whole-exome sequencing — is what keeps these architectures honest. |

Editor-time metrics stopped being honest the moment agents started writing code with me: hours fell while shipped work rose. This block therefore measures what landed — commits, pull requests, reviews, repositories touched — and whether the services behind them are answering right now.

Standards — HL7 FHIR R4, SATUSEHAT, ICD-10 / ICD-9-CM / INA-CBG, SNOMED CT, LOINC, KFA, KPTL, HPO, OMIM, ORPHA, OMOP, DICOM.
AI — agentic pipelines, RAG, prompt engineering, LangChain; scikit-learn, PyTorch/Keras for imaging and omics.
Backend — PHP 8 / Laravel, Python (FastAPI, Django, Streamlit), Node.js, Go; PostgreSQL, MariaDB, Redis; OIDC (Passport), Sanctum.
Frontend — Next.js, Vue 3 + Inertia, React, Tailwind, Vite.
Platform — Docker, GitHub Actions, Vercel, Cloudflare, aaPanel; zero-build deploys where the server may only git pull.
Conventions — code symbols in English, UI text in Indonesian; every change carries a test quoted before and after; a feature is done when it can be triggered through the API, not only through a dashboard.
The SDKs, the FHIR implementation guidance and the small utilities here are built in the open, most of them on unpaid time. If one of them saves you a week of integration work, you can sponsor the work — or send a change back. Bug reports, corrected profiles and better examples count just as much as code.
Advisory, architecture review, or hands-on delivery for health AI, FHIR/terminology infrastructure and clinical data platforms.
