Senior Full Stack Engineer / Healthcare · Government · Mobile

I build software that hospitals and governments can’t afford to have go down.

Ten years shipping production systems end to end — a hospital-wide Electronic Medical Record, the HR platform of a national ministry, and now a physiotherapy app on iOS & Android. Full stack by trade, business analyst by training.

Seniority is a feature.

Most of my career has been spent where software meets people with no patience for it — doctors between patients, HR officers processing pensions for civil servants, insurers reconciling claims. In those places a bug isn’t a ticket. It’s a nurse back on paper forms.

That’s where I learned the unglamorous half of engineering: moving paper workflows to digital without stopping operations, integrating with third-party systems that never behave as documented, and keeping a database fast in year eight.

I can sit with a head of department in the morning, write the PRD at noon, and ship the API and the mobile release by evening.

  1. 01

    Production, not demos

    A decade of systems that clinicians and civil servants use every working day.

  2. 02

    Business first, code second

    A Master’s in Business Analytics means I ask which metric a feature moves before I build it.

  3. 03

    End-to-end ownership

    Requirements, architecture, API, web, Flutter apps, store releases, servers and on-call.

  4. 04

    Boring tech, on purpose

    Proven stacks, clean architecture and written decisions — so the next engineer can keep it running.

Case files.

Systems that real people depend on — each opened like a chart: the problem, what I built, and what changed.

01 RME — Electronic Medical Record & Insurance Integration RS Manyar Medical Centre · Healthcare · 2023 — 2026

Hospital-wide EMR that moved clinical work off paper, with an integration layer to insurers and government health portals.

The problem

Clinical records lived on paper. Retrieving patient history was slow, insurance claims were manual, and every handover risked losing information.

What I built

An EMR built module by module alongside doctors and nurses, plus an API integration layer for insurers, external health networks and government portals.

Outcome

  • Paper-based clinical workflows moved to secure digital records
  • Automated insurance eligibility and claim verification
  • 99.9% availability for 24/7 clinical use
  • Doctor fee, revenue and appointment modules in one system
  • PHP
  • Laravel
  • C#
  • JavaScript
  • MySQL
  • REST API
02 HaiFisio — Physiotherapy Platform HaiFisio · Health-tech · Mobile · 2026

Booking and home-therapy tracking for physiotherapy patients, on iOS, Android and web.

The problem

Booking a physiotherapist and following a home-therapy programme is scattered across chat threads, paper and memory.

What I built

One Flutter codebase for iOS and Android, a REST API with real-time schedule sync, and a web back office for therapists.

Outcome

  • One codebase shipping to App Store and Google Play
  • Patient booking and therapy-progress tracking
  • Release pipelines, signing and provisioning owned end to end
  • Flutter
  • Dart
  • Laravel
  • Node.js
  • REST API
  • CI/CD
03 eHRM & SIMoLAK — Ministry HR Platform Kementerian PUPR · Government · 2016 — 2026

The web and mobile HR system of Indonesia’s Ministry of Public Works and Housing.

The problem

Leave, promotion and pension processes for ministry employees ran on manual, paper-heavy approval chains.

What I built

A web and mobile HR platform with automated workflows, personnel profiles and integrations with satellite applications.

Outcome

  • Leave, promotion, personnel profile and pension planning in one platform
  • Manual managerial processing replaced by automated back-end services
  • A decade of continuous delivery on the same platform
  • PHP
  • Laravel
  • JavaScript
  • MySQL
  • Mobile
04 Business Location Recommender (GIS + ML) Master’s thesis, ITS · Data & AI · 2025 — 2026

A model that recommends strategic business locations by combining geographic data with classification algorithms.

The problem

Expansion decisions are often made on intuition rather than spatial evidence.

What I built

Integrated Geographic Information Systems with classification models to score and recommend candidate locations.

Outcome

  • Geospatial feature engineering and classification pipeline
  • Data-driven framework for business expansion decisions
  • Python
  • GIS
  • Machine Learning
  • Predictive Modeling

Also built

  • 2014Speech Delayed KidsAn educational game helping parents teach vocabulary to children with speech delay — animals, fruits, sounds and puzzles.

A decade, one beat at a time.
