I turn coffee into code.

Fullstack developer from Batam, running on good coffee since 2007. I build fast, maintainable web apps, backends, and IoT systems for teams in Singapore and beyond.

What I build

End-to-end delivery: from scope to production and monitoring.

01Web & Mobile Apps (Fullstack)Dashboards, admin panels, and native mobile apps (Ionic/Flutter) with a premium feel.

02Backend & Data (Python/Go)Clean, reliable APIs built for scale, operations, and long-term maintenance.

03IoT (MQTT) & MonitoringDevice → broker → pipeline → dashboard → alerts, designed for reliable data and easy operations.

02Selected Work

Proof without breaking NDA

No public client portfolio. Instead: anonymised engagement snapshots — context, work, outcomes.

Operations & service

Context —: Team needed a fast dashboard for daily KPIs and incident investigation.
Work —: Designed data model, built responsive UI, and improved queries + caching.
Outcome —: More consistent data access; reduced ops overhead via clear drill-down flows.

Next.js
Postgres
Redis

Internal workflows

Context —: Manual approvals created bottlenecks and input mistakes.
Work —: Built a web app with RBAC, audit trails, and status notifications.
Outcome —: Cleaner approvals; better status visibility; less rework with validated inputs.

Node.js
Postgres

System integration

Context —: Existing APIs were brittle and hard to trace during incidents.
Work —: Refactored critical endpoints, improved error handling, added useful logs/metrics.
Outcome —: Faster incident handling thanks to better observability; safer releases.

IoT & monitoring

Context —: Needed realtime device monitoring + history, plus threshold-based alerts.
Work —: Designed MQTT topics and payload schema, built data pipeline, and realtime dashboard.
Outcome —: Easier visibility; more actionable alerts; faster troubleshooting.
