About
Engineering with a business brain.
Since 2021 I've built software inside one of Indonesia's largest mining groups — where downtime is expensive, users are non-technical, and "it works on my machine" doesn't count. That environment taught me to ship things that are reliable first and clever second.
I care about the unglamorous details: offline states, edge cases, load times, and whether the person using the tool actually gets home earlier because of it. The result is a track record of systems that stay in production — 10+ mobile apps, a company-wide workflow platform, and 50+ client projects through my studio.

Selected work
Real systems, measured results.
Not concept shots — production software with business impact you can put a number on.
Enterprise · Workflow Automation
Merdeka Workflow System
Role — Lead EngineerReact · Joget · n8n · REST
Challenge
Internal approvals at a multi-site mining group ran on paper and email — routine requests took days and nobody could see where they were stuck.
Solution
A custom workflow platform with multi-level approval routing, automatic notifications, and a live monitoring dashboard for every department.
Impact
Approval time down 70%. Full process transparency for management.
Enterprise · Mobile Suite
Field Operations Apps
Role — Mobile DeveloperReact Native · Flutter · Firebase
Challenge
Field teams across mining sites reported through spreadsheets and chat groups — data arrived late, inconsistent, and unauditable.
Solution
A suite of 10+ purpose-built mobile apps for inspections, reporting, and logistics — offline-first, synced when connectivity returns.
Impact
Standardized reporting across sites; hours of manual entry eliminated daily.
Business System · Inventory Management
Grebit Inventory Management System
Role — Lead DeveloperReact Native · Next.js · Tailwind CSS · REST API
Challenge
The client relied on manual stock opname processes that were slow, difficult to monitor, and prone to human error across warehouse operations.
Solution
Built an integrated inventory management system — a React Native mobile app for warehouse staff and a web dashboard for administrators — enabling centralized inventory tracking and reporting.
Impact
Streamlined inventory operations, improved stock visibility, and enabled faster reporting through one centralized platform.
Healthcare · Web Platform
Klinik Hana
Role — Design & EngineeringReact · TanStack · Supabase · WhatsApp API
Challenge
Patients couldn't find schedules or book visits online — the clinic was losing inquiries to phone tag and outdated listings.
Solution
A fast, mobile-first site with real-time practice schedules, staff profiles, and one-tap WhatsApp booking.
Impact
+180% new patient inquiries within the first three months.
Technology
Tools chosen for longevity.
A deliberately boring core — proven, maintainable, fast — with new tech adopted only when it earns its place.
