I turn chaosinto code.
From mobile apps to bare metal servers — I've been building the technology companies actually run on since 2020.
I'm Mathew — I run the entire technology stack for a retail distribution company in Bali. Every system, from the mobile apps in the hands of sales reps to the bare metal servers in the rack. If it has code or a blinking light, it's probably mine.
Within months of joining, I was handed full IT leadership — not because I asked for it, but because the systems I kept building made operations faster and cheaper. The warehouse app I built? Designed for operators wearing gloves — 56dp touch targets, optimized for scanning at speed. The management system? Replaced a mess of spreadsheets with real-time margin analysis our entire sales team now depends on daily.
I hold a B.Sc in Information Systems from President University (scholarship), scored a perfect 100% on AWS Cloud Architecting, and won a hackathon along the way. But honestly, I care more about whether the system works at 8am Monday morning than any certificate on a wall.

How I work
Understand
I dig into the actual problem — not the symptom. What's costing time? What breaks on Monday morning? I talk to the people who'll use the system.
Architect
Map the data flow, pick the right stack, design for the constraints that actually matter. No over-engineering — just what needs to exist.
Build & Ship
Working software, fast. I build in iterations — get it in front of users early, fix what's wrong, ship what works. Production-ready, not demo-ready.
Maintain & Evolve
Systems don't end at launch. I monitor, optimize, and evolve them as the business changes. The best code is code that keeps working.
Systems that ship
01 / 06Crystal Management System
2025–PresentThe sales team was drowning in spreadsheets. I built an internal ERP that replaced all of it — real-time margin analysis, automated pricelist management with tax calculations, rolling budgets that calculate themselves. The entire sales team uses it daily.
Customer Loyalty App
2025–PresentA loyalty app that actual customers use — not a demo. Points system, vouchers, push notifications, the full stack. Built in Flutter, shipped on Android, and handling real transactions for a retail brand.
Corporate Website
2025–PresentThe company needed a public face. I built it with static architecture for speed — CDN delivery, HSTS, HTTP/3, proper Open Graph previews. Loads fast, ranks well, looks professional.
Warehouse Management System
2025–PresentWarehouse operators wear gloves. Every button had to be big enough to hit with a fist — 56dp touch targets, zero-friction scanning. Stock transfers, receive/send operations, all synced against purchase and sales documents in real-time.
Enterprise Server Infrastructure
2024–PresentI racked the server, configured the networking, set up the storage arrays, and containerized the databases. HP ProLiant with iLO remote management, TrueNAS for storage, MikroTik for networking — all running in production.
ERP Integration Layer
2023–PresentThe legacy ERP couldn't talk to anything. I built the bridge — a custom integration layer that syncs data automatically between the old system and every new app I've built. Security-hardened with role-based permissions.

What people say
When Mathew joined, we had disconnected systems and manual processes everywhere. Within months, he built an integrated management system that our entire sales team now depends on daily. He does not just fix problems — he eliminates them permanently.
