[01] // Custom POS · Cloud Infrastructure
Pangsit Mie Ayam Aman
The client wanted a dedicated Point-of-Sale system without ongoing monthly SaaS fees or restrictive vendor lock-in.
Engineered a one-off, self-hosted POS system featuring multi-branch scalability, role-based access control, and complete offline/online sync.
[02] // Custom POS · Operational Automation
Just Some Coffee
The business needed an efficient way to manage bulk coffee pre-orders alongside automated, real-time Cost of Goods Sold (COGS) tracking.
Built a bespoke POS platform tailored for pre-order scheduling with an integrated dynamic recipe and COGS calculation engine.
[03] // Internal Tooling · Inventory Management
8888 Gadget
The business was tracking high-turnover smartphone trades on fragmented spreadsheets, leading to inventory discrepancies and unclear margin tracking.
Developed a dedicated internal inventory web platform featuring instant device lookups (IMEI/model), automated condition logging, and real-time margin calculators.
[04] // SaaS Product · Founder
Utascan
Manual Threads monitoring is slow, noisy, and causes teams to miss high-intent leads and competitor moves.
I built Utascan to automate this. It monitors targeted keywords on Threads in real time, filters noise, and sends instant alerts so you never miss a lead.
[05] // macOS Utility · Native Interface · System Integration
Renotch
The MacBook notch sits as an unused hardware cutout on the screen rather than an active, functional part of the daily workflow.
Developed a native macOS utility that transforms the notch area into an interactive dynamic hub, featuring a seamless music player controller and quick-access widget tools.
[06] // Web Design & Development · Brand Presence
Bali International Dental Center (BIDC)
Despite being a premier dental clinic in Bali, the business lacked an authoritative digital presence to attract and convert overseas patients.
Designed and developed a modern, multilingual company profile optimized for international credibility, patient trust, and seamless appointment inquiries.
