Warung Jus
A Neobrutalist Point of Sale (POS) and real-time sales reporting system designed for local juice vendors, featuring order processing, transaction logging, and QRIS payment integration.
Core Tech Stack
Project Goal
Warung Jus was developed to digitalize cash registry operations for micro-merchants and street food vendors. The primary objective was to replace slow manual ledger logs with an interactive, responsive Neobrutalist-styled POS dashboard that allows vendors to process orders, manage menu lists, customize QRIS static dynamic receipts, and monitor daily revenue trends instantly on mobile or tablet devices.
Engineering Challenges
The critical challenge lay in ensuring complete offline resilience for order logging while maintaining high UI responsiveness. Additionally, generating instant local dynamic QRIS codes in compliance with Indonesian payment regulations required robust client-side canvas render loops and string formatting controls.
Key Technical Achievements
- Built a high-performance offline-first local cache synchronization bridge for seamless POS data storage during network drops.
- Crafted a fully responsive Neobrutalist dashboard using Tailwind CSS and Framer Motion, optimized for mobile cashier layouts.
- Developed an dynamic menu analytics logger visualizing high-volume sales trends and variant distributions via Recharts.
- Integrated automated QRIS generator layouts mapping static vendor payloads with dynamic price overlays.
