RACHMAWAN
Bridging the gap between physical hardware, embedded silicon, and high-performance game engines. Specializing in C++, custom SDK development, and real-time device communication.
ABOUT THE ENGINEER
Specializing in hardware-software interface development & cross-platform engine integrations.
Focused on writing clean, deterministic, and maintainable low-level code that bridges the physical world with interactive software. With deep expertise across C++, Embedded Systems, and Game SDKs, I solve cross-platform compatibility challenges, optimize memory/throughput bottlenecks, and build tooling developers love using.

FEATURED SHIPMENTS
QR Vending Machine
Developed a general purpose vending machine kotlin-based app with QRIS payment support. Customers could choose what kind of vending machine they’ll be using for their product, either item based or service based product. This app could communicate with hardware systems to support the vending feature.
Remote Ignition System App and Device
Developed a remote ignition system utilizing the LoRa network. The ignition could be triggered from the VB-based app.
Room Monitoring App and Device
Developed a room monitoring system using temperature sensor, humidity sensor and fire detector to monitor room condition. The result could be monitored from an flutter-based Android app streamed from Firebase real time database.
