Hardware manufacturers, medical device companies, warehouse barcode/RFID platforms, and robotics educators building zero-install browser configuration and telemetry portals frequently search to hire a freelance WebUSB, WebSerial, WebHID & WebBluetooth (BLE) programmer. I am Aldian Fazrihady, a Senior Freelance Full Stack & Hardware-Web Integration Programmer.

Core Browser-to-Hardware Communication Capabilities

  • WebBluetooth (GATT Services & Characteristics): Connecting Chrome/Edge/Android browsers directly to BLE medical wearables, fitness sensors, smart locks, and industrial gauges with automatic packet framing and CRC verification.
  • WebSerial & WebUSB Firmware Flashing & Diagnostics: Building browser-based ESP32 / STM32 / Arduino / custom PCB firmware updaters (DFU), serial console plotters, and ESC/POS receipt/label printer drivers (`ZPL` / Zebra).
  • Web Workers & Ring-Buffer Binary Parsing: Processing high-frequency binary sensor streams in dedicated Web Workers so 60 FPS React oscilloscope/telemetry charts never drop a frame.

Frequently Asked Questions

Can our customers configure and update our USB/Bluetooth hardware directly from a Chrome browser without installing Windows/macOS drivers?

Yes! Using WebUSB, WebSerial, and WebBluetooth over HTTPS, users can pair devices, stream live diagnostics, and flash firmware updates directly from your React web application.

How do I hire you for WebUSB, WebSerial, or WebBluetooth engineering?

Hire me via Upwork.
