About Me

Hello! My name is Janitha and I'm an Electrical & Electronics Engineer passionate about IoT, Edge Computing, and Backend Systems. I specialize in building production-level systems that bridge the gap between hardware and software.

I have hands-on experience with IoT gateways, edge devices, and backend integrations. I've built production-level IoT gateways using Java with serial communication, MQTT data publishing, local SQLite storage, and multi-threaded processing. I've also worked with NVIDIA Jetson platforms to run ML models for real-world edge applications.

Here are a few technologies I've been working with recently:

  • ▹ C
  • ▹ Python
  • ▹ Java
  • ▹ JavaScript
  • ▹ Arduino
  • ▹ NVIDIA Jetson
  • ▹ Linux
  • ▹ MQTT
  • ▹ FastAPI
  • ▹ SQLite
  • ▹ Spring Boot
  • ▹ TensorFlow
