I'm Dhrubo, a Computer Science graduate specializing in Open Source Software, Intelligent IoT, DevOps/GitOps and Full Stack Development.
I've contributed to TensorFlow’s Raspberry Pi support, authored official Arduino libraries, and worked across embedded systems, self-hosted infrastructure and context-aware intelligent hardware.
As an IT System Administrator and Software Developer, I enjoy building scalable systems that merge hardware and software through automation and smart design.
Founder and lead of an IoT Club, I've mentored students in building practical IoT projects and integrating software with hardware for real world applications.
