Hi, I'm Johirul Islam, currently working as a doctoral researcher at the University of Oulu, Finland. As a doctoral researcher, by accommodating the extreme-edge local computing cluster, I am trying to reshape the traditional 2-tier edge-cloud into a 3-tier computing architecture for building a smart hospital environment. 

During my doctoral research, I have had the chance to play with various RTOS-based IoT devices (e.g., RPi Pico, ESP32, Arduino Nano, etc.) and GPOS-based IoT devices (e.g., RPi 3, RPi 4, RPi 5, etc.) to build and deploy the required services. I also utilized Nvidia GPU resources (e.g., Jetson Xavier NX Dev Kit & Clara AGX) for developing demos and PoCs for medical-use-case services. The services are deployed into a 3-tier architecture, considering extreme-edge nodes as tier-1 while MEC-based nodes and Cloud nodes are considered tier-2 and tier-3, respectively. 

I build things from scratch with my strong knowledge of Linux, Docker, Kubernetes, and cloud-native tools. I don't just deploy the required services; I set up bare-metal Kubernetes clusters, write custom automation, and dig into the underlying system until things work the way they should. That same instinct is now driving my transition into AI/ML—building pipelines, understanding the stack end-to-end, and bridging the gap between infrastructure and intelligent systems.

Currently, I am expanding my knowledge into generative AI while continuing to deepen my infrastructure expertise—because the best AI/ML systems are only as good as the infrastructure they run on.
