About

Hey, I am Justin. I build end-to-end AI and hardware systems, from LLM products and deployment pipelines to embedded robotics and accelerator-oriented compute.

On the software side, I co-founded MediumAI and led R&D from prototype to production, including RAG workflows for multilingual medical documentation. I also experiment with LLM agents, tool use, structured outputs, and serving architectures that make AI systems more reliable and efficient.

On the hardware side, I work across embedded systems, robotics, PCB design, and accelerator design, including Jetson-based computer vision, ROS autonomy stacks, systolic arrays, and attention accelerators.

The common thread in my work is connecting algorithms, infrastructure, and physical compute constraints. I am especially interested in LLM infrastructure, agent systems, robotics, and efficient AI deployment.
