Personal projects/blogs

Hi, my name is Rudrrayan, or Rono - welcome to my site!

I am currently in my second year at the University of Southampton.

I am a self-taught engineer and student. I like low-level, GPUs, and novel accelerator tech.


I got into programming as a kid who loved making games and speedy simulations.

The common thread between all my projects is performance.

After learning more about GPUs (specifically GPGPU programming), I discovered the second dimension of performance – latency and throughput.

I accessed my first GPU in October 2024, my first cluster in March 2025 and my first supercomputer in August 2025.

I’m scaling from performance on single-node programs to seeing how we can reliably scale work to utilise the bandwidth of hundreds of nodes.

I am currently delving deeper into HPC, learning about more niche topics in CUDA, and working on entirely new compute with Groq (now NVIDIA).


Over the years I’ve also played around with cryptography, competitive programming, audio engineering, and some brief stints with webdev.
