Open to both short/long-term contract or a full-time position if the chemistry is there.

I fluctuate between:

- Deep learning / Neural networks - from architecture to inference. You might have used my ♥ Lovely Tensors library if you work with PyTorch (or JAX). CUDA, pytorch profiler, etc.

https://github.com/xl0/lovely-tensors https://github.com/xl0/lovely-jax https://github.com/xl0/lovely-numpy

https://github.com/xl0/tidygrad - autograd from scratch https://github.com/xl0/latent-tools https://github.com/xl0/nvml-tool - manage nvidia CPU fans/power

- Full-stack AI-adjacent applications - the usual LLM API tool-calling agentinc AI + full-stack, ideally with SvelteKit.

I really got into Pi recently. Some cool stuff: https://github.com/xl0/pi-lovely-ide if you like to interact with the code. Check linked projects from there.

https://www.npmjs.com/package/grok-mermaid - 1.5M weekly downloads.

In my past lives: Linux kernel, Molecular Biology Masters degree, Electronics engineering in Shenzhen.

xl0··on Pelican: Multi-step SVG generation with vLLMs
LLMs can use feedback and progressively improve their output. Pelican lets an LLM generate SVG / ASCII art, sends the rendered image back to the model to improve it on the next step. Open-source and BYOK (not shared with me), give it a try.
