About
Matthew Karsten
AI/ML engineer and distributed systems builder. Founder of Purple Squirrel Media.
I've spent 5+ years at the intersection of AI infrastructure, distributed systems, and blockchain. I build things that work in production — from LLM fine-tuning pipelines to air-gapped hardware wallets.
My research on decentralized GPU inference showed a 47% cost reduction versus centralized cloud. I train models locally on Apple Silicon, publish them on Hugging Face, and ship quantized endpoints for local deployment. Everything is MIT licensed and open source.
I write Python, Rust, TypeScript, Go, and Ruby. I've built MCP servers, CLI toolkits, DCA trading bots, and 7-crate Rust video players. I work best on hard infrastructure problems.
