What I build

Deep specialization at the intersection of AI, distributed systems, and blockchain infrastructure.

AI/ML Infrastructure

End-to-end ML pipelines from data curation through fine-tuning to quantized local deployment. Multi-provider fallback architectures for production reliability.

LLM Fine-Tuning GGUF Ollama RAG MCP MLX

Distributed Systems

Decentralized GPU inference benchmarking, video processing pipelines, and edge compute architectures. Performance-critical Rust services.

GPU Inference Benchmarking Video Pipelines Edge Compute Rust

Blockchain / Solana

Air-gapped cold wallets, DCA trading bots, cross-chain DeFi research, and on-chain attestation systems. Secure key management in Rust.

Solana Ed25519 Jupiter API DeFi Cold Wallets

Developer Tools

CLI toolkit suites, MCP servers for AI orchestration, CI/CD pipelines, and deployment automation across Cloudflare and GitHub Actions.

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.

Why I'm Building AI Developer Tools

The next wave of developer productivity isn't about writing code faster. It's about AI that understands your entire codebase and can act on it. MCP is the protocol that makes this real.

The MCP Protocol: Why It Matters

Model Context Protocol is quietly becoming the standard for AI-to-software integration. I've built 5+ servers on it and here's what I've learned about production MCP development.

Coldstar: Rethinking Cold Storage

Why I built a USB-based cold wallet that keeps keys in RAM only during signing — and what it taught me about security UX and Rust memory protection.
