Hi, I'm quifox

🤖 Into AI agents, LLM applications, agentic coding, MCP, RAG, and the ecosystem around them.
⚡ I enjoy vibe coding — fast iteration with AI, while still caring about understanding behavior, testing changes, and keeping systems simple.
🔧 Backend-minded. I like turning unclear problems into reproducible bugs and small, verifiable fixes.

AI Agents MCP RAG Vibe Coding TypeScript C# .NET Docker

I spend most of my time exploring how AI changes the way software is built: coding agents, tool use, context engineering, multi-agent workflows, retrieval, evaluation, and the infrastructure around them.

I also care about the less flashy parts — backend reliability, concurrency, caching, data consistency, search quality, and debugging things until the behavior actually makes sense.

Things I like

  • agentic coding and developer tools
  • LLM applications, MCP, tool use, and RAG
  • TypeScript and .NET
  • CLI / TUI tooling and automation
  • backend systems and distributed-system problems
  • open-source debugging and small focused fixes

Simple systems. Explicit behavior. Reproducible results.
