Hi, I'm Tima

Maintainer/contributor around agent tooling and multi-channel assistant workflows. I focus on practical engineering: issue reproduction, real behavior testing, and shipping fixes that survive production traffic. Recent work includes MiniRouter routing/eval infrastructure and competition tooling.

🚀 Start Here

mini-router/minirouter - Gittensor miner workspace for MiniRouter: routing trainer/eval code, benchmarks, submissions, and the web competition site
touchpilot/touchpilot - Automation and control workflow experiments
openclaw/openclaw - Personal AI assistant across CLI, WebUI, Slack, Telegram, Discord, Matrix
infiniflow/ragflow - RAG engine: Go driver implementations and provider integrations
langgenius/dify - LLMOps platform: EnumText type-tightening sweep across the API
