Hi, I'm Umut 👋

📍 Istanbul | 🧩 Builder of systems | 🌐 keltek.ai

I build systems to understand systems. Lately that means the infrastructure under AI agents: routing, memory, and making sure shipped actually means working.

Rust TypeScript Python Swift Go

Building

  • 🔀 Switchback - One Rust binary that routes LLM traffic across providers, with fallback, budgets, and encrypted credentials
  • 🩺 HealthSave Observatory - Your health data on your own machine. Self-hosted, local-first, egress denied by default
  • 🎁 agents-wrapped - Spotify Wrapped for your coding agents. npx agents-wrapped
  • ✂️ JumpCutter - Cuts the silence out of videos. Tauri, Svelte, FFmpeg
  • 🧱 Compound - A local-first control plane for coding agents. Coming soon

Also built SkillAce: role-play simulations that score the soft skills a CV can't show.

Contributing

🤝 I've contributed to Astro, Hoppscotch, headroom, CodexBar, mcporter, oracle, App Store Connect CLI, and more.

Research

  • 🌍 72saat - Offline earthquake copilot for Istanbul's first 72 hours. Kaggle Gemma 4 Good
  • 🎓 LLMs for Game Narrative Design - Master's thesis on generating game quests with fine-tuned LLMs
