Experience

Creator & Lead Engineer — Nitin-AI (open source)

2026 — Present

Rust + Tauri · v0.1.0-beta · Apache-2.0

  • Designed and built a local-first, provider-agnostic AI desktop app across 7 Rust crates with a typed Tauri IPC boundary between a React/TS UI and a trusted Rust core.
  • Implemented a sandboxed agent runtime (workdir jail, per-action approval, auditable log, timeout-kill) and a provider registry unifying Ollama, OpenAI, Anthropic, Gemini, OpenRouter and agent CLIs.
  • Hardened secrets handling: API keys stored in the OS keychain as zeroized leases — never logged or serialized; no server sits in the AI request path.
