nathanrenting.dev
Available · 2-3 days/week contract (ZZP, NL)

Solo dev with an audio background. Agent systems, real-time audio, and the engineering underneath.

Twelve years in entertainment and audio production first, then increasingly serious on solo engineering. Now building agent orchestration, audio engines, and the supporting infrastructure. Solo, AI-augmented, from Eindhoven (NL).

What I do

  • Agent systems & multi-agent orchestration. Tool-dispatch, vault-backed memory, agentskills.io-compatible workflow layer (OpenClaw-compatible), three-tier AI fallback. Native to the Anthropic Claude stack.
  • Real-time audio engines. Rust + FFI, lock-free SPSC ring buffers, allocation-free audio paths, cross-platform Android (NDK). 10+ years background as an audio producer.
  • EU-first infrastructure. Supabase EU-Frankfurt, Sentry EU, GDPR-by-design data flows, DPA-chain discipline, Verwerkingsregister maintenance.
  • Cross-platform mobile. React Native + Expo, Android NDK with native code, cross-architecture builds (arm64 / armv7 / x86_64).
