  • Proven ability to design, ship, and scale LLM-powered applications.

  • Expertise in API design, streaming, and CI/CD pipelines.

  • Track record of building reliable systems with measurable performance and error budgets.

Key Results (First 90 Days)
  • Audit current cross-agent flows for UI/UX cohesion.

  • Implement shared components and typed contracts for reliability.
