Performance direction

Tone, timing, trust, and restraint — applied to synthetic voices.

AI-native building

Agent loops, eval rubrics, and workflow harnesses, hands-on.

20+ years VO

Commercial, promo, narration, animation, games, and enterprise — under real pressure.

Amsterdam-based

Local to the Netherlands and EU teams — same time zone, no fly-in friction.

Building with AI

Codex, Claude Code, agent loops, and workflow harnesses — hands on the tools.

The problem

Better voice AI still needs better direction.

The models are getting astonishingly good. But in the real world, voice systems still live or die on human details: trust, timing, tone, emotional restraint, brand fit, escalation, and whether the customer actually wants to keep listening.

The model can speak. But can it land?

Naturalness, emotional timing, authority, and restraint — the difference between impressive and believable.

The agent can answer. But does the customer trust it?

Escalation, interruptions, empathy, and clarity decide whether a caller keeps listening or hangs up.

The demo works once. But can the team repeat it?

Evaluation loops, scripts, and QA harnesses turn a lucky take into a reliable, reusable workflow.

The voice sounds real. But is it directed?

Performance direction applied to AI voices — the same craft that makes a human read land.

Why CJ

A performer's ear. A director's eye. An AI builder's hands.

CJ sits in the narrow overlap between professional voice performance, performance direction, and hands-on AI workflow building — the rare combination voice AI teams rarely find in one person.

Professional voice performance

  • 20+ years as a working voice actor across commercial, promo, narration, animation, games, corporate, and e-learning.
  • Credits include Coca-Cola, Apple, Disney, The Last of Us, and Resident Evil 6.
  • Knows what makes a voice feel bought-in, human, and usable under production pressure.

Performance direction

  • Diagnoses tone, pacing, emotional truth, authority, warmth, and clarity.
  • Directs actors, executives, non-actors — and synthetic voices — toward better outcomes.
  • Brings studio judgment to model outputs, voice agents, demos, and scripts.

AI-native workflow building

  • Actively building with Codex, Claude Code, agent loops, workflow harnesses, and automation.
  • Turns fuzzy problems into prototypes, rubrics, evaluation loops, and operational systems.
  • Speaks both creative/performance and technical/product language.

How CJ helps

Where the human layer creates leverage.

Booked individually or combined — evaluation, demo design, direction, and workflow prototyping, scoped to the model, the team, and the customer-facing stakes.

Voice-agent evaluation

Rubrics for naturalness, trust, pacing, persona fit, escalation, pronunciation, and interruption handling.

Enterprise demo design

Scripts, scenarios, persona design, voice choices, and narrative framing for customer-ready demos.

Performance direction for synthetic voices

Human-quality notes for generated speech: where it feels real, where it breaks, and how to improve it.

Creative workflow prototyping

Fast experiments for social, creator, product marketing, localization, and AI content production.

Agent workflow / harness building

Lightweight systems for testing prompts, voices, scenarios, QA passes, and repeatable deployment patterns.

Amsterdam / Netherlands bridge

Local availability for Netherlands teams, EU customers, studios, agencies, and enterprise conversations.

A timely fit

Especially relevant as voice AI moves into the Netherlands.

As voice AI companies build teams around deployment, solutions engineering, creative production, and internal AI transformation, CJ brings a rare combination: the judgment of a working voice performer, the instincts of a director, and the practical curiosity of an AI-native builder.

Companies building voice AI in the Netherlands need more than engineering and sales. They need people who can help enterprise customers understand what good sounds like, where voice agents create value, and how to make AI speech feel trustworthy in the real world.

  • Internal AI systems & process automation

The rubric

What CJ listens for.

The point is not whether the voice sounds “real.” The point is whether it works — for the customer, the brand, and the team that has to ship it.
