I'm building a studioand the system behind it.

Haunted Game Studio is where the work ships. MACK is the control plane I'm building to make a growing team of specialist agents repeatable, reviewable, and safe to direct.

The headliners

One makes the work real. The other makes it repeatable.

Haunted Game Studio

A real studio, built in public where it counts.

I use a working game studio as the proving ground for agentic delivery: design, engineering, builds, testing, launch operations, audio, art, and the systems connecting them.

Shipped

Mushrooms vs Skulls is live on Android.

Released under Haunted Game Studio, with iOS work still ahead. A product people can install is a stronger claim than a polished agent demo.

Master Agent Control Kiosk

MACK is the studio control plane I'm designing: one place to direct specialist agents, expose the state of a game, enforce handoffs, and keep the human Director in control.

This is the system being built, not a fake operations dashboard. The studio's current agents and tools exist; MACK is the layer intended to coordinate them.

Operating practice

The interesting part is not that the agents can code.

01

Parallel work, isolated branches

Agents work concurrently in separate worktrees. Their branches return one at a time for deliberate review and merge.

02

Human-only authority

Credentials, production accounts, live domains, and real spend stop with me. That boundary is part of the architecture.

03

Evidence closes the loop

A passing-looking result is not enough. I read the diff, run the checks, inspect the output, and keep failed gates visible.

Pressure test

Perimeter-Cerberus made guessing visible.

A game built against 356 frozen design contracts. When a value was missing, the agents had to expose the gap instead of filling it with something plausible. Twenty-six sprints, a Windows build, an Android APK, and two registers of what the contracts got wrong.

Inspect the engineering record

1,569 tests

The frozen v1 baseline passes.

CI runs the same suite on Linux, Windows, and macOS. It is a baseline for the next build, not a claim that the next build is done.

2 / 18 gates

Pending means pending.

The remaining release gates stay visible instead of being deferred out of sight to make the project look further along.

Evidence, now

The archive

The prototypes had names. The lessons stayed.

Foundry

An earlier operating-layer concept that clarified durable workflows, explicit authority, checkpoints, and provider boundaries.

Open the old workshop

Atlas

The governance experiment that taught me enforcement belongs in task shape and validated state, not reassuring prompt language.

Browse the design record

The operator behind it

15+ years building software. 12+ leading the teams that ship it.

My track record is walking into organizations with no durable engineering practice and installing one that lasts. Adopting agentic AI well is the same kind of organizational problem.

6 months

Ad hoc delivery to predictable Scrum

Two teams inside a 20-person cross-functional organization, moved from non-trackable work to a steady cadence.

14 / ~50

Direct reports at peak / managed overall

Across two international teams; personally hired 20+ engineers and owned the full employee lifecycle.

~$1M

Recurring annual licensing eliminated

Architected and built an enterprise HL7 integration platform that replaced CorePoint across all clients.
