Studio PC / PCBR · 2026–present

Designing a battle royale with no practical skill ceiling

Co-founding and designing an original VR battle royale intended to welcome a new player immediately while continuing to reward mastery after thousands of hours.

Current venture / 2026

Turning competitive insight into game design.

PCBR grows directly from years spent studying why certain games remain strategically alive at the highest level. The design goal is not complexity for its own sake, but a dense interaction of movement, aim, positioning, building, information, and decisions that remains understandable moment to moment.

Our development process is deliberately prototype-first. In early Play in Editor tests, we use the minimum implementation needed to validate an interaction's feel, logic, integration, and performance before investing in visual polish.

Design thesis

Accessible immediately. Deep indefinitely.

Simple actions should combine into a decision space with no practical ceiling on mastery.

Current build

An Unreal Engine 5 prototype

Developing the game’s foundational movement, combat, construction, and online-play systems.

My role

Co-founder and game designer

Translating competitive intuition into mechanics, tuning frameworks, documentation, and executable development work.

Development method

Prove the interaction before polishing it

The early weapon wheel looks unfinished by design: first prove that the logic works, the interaction feels right, and performance holds up—then refine the presentation.

AI-native experiments · 2026

Butter—and a different way for one person to build

Using frontier AI as a practical collaborator across research, strategy, software, design, documentation, and operations.

AI-native building / 2026

Compressing the distance between an idea and a working artifact.

Butter is a watch-focused application built as an experiment in turning a product idea into working software with AI as a development partner. The broader experiment is the workflow itself: learning where advanced models can investigate, reason, prototype, critique, and execute alongside a human operator.

Workflow

Many disciplines, one creative loop

Using AI across code, product thinking, research, visual design, writing, and operational systems.

Pavo · Co-founder & Chief Executive · 2017–2022

From painting company to technology platform

Built a real operating business while two product teams developed software and hardware intended to change how the work was sold and performed.

The operating thesis

Build the tools inside the business that had to use them.

Pavo was both a painting company and a proving ground. The service business reached approximately $300K in peak annual revenue and employed 13 people concurrently while I was 20. The larger ambition was to develop a suite of useful products, refine them through daily field use, and eventually combine them with SOPs, branding, and marketing into a franchiseable operating system.

We ran two distinct product efforts at the same time: one team built estimating and proposal software; another developed a pressure-fed paintbrush and its supporting hardware.

Product team 01 / Software

An estimate that became a proposal before leaving the house.

The mobile app captured room measurements, surfaces, finishes, and project details, then turned them into a finished work proposal that could be reviewed with the homeowner during the estimate. It was designed to eliminate hand-typing proposals later and create a better opportunity to close the sale in person.

Product team 02 / Hardware

A pressure-fed system designed to keep working.

Instead of treating the brush as a single disposable object, we separated it into durable and consumable modules. The invention ultimately reached a notice of allowance in the patent process.

Swap without shutting down

Four replaceable layers

The lithium-ion battery pack, paint reservoir, external tubing, and bristle head were all hot-swappable. A fresh battery could charge during use; paint products or colors could be changed without cleaning the entire system; and the premium handle could outlive many sets of bristles.

Paint delivery

Pressure where it was useful

A peristaltic pump was selected for longevity and adequate pressure. Because the backpack reservoir sat above the pump, gravity and negative pressure made priming straightforward. Flexible tubes delivered paint near the bristle tips instead of soaking the ferrule and full length of the brush.

Control at the handle

Built for messy work

A capacitive touch trigger avoided a paint-clogged moving button, while a dial adjusted pump speed and therefore flow rate. LEDs on both sides of the ferrule illuminated cut lines in dark corners and behind fixtures such as toilets.

Electronics & cooling

Two purpose-built control boards

A custom PCB in the handle received user inputs and powered the lights. A second PCB in the backpack controlled the motor and pump. A small laptop fan cooled the motor during sustained use.

Beyond the products

The beginnings of a complete operating system.

The product thesis extended into the details of running and replicating the business: a documented customer process, proposals, color specifications, recruiting, referrals, branded leave-behinds, and even water bottles. Individually they were small artifacts; together they pointed toward a system that another operator could eventually adopt.

Viridi · Founder · 2016

My first venture: indoor gardens for small homes

My first entrepreneurial project: compact, illuminated indoor gardens for people who wanted to grow plants without access to a traditional garden.

First venture / Age 16

Turning a conviction about vertical farming into a physical product.

In 2016, I believed that more agriculture would eventually move indoors. Viridi was my first attempt to make that future tangible: a furniture-like mini garden for apartment residents who did not have outdoor growing space.

We designed the wooden enclosure around rectangular plastic planters and integrated grow lights, then manufactured the units ourselves in my basement with a drill press and circular saw. The project taught me that a product idea becomes much more interesting when you have to make it, price it, and put it in a real room.

The product system

A small garden designed as a complete piece of furniture.

The enclosure, planters, and lighting were designed together so the garden could live inside a small home rather than feel like improvised growing equipment.

User

Growing without a yard

The concept was aimed at apartment residents and anyone who wanted a compact alternative to a conventional garden.

Architecture

Planters, light, and enclosure

Two illuminated growing levels were sized around readily available rectangular planters and packaged in a clean wood frame.

Manufacturing

Built in the basement

A simple shop setup forced us to think concretely about materials, assembly, repeatability, cost, and finish quality.

Competitive Call of Duty · 2012–2015

Learning competition from inside the system

Accumulated 4,600 MLG Pro Points during the Advanced Warfare era and reached approximately the top 250 on MLG’s competitive leaderboard.

MLG Pro Points were the circuit currency of competitive Call of Duty: players earned them through sanctioned competition, and the totals helped determine standings and event seeding.

POPULATION: ONE (Pop1) · JackGPT · 2023–2025

Mastering the whole game, not one role

Reached the global top 20 as a generalist competitor, in-game leader, and systems-focused student of one of VR’s deepest competitive games.

Competitive philosophy

A generalist by design.

I wanted no weak phase of play: movement, aim, weapon fluency, positioning, macro strategy, and leadership all had to hold up at the highest level. Rather than optimize for a narrow role, I trained to become the player who could solve whatever state the match produced.

That same systems view now shapes PCBR: strategic depth comes from the interaction between many individually learnable skills, not from a single dominant mechanic.

Leadership / Communications

Turning the map into a shared language.

As an IGL, I built a hierarchical naming system that let our team communicate locations with far greater precision than a ping. It became one of our clearest competitive advantages, and other teams later began experimenting with similar techniques after hearing the callouts on our streams.

A4B

AStructure family or map area—for example, apartments.

4The specific structure, indexed geographically.

BThe sub-structure, often ordered by relative size.

“Red Hattie, 50 HP, A4B, floor two.”Character, remaining health, exact building, and floor—in a single callout, without requiring a teammate to find a ping.

Weapon & inventory theory

Mechanics mattered most when they changed strategy.

At my peak, I developed world-class mastery of the MK-18, SPR, and TEC-9—not simply for their raw output, but for the strategic options they created.

MK-18

Making a two-handed weapon work one-handed

Its recoil and burst timing made one-handed control extremely difficult. Learning it anyway let me fire over cover while peeking less of my body and preserve its elite far-mid-range damage and build-breaking utility.

TEC-9

A weapon that “bought” an inventory slot

It combined super-close-range time-to-elimination with enough reach for head peeks and close-mid-range fights. Covering the jobs of both shotgun and SMG created room for another health item.

SPR

Converting a balance window into an advantage

Before it was later nerfed, the SPR offered exceptional sniper output. I invested heavily in mastering it while that strategic window existed.

Deliberate practice

Training my brain like a learning system.

I treated difficult mechanics as learnable functions rather than fixed talents. If a behavior was physically possible, I trusted that enough high-quality signal and systematic practice could teach my brain to approximate it.

Data quality meant engineering the training environment—not simply reviewing matches. Cannon and I built custom maps to isolate individual skills, then spent most of our hours in 1v1, 2v2, and 3v3 team deathmatch against the best players in the world. High-Elo solo queue added a different challenge: winning against coordinated teams while paired with weaker random teammates demanded better positioning and more strategic fights.

01Data diversityCombine isolated drills, elite custom matches, and unpredictable solo queue.

02Training scaleUse repeatable environments to produce far more useful repetitions per hour.

03Data qualityConcentrate practice on the exact skill being learned and the strongest opposition available.

04RecoverySupport learning with excellent sleep, diet, and exercise.

Current focus

Building PCBR—and learning how much leverage one person can gain from AI.

PCBR is an original VR battle royale built around a demanding design goal: easy for a new player to enjoy, with no practical ceiling on mastery. I am developing it with my co-founder through Studio PC.

In parallel, I am developing an AI-native way of working. I use advanced models as collaborators across disciplines—not simply to generate text, but to investigate, reason, prototype, critique, and execute at a speed that would previously have required a much larger team.

This site was designed, written, built, and deployed with AI in one evening.
