Game Developer • Systems • Levels • Prototyping

I create playable systems that feel great from moment one.

I build clear mechanics, juicy feedback, and readable levels—then iterate fast with playtests.

Process

A simple loop that keeps decisions grounded in player behavior.

01

Define the player promise

What fantasy are we delivering, and what do players do minute-to-minute?

02

Prototype fast

Greybox mechanics and levels, prioritize feel, then validate direction early.

03

Playtest & tune

Observe, measure, iterate. Clarity first, depth second, mastery last.

What you’ll see in my case studies

Goals → constraints → iterations → outcomes (with gifs/videos if available).

“If the player can’t read it, they can’t enjoy it.”
