CoderMitchell
Complex problems.
Clean solutions.
Real scale.
I'm Mitchell — a software engineer and game developer. I've cofounded content studios, led teams, shipped hundreds of products across Minecraft and Roblox, and built the backend systems behind games with 1.5M+ concurrent players. Now I'm building independently.
Real products. Real players. Real scale.
Products I've built, scaled, and operated — from zero to millions of players and millions in revenue.

Things I've learned building at scale.
Technical writing on distributed systems, live-service engineering, and lessons from operating products with millions of players.
The Types of Tools You're Missing
A framework for spotting the internal tools most live games are missing, from aggregation and correlation surfaces to workflow and decision tools that reduce operational drag.
Read →How AI Made DataStore Version Forensics Practical
How AI-assisted toolbuilding turned DataStore version history from a theoretically powerful investigation method into something practical enough to use routinely for profile integrity, security review, and incident reconstruction.
Read →How I Receive and Process Roblox Commerce Refund Events
A walkthrough of the refund pipeline behind Roblox commerce products: signed webhook verification, idempotent order processing, per-user queueing, DataStore-backed clawback delivery, and exact in-game removal keyed to the original purchase receipt.
Read →DataStore Write Correctness: Handling Timeout-But-Committed Operations
Why the common "try the write, refund on failure" pattern in Roblox DataStore produces incorrect state — and the correct approach using cache-bypassed verification reads.
Read →ProcessReceipt and the Two-State Problem
Why Roblox's two-state ProcessReceipt contract creates unresolvable failure modes where developer products cannot handle permanently invalid purchases — and what the API needs to fix it.

I'm open to the right conversations — whether that's engineering for a live product, systems design, a technical partnership, or something I haven't considered yet.
