Game Systems Architect | Senior Unity Developer | Web3 + NFT + Multiplayer Expert
I’m Charles Walls, a Senior Unity Game Systems & UI Engineer with over 9 years of experience creating immersive, high-performance games for web, mobile, and VR platforms. I specialize in architecting complex metagame ecosystems and NFT-driven features, building robust UI systems, and optimizing Unity-based performance for smooth 60 FPS gameplay across devices.
I’ve led teams and shipped games played by millions, including Mushro Legends, where I implemented scalable systems like Deck Editing, Battle Pass, and a Web3 NFT Store that processed 500k+ trades. My work increased retention by 45% and drove over $3.5M in revenue. I'm also skilled in Unity’s DOTS, Addressables, custom shaders, and Web3.js integrations with Ethereum smart contracts.
Whether it's real-time multiplayer with Beamable, backend logic with Firebase and DynamoDB, or crafting dynamic UI with Unity’s UI Toolkit, I deliver polished, engaging user experiences. I love working remotely, collaborating across disciplines, and mentoring dev teams to elevate game quality and system efficiency.
Let’s build something epic together.
Work Terms
I operate Monday to Friday from 8 AM to 7 PM CST, with flexible availability for critical updates or meetings. I prefer clear, asynchronous communication via Slack, Discord, or your preferred messaging platform, with regular check-ins and milestone-based updates.
Payment terms are typically on a weekly or milestone basis via Guru’s SafePay. I'm happy to adjust depending on the project scope and timeline. I believe in transparency, high code quality, and delivering results that exceed expectations.
