Machine Zone

Full-Stack Developer | Mobile Game Development | Live Ops

Machine Zone (MZ) is known for large-scale, real-time mobile strategy games like Game of War, Mobile Strike, and Final Fantasy XV: A New Empire. During my time there, I worked across front-end and back-end systems, focusing on scalable UI, feature implementation, and live game maintenance for titles with millions of players.

Project Scope & Contributions

I was responsible for full-stack development within a live, large-scale mobile game environment. My work covered everything from in-game features and UI systems to server-side logic, data modeling, and tools used by design and QA teams. I contributed to both new feature development and ongoing content updates, collaborating with engineers, designers, and producers in a high-output environment.

Feature Implementation

I contributed directly to high-impact features that shaped gameplay and player retention.

Highlights:

• Developed front-end and back-end logic for limited-time events, quests, and combat mechanics.

• Built tools to control event timing, player eligibility, and server rewards.

• Optimized feature delivery for low-memory devices without compromising gameplay clarity.

UI/UX Systems

I built and maintained modular UI components that could scale with new features or seasonal content.

Highlights:

• Implemented dynamic UI modules (menus, reward popups, shops) with localization and animation support.

• Built UI pipelines that allowed designers to preview changes without full-engine deployments.

• Ensured consistent UI behavior across multiple resolutions and aspect ratios.

Server-Side Development

I worked on backend logic to support real-time events, player state tracking, and data security.

Highlights:

• Created APIs and backend services for player data management, inventory, and progression.

• Implemented server logic for battle calculations, cooldowns, and reward delivery.

• Maintained uptime and scalability through performance profiling and async task handling.

Tooling & Live Ops Support

I supported the internal team with tools and dashboards to monitor game health and content delivery.

Highlights:

• Developed web-based dashboards for QA and designers to preview and validate live content.

• Built internal tools to test reward flows, localization strings, and content rollout schedules.

• Integrated logging systems to catch server issues and abnormal player behavior in real time.

Testing & Quality

Given the scale of MZ games, I worked closely with QA and automation teams to ensure quality on fast-paced content pipelines.

Highlights:

• Wrote and maintained unit tests for backend logic and API layers.

• Coordinated cross-platform testing (iOS/Android) to avoid regressions during feature rollouts.

• Helped design and validate A/B testing tools for new mechanics and player incentives.
