Rafael Z.

I've spent 8 years building and shipping Unity games and mobile apps on Android and iOS: 15+ titles shipped and serviced, 1M+ downloads across the apps I've worked on, and live ops for apps with 70k+ combined monthly active users.

WHAT I'M USUALLY BROUGHT IN FOR

• Mobile UI/UX that works but doesn't feel right. I've taken full ownership of the UI/UX on live apps, including enterprise apps, natively on Android and iOS.
• Leading Unity 2D and 3D games and apps from prototype to long-term live service: architecture, gameplay systems, monetization, and live ops.
• Real-time multiplayer: Photon Fusion, network-synced physics, PlayFab and Azure Functions backends.
• Performance on mid- and low-end phones: profiling, draw calls, memory, load times.
• Inherited or stalled projects that need someone to take ownership and ship.

SELECTED WORK

• Off-Road Champion: led development of a 3D racing game past 500k downloads. Built the multiplayer mode, adapted vehicle physics for network sync, integrated analytics, ad mediation, attribution and push.
• Anatomist: anatomy and pathology learning app. Reworked the interface, auth and backend; 35k monthly active users.
• MORPG prototype: 6 months on a scalable online game. Addressables streaming, PlayFab + Azure Functions for auth, profiles and economy, Photon Fusion 2 for players, AI enemies, synced combat and chat. Desktop, mobile and WebGL.
• Space Box: real-time multiplayer battle arena with modular ship building.
• Current project: a dark storybook mystery/horror game in Unity 6 / URP. Custom cel shader, compute-shader volumetric fog, 80k-particle GPU mesh morphing, motion matching.

Genres shipped: physics shooters and puzzles, board and word games, 2.5D roguelike, 3D racing, runners, third-person, real-time multiplayer.

MOBILE PRODUCTION
KPI-driven development, ad systems and mediation (AppLovin MAX, AdMob, Unity Ads), attribution (Kochava), analytics (Firebase GA4, Unity Analytics, DevToDev), A/B/C testing, store releases, staged rollouts, crash triage.

SAAS AND AI
I also build full-stack SaaS, including a product I designed and built solo: retrieval-augmented generation, multimodal embeddings, a tool-calling agent on Claude via AWS Bedrock, human-in-the-loop editing. I use AI tooling in client work where it speeds delivery up, with the same code review standards.
