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.
