Also brings Photon Fusion multiplayer experience with server-authoritative design, client-side prediction, and rollback-safe deterministic gameplay, plus strong cross-functional iteration with designers and artists.”

“Real-time VFX artist specializing in Unity VR/mobile optimization; shipped a Doctor Strange-inspired portal effect for a standalone Meta Quest 2 project ("Projeto Multiverso UNINASSAU") using a custom vertex-offset shader and carefully managed overdraw to hit 50+ FPS. Also building sci-fi VFX (explosions, lasers, environmental effects) for an in-development game ("Star Warfare") and uses AI tools to speed iteration, debugging, and documentation.”

“Frontend engineer who led the Dash Merchant App and Backoffice platform (React/TypeScript/Redux) supporting $50M+ in monthly transactions. Focused on scalable architecture and reliability—introduced typed API layers, centralized error handling, and performance optimizations (including ~40% load-time reduction) while driving team adoption through incremental refactors, templates, and pairing.”

“Frontend lead on a SaaS platform who migrated the product from React/JavaScript to Next.js/TypeScript, improving Web Vitals (including LCP), SEO, and navigation performance. Strong focus on quality and scalability via automated testing and SonarQube quality gates, plus reusable component architecture (e.g., a shared table used across ~20 pages). Built complex analytics dashboards and an AI workflow drag-and-drop canvas UI using React Flow with iterative stakeholder-driven delivery.”

“Unity developer who has built a Meta Quest 3 VR game as a solo developer, handling everything from VR setup and UI to gameplay and builds, including accessibility-focused mechanics for blind users. Also developed the full base-system module for the shipped mobile game "Death Travelers," implementing 30+ rooms with distinct economy and progression functionality (resource conversion, storage, shop).”

“Senior game designer with shipped experience on Outlanders, focused on systems/economy balance, player motivation loops, and clear cross-discipline implementation. Built rapid UE5 prototypes (48-hour cycle) and iterated based on feedback—especially leveraging audio to guide players in an atmospheric horror concept. Has led design decisions under mobile performance constraints, aligning engineering/art/direction to ship a sandbox mode with acceptable entity/map limits.”

“Frontend engineer who leads high-impact refactors and rebuilds end-to-end, including migrating a legacy Next.js frontend to React + Vite and consolidating fragmented styling into a single MUI Joy design system. Has deep experience improving performance and maintainability in complex, data-heavy UIs (orders/financial pages, multi-step editing flows) through modularization, query optimization, and shared context patterns, with strong QA discipline for sensitive financial actions.”

“Unity/VR developer who has shipped a Meta Quest enterprise multiplayer immersive meeting platform (Arthur Spaces) and also delivered a puzzle/quest-style Unity game release in just one month. Leverages AI-assisted Blender workflows to rapidly prototype 3D assets and accelerate MVP development, and is comfortable in both structured studio pipelines and startup-style cross-functional teams.”

“Serial entrepreneur with 30+ years of professional software engineering experience who co-founded Food Truck Stars, initially a food-truck search engine and later pivoted into a catering marketplace to overcome adoption barriers. Validated the model by prototyping at car enthusiast events across the U.S. and turning a profit, using hands-on customer discovery with low-tech, time-constrained operators.”

“Unity VR developer with hands-on experience shipping and optimizing standalone builds for Meta Quest (and PICO).
