“Unity generalist with VR-focused optimization experience who replaced a bloated third-party IK/rigging plugin by building a custom DOTS/Burst multithreaded system, reporting ~200% performance gains and a noticeably smoother VR experience. Has multiplayer experience with Unity Netcode (and some Photon Fusion exposure) and uses AI tooling (Rider AI) to speed up refactoring and documentation.”

“Unity/C# tech lead specializing in multiplayer systems and networking reliability: built a transaction/prediction-based multiplayer inventory system using snapshots/deltas that eliminated duping and supports very large item transfers via RPC. Also implemented an LLM-driven localization pipeline (SGLang on DGX Spark with Gemma Translate) with automatic OpenAI fallback and human QA, and has shipped VR work on Meta Quest 3 with cross-platform input abstraction (mobile/VR/web).”

“Unity developer (3+ years) focused on mobile multiplayer/casual games, combining technical leadership with game design ownership. Has shipped modular gameplay systems, integrated monetization/analytics, and built a custom Unity Editor plugin for configurable combat/animation montage workflows (masking + blending). Not experienced with VR/Meta Quest yet.”

“Unity game developer with a standout gameplay-design contribution: proposed and implemented an early merge-to-upgrade mechanic (halving unit count to increase strength) that became foundational to a successful merge battle/merge dragons-style game. Has multiplayer/VR mod experience and is currently learning Unity Netcode for GameObjects, with confidence switching to Photon Fusion. Also applies AI workflows for maintainable coding and rapid mobile icon/banner prototyping to support A/B testing and CPI optimization.”

Junior Full-Stack Java Developer specializing in FinTech microservices

OH, USA3y exp

“Full-stack engineer with production experience building a real-time order tracking system using React + Firebase/Firestore, emphasizing audit-friendly data modeling, state-machine-based status transitions, and strong post-launch ownership (performance, security rules, reliability). Demonstrated measurable frontend performance gains by isolating real-time updates to dynamic components and applying memoization, plus backend reliability patterns (idempotency, retries) and SQL query/index optimization validated with EXPLAIN ANALYZE.”

“Lead developer on PoolLiveTourMax who owned core gameplay, physics, backend services, and end-to-end multiplayer architecture. Brings a strong blend of Unity gameplay engineering and backend/networking expertise, including server-authoritative netcode, dedicated server deployment, and performance optimization for memory, FPS, and latency.”

“Software/product engineer who owns customer-facing internal platforms end-to-end, with deep experience building data pipeline health and data quality tooling (near-real-time alerting and ops dashboards). Strong in React/TypeScript + Python REST architectures and microservices with RabbitMQ, emphasizing reliability patterns (idempotency, DLQs, correlation IDs) and fast, safe iteration via feature flags, testing, and observability.”

“Unity/C# developer who built a non-AR prototype feature for an AR hide-and-seek game that became a preferred gameplay mode: smooth touch-driven camera orbit and zoom without image distortion. Demonstrates practical camera/FOV tuning and player-experience-driven iteration; has introductory exposure to Photon Fusion concepts (C# attribute-marked network methods).”

“Backend engineer who owned the API layer for an AI trust/analytics dashboard (trust scores, stability checks, public verification endpoints) using Python/FastAPI and Postgres. Has hands-on DevOps experience deploying FastAPI and Node.js services to AWS Kubernetes with GitHub Actions + ArgoCD GitOps, plus Kafka-based real-time event streaming and careful staged migration practices (shadow traffic/dual writes, rollback planning).”

USA3y exp

“Backend-leaning full-stack engineer in fintech/payments who shipped an end-to-end Stripe payments + webhook system for a financial microservices platform, emphasizing ledger accuracy via idempotency, transactional writes, retries, and DLQs. Also delivered a real-time React/TypeScript payment status dashboard informed by user interviews, and improved production performance by 35% p95 latency through PostgreSQL tuning and Redis caching on AWS.”

“Unity developer with shipped Meta Quest 2 room-scale VR experience, owning VR architecture (XR Interaction Toolkit/Oculus Integration), core interaction systems (grabbing/UI/locomotion), and Quest performance optimization. Also built a solo mobile puzzle game with star-based difficulty tuning, UI/performance profiling, and progression/replay systems, and uses AI assistants to speed prototyping, debugging, and documentation.”

“Unity game developer with hands-on gameplay AI experience (FSM-driven monsters with customized NavMeshAgent movement) focused on creating readable, high-tension survival encounters through iterative tuning. Has shipped/created 4 Unity games solo end-to-end (UI, animations, architecture, state machines) and has also built a full Python game server; some exposure to Photon Fusion and strong client/server REST API implementation experience.”

“Frontend engineer at LodestonePM who led end-to-end delivery of an AI release-notes generator (OpenAI API) and a Kanban-style release board in Remix/React/TypeScript. Demonstrated scalable architecture (bridging tables, upserts), strong QA practices, and measurable performance wins (200+ item loads reduced from 10–20s to a few seconds via caching/pagination), plus UX improvements like simplifying a Jira integration flow.”

“Backend/platform engineer who has owned FastAPI microservices for analytics/ML ingestion and driven measurable performance gains (cut latency ~40%).
