Vetted Performance Optimization Professionals

“Unity/VR gameplay engineer who has shipped full games and built a robust coin economy + massive gear customization system (over a million combinations) backed by a cloud service. Notably discovered and fixed a severe backend security flaw by adding proper authentication (security key + OAuth2), and has hands-on VR performance optimization experience (OVR Metrics, LOD/mipmaps, imposters) plus multiplayer sports sync design using Photon PUN2.”

“Performance marketer managing a high-spend B2B SaaS account ($70K–$100K/month) across Meta, LinkedIn, and Google Ads with a full-funnel approach focused on demo/trial quality tied to revenue. Known for disciplined single-variable testing and signal-quality-based budget allocation, delivering a 28% CPA reduction while scaling spend and maintaining conversion efficiency.”

“AI/back-end engineer at Canon who helped build and operate an internal production LLM platform that acts as a secure middle layer between users and models, defending against jailbreaks/prompt injection while enabling RAG, memory, and grounded responses over company data. Experienced with LangChain/LangGraph orchestration, vector DB retrieval, and reliability practices (testing, monitoring, adversarial prompts) to run high-throughput, low-latency AI workflows in production.”

“Built and deployed LLM-powered features for a startup organizational management application, focusing on real-world deployment constraints like latency and cost. Implemented RAG with FAISS and improved retrieval quality by switching embedding models (OpenAI/Hugging Face) and fine-tuning embeddings on medical corpora for a medical-report UI feature. Uses LangChain and LangGraph to orchestrate multi-node LLM API workflows and evaluates systems with metrics like latency, cost per request, and error taxonomy.”

“Lead Unity developer who shipped two public-facing VR projects (Aberwla full release and Cognetic demo) end-to-end to the Meta Quest Store at Animated Technologies, including optimization and VRC compliance. Currently building solo first-person horror/ghost-hunting projects and aiming to ship a small-scope atmospheric title to Steam to broaden platform shipping experience.”

“Unity gameplay/game-flow programmer with ~10 years in the games industry who has shipped on Meta Quest 1 & 2. Built a Steam-available multiplayer "Vampire Survivors"-style co-op demo largely solo in a 6-month contract, handling everything from networking and UI to performance optimization (GPU instancing) and Steam publishing.”

“Frontend engineer experienced leading client-facing portals (including WebGL integrations) and admin panels, with a strong focus on scalable architecture (monorepo, shared design system/atomic design) and performance. Has built complex React+TypeScript workflows like multi-step user creation with dynamic forms, and ships major features (e.g., video recording) using feature-flagged, trunk-based delivery and E2E testing.”

“Frontend engineer who led end-to-end delivery and scaling of an internal HR product (Easy Time), owning architecture decisions (React/TypeScript, Redux Toolkit, Tailwind/shadcn). Experienced building complex dashboard UIs with advanced filters and real-time interactions, collaborating directly with design (Figma) and shipping quickly via incremental delivery and GitLab CI-driven deployments.”

“Frontend engineer who led end-to-end builds for chauffeur/service platforms (Mychauffeur.com, comfydrive.com), implementing Atomic Design architecture with Next.js, MUI, and Redux. Experienced in building React+TypeScript dashboards, improving performance via SSR migration, and shipping high-risk features like MADA payment integration with Cypress-based QA and Sentry monitoring.”
