Mid-level XR Developer specializing in healthcare training simulations

6y exp

“XR Developer II at Orbis Education building multiplayer healthcare training simulations in Unity/C#. Shipped cross-platform experiences on Meta Quest 3 and iPad, including a new oxygen mask/tube simulation system that increased student engagement and learning feedback. Also built a capstone generative-AI patient interaction system replacing IBM Watson with an Ollama-based approach, evaluating cloud vs. self-hosting for latency/cost/reliability.”

“Unity/VR engineer with nearly 15 years of experience, specializing in multiplayer architecture, cross-platform systems, and developer tooling. He built and shipped a reusable Unity Netcode-based multiplayer stack with authentication, matchmaking, Vivox voice chat, and custom host migration that reportedly improved development speed by 70% to 80%, and has also supported releases across Meta Quest, consoles, and mobile-related ecosystems.”

“Unity VR developer with hands-on experience shipping and optimizing standalone builds for Meta Quest (and PICO). Led gameplay + networking on a Quest 3 multiplayer social VR experience (real-time sync, avatars/gestures, proximity voice), and also built a mostly solo game that blends fast-paced restaurant simulation with a night-time horror/stealth loop featuring custom AI.”

“Built and productionized an LLM-enhanced version of the WeDAA platform to auto-generate microservice architecture diagrams and support code generation from user prompts, including a practical solution for non-overlapping canvas object placement via coordinate templates. Experienced in diagnosing agentic workflow failures using AWS Strands agents with feature-flagged debug logging, and frequently supports sales through tailored demos and POCs to drive adoption.”

“Unity/C# developer with hands-on Meta Quest shipping experience from Wren Kitchens, building a VR kitchen scale visualiser and solving tricky URP/HDRP cross-pipeline rendering issues by creating internal shader/asset management utilities. Also has solo Unity game experience including an Android/Google Play release and game jam prototyping, plus side-project work using Python/PyTorch for predictive modeling.”

“Frontend-focused engineer with full-stack capability (Node/Express + MongoDB/MySQL) who emphasizes scalable quality practices: PR-driven reviews, CI quality gates, and a full testing pyramid (Jest/Vitest, React Testing Library, Cypress/Playwright). Built complex React + TypeScript role-based dashboards/workflows using reusable component architecture and layered state management (React Query/SWR, Context for auth/roles), with strong performance and UX polish (Lighthouse, lazy loading, accessibility, responsive design).”

Remote, USA4y exp

“Backend/full-stack engineer with experience building customer-facing contact-center automation (agent assignment) and internal editorial/data operations APIs for life-sciences ontology management. Strong in microservices and event-driven systems (Spring Boot + Kafka), third-party integrations (Genesys/Five9), and pragmatic iteration via MVP scoping, tight stakeholder demos, and observability-focused reliability.”

Mid-Level Game Designer specializing in Level Design and Unreal Engine

4y exp

“Unity/VR game designer with shipped Meta Quest experience across two titles, including a lite-sim/arcade multiplayer project and a Sniper Elite VR standalone DLC where they built the "Last Stand" mode and balanced wave/drop systems. Currently building a solo prototype featuring Pikmin/Overlord-style rat horde control mechanics, using AI and community resources to upskill in programming and debug Unity physics.”

“Built a production ad-spend optimization system that combined deterministic audit logic with LLM-generated explanations, surfacing severe inefficiencies including 70-90% wasted spend in some Google Ads accounts. Stands out for pairing measurable business impact with pragmatic AI safety and usability decisions, including approval-gated execution and structured, human-readable recommendations.”

“Unity/VR developer who has shipped games for Meta Quest and built a game (Remix Heroes) largely solo, handling everything from game design and UX/UI to level backgrounds, gameplay, and backend networking features like social events and leaderboards. Experienced with Quest 2/Quest 3 testing and uses AI tools to review system designs and evaluate solution options.”

“Frontend engineer with ~6 years of experience delivering SEO- and performance-sensitive web apps (e.g., an automobile sales platform built with Next.js SSR) and complex React+TypeScript dashboards for energy management/heat pump scheduling. Has handled real-time data challenges by integrating MQTT, and combines hands-on frontend ownership with Agile team coordination (standups, task assignment, client demos, requirements).”

“Built and shipped production AI search and RAG features for a university portal, including an embeddings-based semantic search layer and a documentation-grounded assistant with citations and anti-hallucination prompting. Also developed scalable, reliable data pipelines integrating Google Ads/GA4/Meta APIs for automated reporting, with strong focus on evaluation loops and retrieval quality improvements (hybrid search, chunking, query-log driven iteration).”

“Candidate is actively using AI-assisted development tools, including MCP server integrations with Copilot, to generate boilerplate test scripts, validate code standards, and handle package updates. They also have hands-on experience choosing different agents based on task requirements and serving as an admin for AI tool access.”

“Full-stack engineer who has shipped and operated generative-AI chat/QA features end-to-end, including a RAG-based pipeline with guardrails and cost/latency monitoring in production. Experienced with React/TypeScript + Node/Postgres architectures, Dockerized deployments to AWS (EC2) via GitHub Actions CI/CD, and building reliable ingestion/ETL systems with idempotency, backfills, and reconciliation.”

“Game QA professional with AAA open-world shipping experience, owning high-impact quality risks like save-data corruption, progression blockers, performance drops, and multiplayer desync. Demonstrates strong systems thinking and exploit prevention (e.g., reproduced and helped fix a reward-duplication race condition using network interruption + rapid input), with disciplined JIRA/TestRail workflows and evidence-driven bug reporting.”

“Software engineer who built an AI marketing/outreach agent end-to-end: Next.js (App Router + TypeScript) frontend integrated with a Python/Django REST backend using LLMs (Gemini, ChatGPT-4o) and SQL databases. Demonstrated measurable performance wins—improved a 100k-record UI by 15% (Lighthouse) and cut a Postgres-backed search API from ~3s to ~1ms via indexing—while also owning post-launch monitoring (webhooks/cron, New Relic/CloudWatch) and customer support.”
