Principal Engineer - Applied AI and Game Systems

Twenty years shipping production software, most of it real-time systems in games and simulation, now applied to AI products. I built and shipped GamePrompt, which turns a written description into a playable Godot build and verifies every one compiles and runs. Before that I was the technical escalation point at Originator (Spin Master): I owned the Coloring activity in PAW Patrol: The Game from design through its worldwide iOS and Android release, and built a child-safe LLM story experience with generative voice that two independent red teams could not break. Earlier I published up to 100 mobile games with 20M+ downloads, led client architecture on a server-authoritative casino suite, and architected a VR training simulator for airport ground crews.

Capabilities

Agentic AI
Claude Code as a daily primary engineering tool · Multi-model LLM orchestration across Anthropic and OpenAI, routed by task and cost · Model Context Protocol (MCP) server in production against a headless build toolchain · Tool and function calling · Prompt and context pipelines versioned in git, deployed through CI · Per-model token and cost instrumentation metered into billing
Evaluation
Deterministic compile-and-run gate on every generated project, blocking release on failure · Correctness measured rather than reviewed · Automated regression and policy testing in CI
Backend & platform
C# · TypeScript / Node · REST and WebSocket services · Webhook handling with idempotent retries · Microservice and third-party integration · Firebase / Firestore · Cloudflare Workers and R2 · Stripe billing
Generative media
Three years on the ElevenLabs voice APIs across two shipped products · Automated pipelines producing 3D assets, audio, imagery and code from a text description · Import, validation, versioning, packaging, deployment
Game systems
3Cs: character, camera, control · Combat and interaction systems · Inventory, progression, save systems · HUD and UI integration, multiple game modes · 3D math, procedural generation, physics-driven movement · Photon PUN, Realtime and Fusion · Profiling and memory optimisation across mobile, VR and WebGL
Engines
Unity and C# (expert) · Godot (production) · Babylon.js with custom shaders (production) · ShiVa3D (production, 20M+ downloads) · C++ on the Nebula engine · Unreal (working knowledge)
Operations
GitHub Actions CI/CD · Automated regression and policy testing · Structured logging and cost telemetry · Production incident response on a live system
