Jason Maskell

— Sole architect/author of the company's TypeScript narrative engine: ported the legacy C# engine to parity (file-by-file parity tests; Stryker mutation testing with 90%+ thresholds) and replaced it as the unified multi title backend.

— Zod-first contract architecture: schemas as single source of truth for types and runtime validation at every boundary — no codegen, no drift.

— Built the surrounding platform solo: Go gRPC multi-provider LLM proxy, Go WebSocket STT proxy, AI image generation service (ONNX face detection → vision-model analysis → generation), deploy control plane with atomic symlink-swap content releases, in-game radio broadcast backend, and the CI-integrated LLM evaluation harness with bot playtesting and multi-dimension LLM-judge scoring.

— Designed LLM-runtime game systems: staged generation pipelines with Anthropic prompt caching and safe parallelism (measured 40%+ latency reductions), psychology-driven NPC systems, streaming tool-argument narration.

— Gameplay systems on The Witcher 4 (Unreal Engine 5).

— Prototyped internal AI systems and tools with Claude Code.

— Left to focus full-time on generative AI work.

— Built backend systems for Silent Games' Empyreal (Java/Node.js; Docker, MySQL, Couchbase); refactored the Unreal-side C++ layer.

— Architected and delivered Fracasse.ai (later Chandler) — AI transcription and authoring: audio → edited book (React/TypeScript, Koa, FFmpeg, Deepgram, Claude).

— Led development of Visionary, an AI-driven game-creation platform on AWS: interview → design document → technical decomposition → agent implementation in isolated worktrees. Used it to ship asteroids.fracasse.ai,

a faithful Three.js recreation of 1979's Asteroids, from a Visionary-generated PRD.

— Established CI/CD, monitoring, and development workflows; managed cross-functional frontend/backend/AI teams.
