Nathan ComesAI & Pipeline Engineer
I build production software other people depend on: agentic AI systems, automation pipelines and internal tools in Python, plus AI-assisted C++, with automated tests behind them. Sixteen years of shipping it, including Destiny 2 at Bungie and Xbox at Microsoft.
What I build
Agentic AI
Multi-agent orchestration, tool calling, RAG and memory, cost-aware model routing, sandboxed code execution and MCP integrations.
Pipelines & automation
Production pipelines that whole teams run on every day: launchers, asset registries, batch processing, dependency management.
Testing & reliability
2,947 automated checks across 44 suites. Legacy code modernized without stopping the team that depends on it.
AI-assisted C++
Native plug-ins for numerical problems: interpolation, least squares, physics. I design the approach, direct the implementation with AI, and verify every result with tests. Eigen, OpenMP, multi-version CMake builds.
Selected work
10+ AI systems for a game team
Built with Claude: AI-driven NPCs, an AI-managed item catalog, and automated Unreal setup.
MCA-DCC-Pipeline
A working studio pipeline, made provable: 2,947 checks across four Maya versions.
mcaPoseSkinner
Turns a 173-blendshape face into joints and skin weights a game engine can use.
Animation Library
A studio's animation lived in 1,121 scenes. Now it's a grid you browse and double-click.
How my experience translates
My background is games. The work is the same work most engineering teams do.
| What I did | What it means for your team |
|---|---|
| Studio-wide tools and pipeline at Bungie | Automation and pipelines other teams depend on daily |
| Tools for artists and animators | Internal developer and business tools, with real users and support |
| Python 3.7–3.11 across four Maya versions | Large legacy codebase kept working across a version matrix |
| 2,947 automated checks | Test-driven delivery and regression safety |
| Managed outsourcing studios | Vendor management and cross-team coordination |
| Shipped Destiny 2 and its expansions | Releases on fixed dates at scale, with no room to break things |
Shipped products
Bungie, Microsoft, Signal Studios and Counterplay Games. Armatus, from my time at Counterplay, launches in 2027.
