Building the tools behind the things you love

Platform engineer and graphics programmer who's shipped tools and systems across DreamWorks, Blizzard, and XBOX - spanning film lighting pipelines, AAA engine graphics, and platform developer tooling. Most at home in rendering, engine, and developer-tools work.

01 - Experience

Experience

From hands-on rendering and pipeline work to platform-level systems design and partner engineering - each role built on the last.

Microsoft - XBOX

Developer Relations
Scope Owning partner technical strategy for the development and live service of major AAA games on XBOX, including multiple shipped titles.
Platform Designing partner platform solutions across the company - Azure, DirectX 12, PlayFab, the GDK, and third-party engines like Unreal Engine 5 - built around each studio's needs.
Hands-on Built the official XBOX GDK + PlayFab port of Godot (C++, DirectX 12, GDScript) plus public samples covering ~85% of the XBOX SDK surface for the community.
Systems Secure production workflow automation and agentic AI systems with C#, TypeScript, Azure, Dynamics, and MS Graph.
Tooling A novel Adversarial Documentation Testing CI/CD workflow for continuous documentation improvement.
Support Debugging partner hardware and software issues with Fiddler, Sentry, and proprietary network tooling.

DreamWorks Animation

Lighting and LookDev Tools
Scope Houdini ecosystem extensions, OpenUSD workflows, surfacing & lighting automation.
Leverage Prior Lighting TD experience to target real friction points in shot iteration and look development.
Stability Built 30+ Python pipeline tools and services with CI/CD across production systems, reducing tool failures and improving artist confidence.
Latency Refactored the USD Asset Resolver into a multithreaded C++/ZeroMQ client-server architecture, cutting path-resolution and scene-composition latency 30%+ studio-wide.
Adoption Drove internal OpenUSD initiatives - pipeline integration, hdMoonray, and systems improvements.

Blizzard Entertainment

World of Warcraft Engine
Focus GPU-driven particle system for World of Warcraft - compute shaders, mesh emission, and VFX tooling.
Constraint Performance targets across a wide hardware range, including legacy GPU support.
Pipeline Built mesh emission features enabling richer VFX artist workflows.
Features Force fields, noise functions, and shape emitters for the compute particle system.
Profiling GPU profiling and frame budget optimization using RenderDoc and internal tools.

Twitch Interactive

Android Mobile Gaming
Goal Build a performant overlay rendering system for the Twitch Android creator tools.
Result Improved stream overlay performance on mobile, directly supporting creator workflows.
Rendering OpenGL ES overlay pipeline optimized for low-end Android devices.
Architecture RxJava reactive data flows with careful lifecycle and memory management.
Quality Comprehensive JUnit and integration test coverage for the rendering layer.
Intel Corporation - Firmware Security

Intel Corporation

Firmware Security
Objective Increase early detection of configuration regressions in simulated SoC.
Method Large-scale simulation of firmware configs on FPGA + automated C/Python harnesses.
Coverage Firmware initialization & microcode interaction pathways.
Automation Bash scripts shortening repetitive validation loops.
University of Kentucky - Computer Vision

University of Kentucky

Computer Vision
Publications 2 peer‑reviewed papers on GPU‑accelerated biomedical imaging; conference presentations.
Enablement Trained researchers on optimized visualization workflows for biomedical datasets.
Acceleration CUDA / shader pipelines reduced imaging preprocessing latency.
Workflow Standardized data prep & visualization scripts adopted across lab.
University of Kentucky - Cloud Infrastructure

University of Kentucky

Cloud Infrastructure
Scope Department software deployment & internal application process automation.
Shift Transitioned from ad‑hoc servers to reproducible containerized delivery.
Automation Streamlined faculty/staff job application processing scripts.
Containerization Re‑packaged legacy services into Docker images for portability.
Portal Maintained faculty data portal (JavaScript / PHP) with iterative enhancements.
