Principal Architect with deep expertise in computational geometry, local-first software architecture, and AI-accelerated development. I bridge the gap between complex engineering design problems and realizing high-performance user interfaces.
Currently at Flexcompute, I am helping to define the next generation of GPU-based physics simulation software. Leveraging local-first principles (CRDTs), AI-accelerated development, and high-performance visualization (WebGPU/WebGL), I build reactive environments that democratize access to simulation and tighten the feedback loop for rapid design iteration.
April 2024 – Present
- Local-First Architecture (Photonforge): Led frontend development for Photonforge, a next-generation photonics simulation platform. Architected the application on a novel local-first foundation using Automerge CRDTs, IndexedDB/OPFS, and a Common Schema (Zod/Pydantic). This architecture eliminated backend boilerplate, simplified state management, and ensured end-to-end type safety.
- High-Performance Visualization (Flow360): Led the development of the 3D visualization framework used in Flow360, a Computational Fluid Dynamics (CFD) solver. Optimized large-scale rendering of CAD models and simulation results in the browser, adopting ES signals for a reactive, high-frequency user interface.
- AI-Accelerated Workflow: Pioneered an AI-integrated development process using Story Design Journals (SDJ). Defined technical standards that allow AI agents to synthesize requirements and generate working prototypes, dramatically accelerating the concept-to-production lifecycle.
- Standardization & Leadership: Initiated a Common Schema strategy to enforce strict data contracts across multiple languages; currently driving company-wide adoption. Successfully transitioned the established 3D framework to focus on greenfield architecture.
- Modern Component Design: Standardized frontend development on React Aria and Panda CSS with design tokens synced to Figma, creating reliable, AI-friendly component factories.
December 2021 – April 2024
- Player-Coach of the engineering team responsible for extracting & analyzing technical data from 2D/3D CAD models to drive the platform's pricing engine.
- Lead developer for the 3D part viewer. Reduced CAD model load times by >200% via dynamic chunking (40-50ms blocks) and asynchronous streaming, preventing UI lock-up.
- Increased rendering performance by 30X by optimizing WebGL buffer packing to reduce draw calls, while enabling the manipulation of complex assemblies directly in the browser.
- Leveraged IndexedDB to cache geometric data, significantly reducing network traffic and AWS costs.
May 2016 — November 2021
- Led front-end development for a cloud-native stormwater management platform that monitors and controls watershed infrastructure, enabling communities to improve water quality, prevent flooding, and reduce combined sewer overflows.
- Built reactive services using async iterators to visualize real-time weather and sensor data, connecting civil infrastructure to cloud-based control systems.
- Built end-to-end distributed tracing (Logz.io) to track async user flows and reduce support time.
2000 - 2016
July 2012 - February 2016
- Conceived, pitched, and managed "Expert Model Analysis" (XMA), a product that scans gigabytes of Creo and Pro/ENGINEER data to identify modeling quality issues.
- Oversaw a 12-person global team (Dev, UX, QA). In its first year, XMA generated $560K in license revenue and influenced $1M+ in consulting sales.
- Learning Initiatives Technical Lead: Led development of the "Best Practice Academy", a new training methodology for experienced engineers focusing on heuristic application over feature function.
- Master Process Architect: Consulted for major clients (Synthes, GE Healthcare, Raytheon) on PLM, requirements management, and manufacturing process planning.
- Development Manager: Principal developer of PTC’s consulting portfolio. Created XML authoring strategies still in use today to support a $200M+ services business.
- Technical Support: Specialized in complex surface geometry, 5-axis CNC programming, and mold design.
July 1999 — April 2000
- Invented a revolutionary fan blade for high-flow suction applications. (United States Patent 6,280,143)
