Prototype what you’ll eventually ship
Ideas shouldn’t be judged through static mockups. I build production-quality prototypes in VS Code and Xcode so interactions can be experienced, tested, and refined before engineering begins.

AI products can’t be judged from static mockups. My process blends design, code, and live AI models to prototype, validate, and refine interactions before engineering begins.
Validate with real AI, not placeholders
Every prototype connects to live models through Azure AI Foundry, Microsoft Graph, and production APIs, testing real conversations, voice, retrieval, and multimodal workflows from day one.
Design behavior, not just interfaces
The hardest AI problems happen between prompts and responses. I prototype streaming, memory, interruptions, voice, and multimodal interactions that static screens simply can’t communicate.
Bridge design and engineering
I don’t stop at handoff. I contribute production code, raise pull requests, build internal AI tools, and create workflows that help ideas ship faster while preserving design intent.
