Open to new opportunities

Hi, I'm Katherine,
turning fuzzy ideas into thoughtful AI products.

I'm an AI product builder focused on agentic systems, human-AI interaction, and evaluation-driven product design. With a background in software development, psychology, and learning science, I build tools that help people think, decide, learn, and act with more clarity.

Happy to chat about AI products, agentic systems, or whatever you're building.

A little about me

I like working on messy, human problems and turning them into tools people can actually use. My path has moved through software development, psychology, learning science, and human-AI interaction. Along the way, I've built multi-agent decision tools, learning products, and interactive AI systems across research, startup, and academic settings. What I care about most is making complex ideas feel clearer, more useful, and easier to act on.

01
Product
From problem framing to MVP: roadmaps, specs, and the tough trade-offs that protect delivery timelines.
02
Research
Psychology-informed user insight. Mixed-methods research that turns messy human needs into actionable findings.
03
Technical
Hands-on with LLM evaluation, agent orchestration, and prompt architecture. I can read the traces, not just the outputs.
