Consumer products fail not because of bad UI, but because designers never deeply understand why people come back — or why they stop.

I invest heavily in understanding the systems, constraints, and mental models of the people I design for before proposing solutions.

UX maturity isn't about having more designers. It's about embedding design thinking into how organizations make decisions.

My most impactful work has been enabling teams without UX support to apply research practices and design frameworks independently.

The best design leadership is invisible. When teams naturally make user-centered decisions without being told to, you've done your job.

I focus on building systems, rituals, and shared language that outlast any individual project.

I build things, not just design them.

A collection of web apps I built from scratch — using AI-assisted coding to turn ideas into working products. This is where design intent meets implementation.

I focus on what requires human judgment — understanding context, navigating ambiguity, and making decisions that serve users and the business. I use AI as a force multiplier to compress the time between hypothesis and validation, so teams can spend more time on the hard decisions.

Product Discovery & Direction

Frame problems, validate ideas through rapid prototyping, and define what to build before production code is written.

Research at Scale

Plan studies, synthesize transcripts and data, and build living insight repositories that teams can explore and grow independently.

Cross-Functional Execution

Move teams from insight to shipped outcomes with clarity and alignment across design, product, and engineering.

UX Vision & Strategy

Define principles, direction, and experience foundations that align teams and guide long-term decisions.

UX Maturity & Enablement

Help teams grow confidence, autonomy, and consistency — through coaching, playbooks, and practices that scale beyond any single project.

Remote-First & Open Source

5+ years in distributed teams across time zones. Experienced designing within open-source ecosystems (Backstage), balancing transparency with product needs.
