WHAT I DO
I work at the intersection of product definition, interaction design, and execution systems.
My strength is taking problems that are still undefined, strategically sensitive, or technically constrained, and turning them into products teams can actually build and scale. Sometimes that means leading. Sometimes that means designing the first version myself and stepping away once the direction is clear.

THE CRAFT
Code as a design tool — before AI, and even more with it.
I've always used code as a design tool — building shared systems, prototyping interactions too complex for Figma, and closing the gap between intent and implementation. AI coding agents turned that into a superpower. With a structured control system I designed for autonomous agent work, I now fully leverage my cross-disciplinary fluency in design, product, and engineering at a pace that wasn't possible before.
Interaction
Primitives, micro-interactions, and system-level patterns that scale across products.
Engineering
Shipping design decisions directly in production codebases.
Product
Scoping, sequencing, and making tradeoffs before pixels.
EXPERIENCE SNAPSHOT

HOW I WORK
Tight discovery loops, clear intent, and execution that doesn't depend on me.
Deliberate thinking, fast execution
Investing heavily upfront to clarify constraints, tradeoffs, and intent, so execution moves quickly without rework.
Systems over screens
Interaction models, primitives, and patterns that hold together across teams and iterations.
Product ownership mindset
Designing with unit economics, engineering cost, and long-term maintainability in mind.
Building teams that don't need me
Small teams designed to operate without constant oversight. Removing ambiguity early and becoming unnecessary over time.
BEYOND THE ROLE
Sustainable pace, continuous learning, and systems thinking beyond work.
I value sustainable performance and depth over constant acceleration.
Outside of work, I'm a parent of two and spend my time learning how complex systems behave, from interaction design to human psychology. I wrote about that balance:
