Architect & Tool Builder Who Makes Complex Systems Legible
I build systems that last and tools that explain them. Most engineers choose: go deep technically or go broad into management. I oscillate based on what the problem needs. Most ML engineers throw models over the wall. I build the visualization and tooling stack that brings humans into the loop—so others can understand the problem and see how the solution works.
Mathematical and creative problem solver open to Senior IC or Leadership roles building transformative AI products at startups or big tech.
Every ML system comes with its visualization: I don't just build models—I build the tools that let humans understand what the model sees, debug its failures, and trust its decisions
Systems that outlast their creators: Comment ranking algorithms still running 10+ years later at Meta scale; infrastructure that survives team turnover and strategy pivots
Mathematician who speaks product: Applied math foundations let me jump domains (vision, VR, drones, medical AI) while tooling instincts ensure the work actually ships
Leadership that oscillates: Staff Engineer, Tech Lead, or managing 100+ people across orgs—I go where the problem needs me, not where the ladder points
12 patents, zero orphans: Every invention came with documentation, visualization, and a path to production
Taste meets utility: Hired ex-Pixar talent, curated avant-garde AR effects, built thermal haptic controllers—because delight and function aren't opposites
