Jason Csizmadi

Designer who builds.
Los Altos, CA jcsizmadi@gmail.com dangergraphics.com github.com/thecsiz linkedin

I build visual languages and design systems at Credit Karma, Patreon, Zillow, Fitbit, and Cooper. I obsess over the details most people ship past: the optical alignment, the easing curve, the half‑pixel. Lately I design agentic AI experiences, build and ship native Mac apps on my own, and teach designers to build with AI. Taste is a skill.

01

Receipts, not promises.

In flight PlainType (private clipboard cleaner) · Argos (native reference library) · Vox (on-device dictation, whisper.cpp) · SpriteForge (node-based VFX engine) · Frontrow (menu-bar meeting alerts). All SwiftUI or native macOS.

Credit Karma

Senior Staff Product Designer
  • Co-lead visual evolution and design system modernization for a financial product serving tens of millions of people.
  • Built a live, LLM-powered product vision prototype in one week, turning a long-range roadmap into working software senior leaders could hold. The conversation moved from slides to decisions.
  • Authored Principles for Designing Agentic AI Experiences, fifteen principles distilled from eighteen months of hands-on agentic design work.
  • Taught AI prototyping to more than 100 product managers and designers through the weekly AI and prototyping guild, making working software the default way to decide. Click-throughs don't count.
  • Hackathon runner-up, 2026, with an AI design critique tool that took the event's top AI score.

Patreon

Product Designer
Three roles in one tenure: visual design, then design systems, then UX lead.
  • Helped define Patreon's 2023 rebrand into a more expressive, accessible, emotionally resonant visual language. The rebrand won the Branding category at Fast Company's Innovation by Design Awards, 2024.
  • Translated that direction into tokenized, cross-platform components used across web and native, for a platform serving 250,000+ creators who have earned over $3.5 billion.
  • Launched built-in livestreaming to creators in 2025. Owned UX strategy and mobile UI: scheduled streams, live chat and moderation, access controls, recordings, and the transitions between community and content.
