Previous work

  • 2020-2021 • Synesis

    Secure Enterprise Messenger

    Designed a secure team messenger across iOS, Android, and Web — workspaces and P2P/group chat. I also built the design system and an in-app feedback loop that helped us spot and fix issues faster.

  • 2019-2020 • Synesis

    Scalable Design System

    Built the core component library and clear guidelines with engineers. Reworked color tokens to an opacity model — fewer blend issues, easy theming, and quicker shipping.

About

I design product experiences for messy, real-world workflows. I’m a problem-first, evidence-driven designer with 9 years of experience. I move fast from lo-fi to testable prototypes, balance flexibility with constraints, and work tightly with PM and Engineering to ship work that serves both the business and the people using it.
