2020 – 2022

Studio Manager

  • Took the studio from losing money to profitable by restructuring how projects were staffed and outsourced.
  • Managed studio projects end to end, from understanding client needs to making sure the final product delivered on them.

UX Designer

2018 – 2020

  • Designed across B2B, B2C, e-commerce, mobile, and complex internal tools, always starting from why users behave the way they do, not just what they say they want.
  • Ran client interviews and user research to build real user profiles, user flows, and journeys grounded in behavior, not assumptions.
  • Turned research into wireframes and prototypes, running usability testing to validate ideas cheaply before investing in final designs.

Behavioral Therapist Self-Employed

CBT links thoughts, feelings, and behavior to shift distorted thinking.

2017 – 2018

CBT Therapist

  • Practiced CBT with individual clients dealing with anxiety and depression, working directly with what drives decisions and resistance to change.
  • This is where I trained the skill that now defines how I design: reading what people actually need, even when it's not what they say out loud.
