Dear hiring team,

I understand that the central requirement for this Product Designer role is connecting user research, interaction decisions, prototypes, accessibility, and product constraints into shipped experiences. I want to design products where evidence and craft work together to make difficult tasks feel understandable and trustworthy.

I completed this work during a supervised Product Designer Intern placement. Under supervision, I carried a complex form from sketches through an interactive prototype, tested error recovery with users, and documented component states for engineering handoff.

Within that same supervised placement, I limit my claim to the assigned work. Under supervision, I released an accessibility handoff for the Adobe asset-management workflow, using keyboard tests to resolve hidden focus, ambiguous selection and unreadable error states.

I would welcome the opportunity to discuss the decisions and delivery I owned, and how I could apply that experience in this role.

Sincerely,

J. Lee

What a Product Designer application needs to prove

connecting user research, interaction decisions, prototypes, accessibility, and product constraints into shipped experiences

Work the resume should make concrete

  • observed 16 small-business owners completing payout setup and mapped 7 failure points
  • prototyped and tested three identity-verification flows with 18 participants
  • defined interaction and content patterns for 26 form components
  • audited keyboard, focus, and error behavior across 12 priority journeys

Evidence a reviewer should be able to find

  • End-to-end ownership — User problem and research choice
  • Decision and trade-off — Constraint and interaction decision
  • Cross-functional delivery — Shipped scope
  • Outcome verification — User and business outcome
