Employer Mobile App / EMA
A product intelligence case about synthesizing app feedback, churn, accessibility, rollout, interview workflows, design-system constraints, and AI/Scout opportunities to inform clearer roadmap discussion.
Signals → synthesis → priorities → decision support02
Virtual Recruiter / D.I.F.M.
A high-ambiguity recruiting concept shaped into a clearer product/service direction by making explainable delegation, trust boundaries, explanation moments, and MVP decisions visible.
Employer effort → trust contract → delegated product system03
The Flash Funnel
A mobile-first job-posting case about reducing decision load: auditing an 11-page, 59-click legacy funnel, sorting each input by responsibility, and protecting employer momentum without making the posting feel careless.
Decision load → responsibility sorting → mobile momentum → behavior signals
