Project Overview

Three mobile apps lived because three teams did: Rx, Patient, and Guide. Each had a surface to protect. The member started over each time they switched. That looks like ownership on a dashboard and like a dongle in the person's hand.

I led the merge onto one React Native platform for 13M members. One session, one job, one place the member finished. We also shipped GenAI workflows, a personalized home screen, and a chat interface on Epic APIs. Advising the mobile center of excellence on experimentation, accessibility, and AI adoption was a side duty, not the job.

Key Challenges

  • Three apps meant three starts for a refill, a find-care job, or a message to a clinician.
  • Feature work shipped twice, and the run-rate stayed high because two codebases stayed alive.
  • Teams scored on their own surface had no reason to kill it.
  • Call-center load stayed high because the app could not finish the job.

Solution & Approach

One platform

Merged Rx, Patient, and Guide onto React Native. One release pipeline. One session. A member could finish a job without starting over in a second app.

GenAI where it earned a place

Personalized home screen and a chat interface on Epic APIs and LLMs. The point was engagement and taking load off the call center, not a demo.

CoE as a side duty

Advised the mobile center of excellence on experimentation, accessibility, and AI adoption. That is not the Optum story. The merge is.

Results & Impact

  • 13M members on one app

    Rx, Patient, and Guide became one session so a member could finish a job without starting over.

  • Roughly $5M a year off the run-rate

    Two extra codebases stopped being a tax on every feature.

  • Feature delivery sped up 40%

    Built once, shipped once, on one React Native platform.

  • Call-center load came off the app

    GenAI workflows and chat on Epic APIs so members could finish more jobs in the product.
