04HOW I THINK

The app is only
half the job.

I care about what happens after launch: the crash that never happens, the flow that just makes sense, the team that can ship with confidence.

A little more about me

Mobile depth. Product perspective.

Android and Kotlin for platform integrations. Flutter for shared product architecture. Next.js and backend experience to connect the whole journey.

CROSS-PLATFORM · NATIVE · FULL STACK

Measure. Understand. Improve.

Crash reports, onboarding funnels, and meaningful tests turn assumptions into decisions. Reliability is a product feature.

OBSERVABILITY · PERFORMANCE · TESTING

Own the work. Grow the team.

From architecture to store releases, I stay accountable. At iMumz, that also means leading four engineers and mentoring the next owners.
