01About

Engineer first. Lead by listening.

I'm an Android engineer focused on Kotlin Multiplatform, Jetpack Compose, and QA automation for POS systems. Day to day I ship features that handle real financial transactions on Ingenico terminals — the kind of devices you tap your card on at a checkout.

Beyond the code, I coordinate a team, review pull requests, and keep delivery on rhythm. I care about scalable architecture, clean UI, and helping teammates grow.
