The challenge

Separate native applications created duplicated delivery effort while payment, bill, notification, and delivery journeys still needed dependable platform integrations.

My contribution

I was the main contributor to the AtozPay Flutter rewrite, completed its Dart null-safety migration, and delivered PPOB, Finnet transfer, Firebase, deep-link, and merchant order workflows.

The outcome

Shared Flutter foundations reduced duplicated platform work while preserving native-level capabilities across payment and delivery experiences.

How I approached it

I worked across native Android and Flutter, using the migration to consolidate common behavior without ignoring platform-specific needs. The transaction work included train booking, electricity and TV bill inquiries, top-ups, and Finnet balance transfers.
