Andri Fritzent

Revamped Dipay Business with an updated tech stack, migrating state management from GetX to BLoC and reducing app size (including converting image assets to WebP). Implemented multi-environment builds for development and production with separate Firebase projects. Set up Fastlane for Android and iOS to automate builds and distribute to Firebase App Distribution. Built and maintained Dipay Personal and Dipay Business end to end, including third-party payment SDK integrations, bug fixing, and performance optimization. Integrated Verihub liveness detection to simplify registration and allow users to unlock dormant accounts. Collaborated with PMs and designers to refine requirements and validate UX flows from BRDs, and owned release/testing/publishing to Google Play and App Store Connect.

Transitioned from Xamarin to Flutter through structured learning and multiple independent projects. Built apps using BLoC/Cubit and GetX, clean architecture patterns, Firebase (Firestore/Auth/Storage), REST APIs via Dio/Http, and local storage with Hive and Flutter Secure Storage. Practiced real-world features such as offline-first storage, OTP authentication, geolocation, and reusable custom widgets.

Developed and maintained Android apps in Xamarin for iSeller modules (F&B, Retail, Express, Admin, and SSK) and for Livin’ Merchant by Mandiri. Worked closely with UI/UX designers to deliver clean, intuitive interfaces. Integrated third-party services including payment gateways and a payment SDK (Dongle). Triaged and fixed reported issues, and mentored new developers on development lifecycle and code review processes.
