(previously was made by an outsourced company).- Savacash User: https://play.google.com/store/apps/details?id=com.savecash.user ~20k downloads (Android and iOS). The user app is responsible to provide financial informations, show nearby businesses, get discount coupons, manage payment and managing friend referrals. Initially developed in Ionic, one of my first suggestions was recreated in Flutter to create a most scalable app with a good ui/ ux. The change in technology has brought the following benefits: > ~2.5x app startup time. > CI/CD for mobile. > Fresh technology brought ease in implementations (maps, animations).- Savecash Operator: https://play.google.com/store/apps/details?id=com.savecash.operator ~2k downloads (Android, iOS and PWA) The operator app is used to local establishments to make sells for users. Initially the project was made with Ionic/Angular, and provided for desktop OS (mac, windows, linux) with Electron. I carried out the application restructuring implementing the PWA which took only 2 weeks. Due to the use of PWA I helped reduce development/deployment time by at least 60%. In addition to keeping the app for android and ios.- Portals Plataforms: https://meunegocio.savecash.com.br/ +100 Business. Internally 3 web portals (Admin, Partners and establishment) where developed by outsourcing company but were with a bad ui / ux, non-responsive and with several usability problems.
