Freelancer profile translated to English.

Description

Certified PSPO I Product Owner and AI for Product Owners, with a dual expertise in product and React.js / React Native development, I help entrepreneurs, startups, and small teams frame, develop, and unlock their web and mobile applications.

My profile is hybrid: I understand product challenges, user experience, business constraints, and technical execution. Before becoming a Product Owner, I worked for several years as a front-end React.js / TypeScript developer on web and application projects for demanding environments: public institutions, media, healthcare, and compliance.

I created and launched VigiApp, a local alert and community mutual aid mobile application for the Brazilian market. On this project, I managed the product vision, roadmap, mobile UX, React Native / Expo development, Firebase, Firestore, Cloud Functions, FCM push notifications, AdMob, RevenueCat, geolocation, Google Play publication, and product iterations.

I intervene on:

Product framing, MVP, roadmap, and prioritization;
User stories, acceptance criteria, and backlog;
React.js / React Native / Expo development;
Firebase Auth, Firestore, Cloud Functions, and FCM;
Push notifications and targeting logic;
Android / Google Play Console publication;

Expo / Android / Firebase debugging;
