VASCO BARREIROS

As a Lead Front-End Developer on the BOGS project, I played a key role in the development of the mobile app, the back office system, and the showcase website, utilizing my expertise to create seamless, high-performance user interfaces.

For the BOGS mobile app, developed in React Native with TypeScript, I built and optimized over 60 interactive screens. I focused on delivering a responsive and fluid user experience, ensuring smooth transitions and real-time updates using Zustand for state management and TanStack Query for efficient API data fetching, caching, and synchronization. I also integrated Stripe for secure in-app payments and Firebase for push notifications, enabling real-time engagement with users.

In the development of the back office, I worked closely with the admin team to create a powerful and intuitive management dashboard using React and TypeScript. This interface allows administrators to monitor user activities, track transactions, and analyze performance statistics in real time. I ensured smooth data flows between the back office and the database via NestJS APIs, managing user data, match histories, and financial transactions. With MongoDB and Redis used for caching and session management, I optimized performance, ensuring fast, secure access to critical data.

For the BOGS showcase website, I designed and developed a visually appealing and responsive marketing platform using HTML, SCSS, JavaScript, and TypeScript. The site showcases the app’s features, encouraging user engagement and driving downloads, with a strong emphasis on loading speed, cross-browser compatibility, and SEO optimization.

Across all projects, I leveraged modern front-end technologies to deliver scalable, performant solutions, ensuring smooth interactions between the UI and backend APIs while maintaining a user-centric focus. My work has been instrumental in creating a robust, engaging ecosystem for the BOGS community.

As the Front-End Developer for the Proxity platform, I designed and developed a Progressive Web App (PWA) that allows local merchants to manage their customers and loyalty programs efficiently. The app was built using Vue.js, TypeScript, and SCSS to ensure a smooth, responsive user experience across all devices.

One of my key contributions was migrating the PWA from Vue 2 to Vue 3, which greatly improved performance, modularity, and scalability. This migration allowed the app to take advantage of Vue 3’s Composition API, providing better component organization and maintenance.

I also developed a comprehensive statistics dashboard where merchants can track key metrics such as customer sign-ups, purchase history, and cashback balances. The app features client management tools that allow merchants to create and update customer profiles, as well as scan and issue digital loyalty cards, making the user experience seamless.

Additionally, I created a back office for Proxity’s internal team using Vue.js and TypeScript, enabling administrators to monitor merchant activities, process transactions, and analyze platform performance. I handled API integration with NestJS for real-time data synchronization, ensuring a smooth flow of data between the back office and the PWA.

Through the use of modern front-end technologies and best practices, I delivered a robust, scalable platform that supports Proxity’s mission of fostering customer loyalty and driving business growth for local merchants.
