About

At the beginning of 2021, I dove into the iOS world through the Apple Developer Academy, following a research scholarship focused on data collection and qualitative analysis. While at Apple, I also helped start an event management startup, making great connections with clients, sponsors, and investors. Now, I share my tech and development knowledge on Instagram.
