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. And now I'm sharing content with over 22K+!

Work Experience

TELUS Digital & WillowTree

Jan 2024 - Present
iOS Engineer
At TELUS Digital (formerly WillowTree), I work as an iOS Engineer on large-scale consumer applications, contributing to products used by millions of users daily. I currently help drive development on one of the most downloaded mobile apps in New York, owning the end-to-end Search redesign and Analytics implementation as the directly responsible individual (DRI) from the engineering team. Alongside this, I’m part of the core redesign team, leading major screen updates and building new features from concept to production across the application. Previously, I worked on a large-scale insurance application and contributed directly to a high-traffic consumer mobile app with over 90 million downloads and more than 23 million monthly active users across the United States. I was a core contributor to a shared SDK and product UI system, building reusable components adopted across the app, helping design internal APIs, leading technical discussions, and driving accessibility improvements that later influenced native platform components. My work emphasizes clean architecture, scalable UI systems, and thoughtful user experiences for high-traffic products, helping improve stability, usability, and overall customer satisfaction.

WillowTree

Jan 2023 - Jan 2024
iOS Engineer
As an iOS Developer Intern at WillowTree/Poatek, I worked on the company's internal mobile application, owning significant parts of its architecture and implementation. I built production features using UIKit and SwiftUI, applied modular design, accessibility best practices, and clean code principles, and helped introduce architectural patterns such as Coordinators and Clean Architecture. During this time, I also contributed to a large-scale insurance application, gaining early experience working on enterprise-grade products. I further developed hands-on experience with CI/CD pipelines, unit and snapshot testing, and SOLID principles to improve maintainability and scalability. This role gave me early exposure to building real-world products in a collaborative engineering environment and laid the foundation for my approach to delivering high-quality, user-focused applications.

DaVInt Lab

Jan 2020 - Jan 2021
Software Engineering Scholarship
At DaVInt, I developed a data automation algorithm to collect climate change-related news articles from major Brazilian media outlets over the past 10 years. The solution automated large-scale data extraction and processing, reducing manual work by over 90% and enabling advanced analysis using n-grams and sentiment analysis. This supported research on the social perception and media coverage of climate change impacts in Brazil over time.
