I closely collaborated with Android and back-end engineers to define client responses. Part of my responsibility was to work on the back-end to serve the required data to the iOS and Android clients. I was also responsible for developing new features and fixing bugs on iOS while maintaining and writing clean, concise, and testable code. I participated in all stages of feature development, from brainstorming, architectural designing, and tech decision-making to release and monitoring to ensure stability. Additionally, I worked closely with the data science team to define experiments and measure success. Furthermore, I collaborated with the design team to iterate and define UI/UX.

I collaborated closely with back-end engineers to define the endpoints that served data through a REST client to the iOS app. I also worked with other iOS engineers to establish best practices. In addition, I worked closely with project managers and designers to determine feature requirements and minimum viable product (MVP) criteria. I utilized test-driven development for new feature development and bug fixing. Finally, I worked in a fast-paced environment while maintaining stability using feature flags.

I developed new expense report SDK features while maintaining maintainability and scalability. To do this, I used the ReSwift framework and followed the TDD approach for new features and bug fixes. I also simplified dark mode support by centralizing shared code in one static library. Additionally, I worked on upgrading our app to iOS 14 and created and maintained comprehensive documentation (WIKIs) to help other teams understand features and migration work. Lastly, I fixed and implemented iOS platform libraries to provide feature engineers with stable and easy-to-use APIs.

I collaborated with my cross-functional team to create new features and functionalities. I regularly met with project managers and other teams to discuss ongoing projects and future development plans. As part of my efforts to improve communication within the team, I introduced a "Coffee stand-up" initiative. This allowed iOS engineers to come together at 3 pm, enjoy a cup of coffee, discuss issues related to their work, or chat. I worked closely with the project managers and my team to ensure we met project timelines, addressed problems, and considered potential trade-offs. To maintain high code development standards, I helped standardize best practices based on Swift and iOS standards, taking into account feedback from the team. In implementing new features and bug fixes, I followed a TDD approach and used VIPER architecture to write code that was both scalable and maintainable.

Boston, Ma, Us

I participated in modularizing the app's features into small static libraries. Using the Test-Driven Development (TDD) approach, I implemented new features and fixed bugs while adhering to VIPER architecture and writing scalable and maintainable code. Additionally, I performed code reviews on pull requests (PR) to ensure that our coding best practices were enforced.

I actively participate in the development of software applications following industry best practices. I was responsible for writing effective unit tests, maintaining and enhancing existing applications, as well as diagnosing and resolving applications bugs. Moreover, I meticulously monitor applications for abnormalities by leveraging crash report services, and proactively seek opportunities to improve application availability and speed. I was also involved in conducting code reviews, providing feedback, and suggesting changes as needed. Lastly, I maintained private Cocoapods libraries in order to ensure the efficiency and security of our software development initiatives.

San Juan, Pr, Us

I developed and integrated advanced technology into native applications for iOS, Android, and web platforms. I also designed user experiences for mobile and web platforms, optimized applications, and performed functional and regression tests. I collaborated with developer teams and scrum masters to maintain project schedules and tasks. I maintained effective communication using Agile methodology in daily stand-ups and avoided Massive View Controllers (MVC) while developing iOS native applications using unit testing best practices and TDD.

I am an experienced iOS developer with proficient skills in designing and creating native applications. I can identify and resolve bugs efficiently and optimize mobile applications. I also possess strong collaboration and time-management skills to ensure timely project completion.
