Work Experience

Senior iOS Developer

2019 - 2020
  • Implemented ARKit and RealityKit combined with camera tracking, real-world tracking, and image scanning to detect images created by other users. By doing so, I could place a 3D model or a video on a real-world surface.
  • Re-developed the app and separated colossal classes into smaller components that could be closed for change but open for extension. I designed the architecture using a whole system perspective.
  • Re-organized the launch process so I could finish with the last details and bugs on the latest release while others could still work on the features for the following releases. Our production rate increased to uploading a new version every week.

2016 - 2017
Banco Hipotecario
  • Redeveloped the bank's entire iOS app, deleting all old files and owning a complete overhaul of the codebase.
  • Managed the deployment cycle of every version and implemented a Git-based workflow.
  • Implemented 3D Touch and other new features that Apple had recently launched.
  • Created unit tests for every class, which was non-existent before, as well as UI integration tests.
Technologies: Objective-C, iOS

iOS Developer

2015 - 2016
  • Created the company's entire iPad application from scratch.
