Work Experience
iOS and AI Developer
UC Davis, Department of Land, Air and Water Resources - Main
- Developed a machine learning model and applied it to an iOS app to detect tree shades in large crop images. After that, I applied linear regressions to predict the expected yield of the crops for the farmers and industries involved.
- Used Trello for task management and GitHub with integrated CI/CD for pipelining deliverables and code management.
- Developed the machine learning model and trained it with the dataset given. This process gave me an accuracy of +97% when detecting tree shades.
Swift and Firebase Developer
Colby Merkt
- Developed an app that automatically organizes all the apps in folders on the iOS device.
- Used Trello and GitHub for organizing tasks and deliverables and used CI/CD to create a deploy pipeline.
- Oversaw the whole process from the start till the launch of the app.
Senior iOS Developer
Vidit
- 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.
iOS Developer
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.
iOS Developer
Geopagos
- Created the company's entire iPad application from scratch.
- Developed the API interface.
- Improved the version control by expanding it from only one branch to one branch per feature.
