Hyud is a productivity app for iOS & macOS that helps you block websites and apps, reduce your screen time, and improve your productivity.

● The Mac app was built withSwift 6**, **SwiftUI& **AppKit**.

● The iOS app was built withTypeScript**, **React Native**, **Expo**, **Swift(for Expo Modules),EffectTS& **TailwindCSS**.

● The backend was built withTypeScript**, **Node.js& **EffectTS**.

For the Mac app, I developed a posture recognition AI model by combining body keypoint detection with MoveNet and a neural network trained under TensorFlow/Keras.

The model learns from annotated images (dataset) to predict several posture-related scores, such as back slouching and head position.

I then exported the model to integrate it into the app and automate posture evaluation from an image.

🎯Mission Objectives

Maintain, improve, and develop new features on the Europcar and Ubeeqo applications.

Within a team of 10 iOS developers, I worked on the Europcar iOS application as well as the Ubeeqo iOS application (Spain & UK).

On Europcar:

→ Development of new features with Swift

→ Creation of the application's new network layer

→ Migration of our dependencies from Cocoapods to SPM

→ Partial migration of the UI from UIKit to SwiftUI

→ Migration of the old API to the new one

→ Resolution of memory leaks

→ Resolution of various bugs and crashes

→ Development of unit tests, snapshot tests, and UI tests

→ Release of the Europcar iOS application

→ Presentations of technical topics to the iOS team

On Ubeeqo:

→ Part of the billing squad

→ Migration of payment APIs, SDK updates, bug resolution

→ Implementation of user tracking

→ Migration from Braze to Salesforce Marketing Cloud

→ Italian migration of the application

→ Release process for ES & UK applications

→ Resolution of various bugs and crashes

→ Resolution of memory leaks

→ Migration of our internal dependencies from Cocoapods to SPM

→ Development of unit tests and snapshot tests

🛠️Technical Stack

→ Swift 5

→ SwiftUI & UIKit

→ Combine

→ Cocoapods & Swift Package Manager

→ Fastlane

→ CI/CD: Bitrise

→ Clean Architecture: MVVM (Europcar) & VIPER (Ubeeqo)

🎯Context

ForJin**, an influence and digital communication agency based in Paris, I worked as a **fullstack developerin a team of 3 developers and a product owner on Jervis (formerly PlugR), a customizable monitoring tool available on mobile and web.

→ Development of the application from scratch inSwift(**MVVM + Combine**)

→ Development of unit tests

→ Deployment withFastlane

The application allowed users to monitor topics of their choice simply. For example, it was possible to monitor a topic and receive results (newspaper articles, tweets, Facebook posts, YouTube videos) on their application via a customizable request.

✅Backend Development

→ Development of new features withTypescript&Node.js

→ Refactoring and bug fixing

→ Writing unit tests withMocha&Chai

→ Implementation ofCI/CD(**Bitbucket Pipeline**) for microservices

→ Management and improvement of themicroservices architectureonAWS(ECS, EC2, ELB, SQS, Route53 etc.)

→ Creation of an orchestration program to improve indexing of results in **ElasticSearch**, reduce infrastructure load, and cut costs

✅Development of new features on the webapp

→ Development of some features withVueJS

→ Bug fixing
