Mobile Developer at Deloitte, Milano
I am currently leading the development of a new cross-platform IoT app in Flutter for iOS and Android at Deloitte,
connected to the latest coffee machines of a renowned Italian manufacturer.
As the lead mobile developer, I coordinate an international team of 6 mobile developers,
handling code reviews, architectural decisions, and supporting the team in solving complex issues.
The app communicates with the coffee machines via AWS IoT Core, utilizing
WebSocket for LAN-to-LAN communication and MQTT via the cloud.
To ensure seamless interoperability, we developed two native modules in Kotlin and Swift:
ApplianceKit – for direct communication with the coffee machine
IdentityKit – for user authentication
We integrated these modules into the Flutter app through custom Flutter plugins that we designed and implemented.
Technologies Used
State Management: BLoC
Dependency Injection: GetIt
Networking: Dio, Retrofit
Code Generation: Freezed
Navigation: AutoRoute
Unit Tests: bloc_test, executed in Jenkins CI/CD pipeline
Scalable and Modular Architecture
We designed a scalable and modular architecture, separating business logic from UI using BLoC
and managing dependencies with GetIt. The project follows Clean Architecture principles, with a
well-structured modular approach, dividing the codebase into core and feature layers while adhering to
SOLID principles and design patterns.
Performance Optimization & Security
A strong focus was placed on performance optimization and security, particularly in the LAN-to-LAN WebSocket communication
and MQTT over the cloud. We implemented industry best practices, including Security measures: Certificate pinning, Frida detection, rooting & emulator detection, and other security enhancements
Strategic Contributions & Team Leadership
Beyond development, my role involves:
Technical analysis and effort estimation for new features and projects
Mentoring junior team members, ensuring knowledge sharing and team growth
Code reviews, refactoring, and bug fixing, maintaining high-quality code standards
Daily collaboration with stakeholders, including product owners, testers, designers, backend, and firmware teams, including Deloitte and the client's streams
