🚘 Fullstack Developer – Redesign of a fleet management ERP

Client: OKmobility (Fleet Management ERP)

• Complete redesign of an obsolete ERP in an unclear technical context, without formal specifications.

• Creation of reusable components in Angular: complex forms, shared services, dynamic validations.

• Refactoring and centralization of code in an internal library for the entire team.

• Backend with Spring WebFlux (reactive programming): REST APIs, autonomous learning.

• Front (Jest) and back (JUnit) testing, Agile Scrum methodology, rituals entirely in Spanish.

• High autonomy, technical support to the team, and transmission of best practices.

🛠 Web Developer – Legacy application maintenance

Client: Volkswagen Group Spain (OVGED)

• Maintenance of an unstable Angular application, without documentation or technical support.

• Bug fixing on a fragile codebase, with no possibility of refactoring.

• Detailed analysis before each change to avoid regressions.

• Rapid adaptation in an unstructured and very limited environment.

Training and personal projects for technical growth.

• Development of an intelligent iOS keyboard (Swift / SwiftUI / UIKit + local AI).

• Continuous training in modern iOS development (MVVM architecture, Xcode).

• Intensive Catalan courses (CPNL), preparation for the Barcelona half-marathon and marathon.

• Creation of complex forms, state management with Observables, memory optimization (takeUntil, unsubscribe), strict integration of the French State's design system.

• Centralized error management via HTTP Interceptors.

🛠️ Fullstack:

• End-to-end feature management, from API contract modification to frontend implementation, in collaboration with functional teams.

⚙️ Methodology & Tools:
