Node.js modernization and Ionic mobile app

Recovery and evolution of a Node.js application unused for more than 4 years, strengthened with TypeScript, testing, and a scalable cloud-oriented approach.

2021 - 2025Role: Responsible for technical modernization, cloud optimization, testing strategy, and mobile app supervision.

Challenge

Bring an abandoned system back to life, reduce technical risk, and prepare its AWS infrastructure to scale with the lowest viable cost.

Solution

Project upgrade, strong typing with TypeScript, optimization for scalable deployment, unit tests, load tests, and AWS cost-saving analysis.

Technical decisions

Added TypeScript to strongly type the code and reduce risk while evolving an old codebase.
Unit and load tests to review functional behavior and response under demand.
AWS infrastructure assessment aimed at scalability with the lowest viable cost.

Impact

More maintainable technical base, validated by tests and aligned with cost-efficient infrastructure; supervision of an Ionic Angular app deployed to Android and iOS.

Results

Application recovered after years without use and prepared for maintainable evolution.
Infrastructure direction aligned with scalable and cost-efficient operation.
Ionic Angular app supervised and deployed to Android and iOS.
