Description

Software engineer specialized in React and TypeScript, with over 4 years of experience in building scalable and maintainable front-end applications.

At Jint (formerly Mozzaik365), I contributed to the evolution of a Design System (Storybook, Jest), developed custom components within the Microsoft 365 ecosystem (SharePoint Framework – SPFx), improved Pull Request workflows, and participated in defining front-end best practices. I also worked extensively on performance optimization, CI/CD pipelines (Azure DevOps), and REST API integration (ASP.NET Core, Node.js).

Previously, as a Front-End Developer at Greenflex, I developed essential React features for the business, optimized application performance, and contributed to the company's Design System evolution.

My experience began with Back-End development at Cegos, where I designed PHP (Laravel) services and WordPress plugins.
