Technical Leadership: Led major refactoring initiatives on core features, ensuring the performance and maintainability of a rapidly expanding codebase.

Mentoring & Structuring: In a context of sustained recruitment (tech team grew from 5 to 30 members), I handled the onboarding and mentoring of interns and new developers, laying the foundation for the engineering culture.

Technical Environment:

Frontend: React.js, React Native (Mobile), Redux (State management).

UI/UX: Material UI, Storybook (Design System), Figma.

Quality & Tests: Cypress (E2E), Jest (Unit).
