Freelancer profile translated to English.

Description

Software engineering graduate with over 10 years of experience in developing web and mobile applications, I have participated in large-scale projects in the banking, insurance, and services sectors. Specializing in JavaScript/TypeScript and expert in modern frameworks (React.js, Angular, Vue.js, Node.js, Nest.js, Next.js), I work on both the frontend and the backend.

Over my experiences, I have acquired solid expertise in:

• Designing and developing complex and high-performance web applications.

• Integrating and consuming REST/GraphQL APIs, implementing BFF (Backend For Frontend).

• Software quality (unit tests, E2E, mutation testing with Jest, Cypress, Playwright, Stryker.js).

• Using headless CMS (Contentful, ContentStack) and optimizing web performance.

• DevOps environments (GitLab CI/CD, Docker, SonarQube, Azure).

Passionate about new technologies, I enjoy tackling technical challenges, sharing my knowledge within teams, and contributing to project success through robust, scalable, and user-oriented solutions.
