About Elie

By joining your technical team, I design and develop robust and scalable web and mobile solutions, leveraging Node.js, React, NestJS, and TypeScript stacks. I apply rigorous methodologies like TDD (Test-Driven Development), EDD (Event-Driven Development), and Clean Architecture principles to ensure maintainable and high-quality code.

đŸ’» Frontend
Developing modern applications with React (and ecosystems like Next.js, Preact) and Vue.js (Nuxt). Integrating state management solutions (Redux, MobX, Vuex) and mastering the latest CSS features, as well as SASS, SCSS, and LESS preprocessors.

đŸ’» Backend
Designing REST and GraphQL APIs with NestJS or TS.ed, using microservices or monolithic architectures. Integrating messaging systems (RabbitMQ, Kafka) and caching (Redis) to optimize performance.

đŸ’» Mobile
Developing cross-platform applications with React Native and Tauri, deployed via Expo, Firebase, or native stores. Knowledge of Flutter (Dart) for specific projects.

📚 Databases
Designing optimized data schemas for SQL (PostgreSQL, MySQL) and NoSQL (MongoDB, Elasticsearch).

⚒ Testing and CI/CD
Implementing unit, functional, and integration tests (TDD). Configuring CI/CD pipelines with GitLab or GitHub, containerization with Docker, and deployment on Kubernetes or Swarm.

☁ Cloud
Mastery of cloud tools (AWS, GCP, Firebase, Atlas) for scalable and secure deployments.

đŸ‘· Agile Management
Managing projects using Agile methodologies: writing User Stories, organizing sprints, facilitating Poker Plannings, Dailies, and Sprint Reviews.

With an approach focused on quality and scalability, I am committed to delivering technical solutions aligned with your business needs.
