- Optimize applications for performance and cost-efficiency within the AWS environment.

- Design and implement efficient data models for both NoSQL (DynamoDB) and relational (PostgreSQL) databases.

- Write optimized database queries and manage database interactions within the backend applications.

- Design, develop, and document RESTful APIs following best practices.

- Contribute to the development and deployment of microservices-based architectures.

- Ensure API security, versioning, and proper error handling.

- Utilize TypeScript extensively for building strongly-typed and maintainable backend applications.

- Apply your knowledge of JavaScript (ES6+) when necessary.

- Utilize Git for version control, code collaboration, and managing code repositories effectively.

- Follow established Git workflows and participate in code reviews.

- Write unit, integration, and potentially end-to-end tests to ensure the quality and stability of the backend applications.

- Participate in code reviews to maintain code quality and share knowledge within the team.

- Collaborate with QA engineers to identify and resolve bugs.

- Demonstrate strong analytical and problem-solving skills to diagnose and resolve complex technical issues across the backend infrastructure and applications.

- Utilize logging and monitoring tools to identify and address potential problems proactively.

- Work closely with frontend developers, mobile developers, product managers, and other stakeholders in an Agile environment.

- Participate in the deployment process of Node.js/NestJS applications to the AWS cloud.

- Provide ongoing support and maintenance for deployed applications.

- Stay up-to-date with the latest advancements in Node.js, NestJS, AWS services, and backend development best practices.

- Proactively learn and adopt new technologies and tools as appropriate.

Requirements :

- 3+ years of proven experience as a Node.js Developer with a strong focus on backend development.

- Proficient in using the NestJS framework (TypeScript) for building scalable server-side applications.

- Strong experience and proficiency in both TypeScript and JavaScript (ES6+).

- Solid understanding and hands-on experience with various AWS services relevant to backend development (e.g., EC2, Lambda, S3, API Gateway, IAM, CloudWatch).

- Expertise in working with DynamoDB, including data modeling and query optimization.

- Expertise in working with PostgreSQL, including schema design and query optimization.

- Knowledge of modern web technologies, backend frameworks, and best practices.

- Experience designing and developing RESTful APIs and familiarity with microservices architectures.

- Proficient in using Git for version control.

- Strong problem-solving skills and the ability to troubleshoot complex issues.

Preferred Qualifications :

- Experience with serverless architectures (AWS Lambda).

- Familiarity with containerization technologies (Docker, Kubernetes).

- Experience with CI/CD pipelines (e.g., AWS CodePipeline, Jenkins, GitLab CI).

- Knowledge of GraphQL.

- Experience with caching mechanisms (e.g., Redis, Memcached).

- Understanding of security best practices for backend development and cloud environments.

- Experience with monitoring and logging tools (e.g., CloudWatch Logs, Datadog, New Relic).

- Familiarity with Agile development methodologies.
