10. AWS stack. Please describe in detail your relevant experience with the AWS stack (S3, EC2, SQS, ELB).
I have used Amazon S3 for scalable and reliable data storage. This includes storing various types of data, such as static website assets, backup files, and multimedia content.
Data Management: I have configured S3 buckets, set up versioning, implemented lifecycle policies, and utilized event notifications to automate data management tasks.

Security: I have applied bucket policies, IAM (Identity and Access Management) roles, and S3 ACLs (Access Control Lists) to control access to S3 resources securely.

Data Transfer: I've managed data transfer in and out of S3, including using multipart uploads for large files and integrating S3 with other AWS services for seamless data processing.
11. Node.js. Please describe in detail your experience with Node.js
Backend Development: I have used Node.js extensively for backend web development. I've built server-side applications and RESTful APIs using frameworks like Express.js. This includes creating routes, handling HTTP requests and responses, and integrating with databases. I've worked with callbacks, Promises, and async/await to manage asynchronous operations efficiently, preventing blocking of the event loop. I'm proficient in using npm (Node Package Manager) to manage dependencies, install third-party libraries, and package my own modules for reuse across projects.I've connected Node.js applications to various databases, including relational databases like MySQL and PostgreSQL, as well as NoSQL databases like MongoDB. I've used libraries such as Mongoose and Sequelize for ORM (Object-Relational Mapping).I've implemented user authentication and authorization systems using libraries like Passport.js and JWT (JSON Web Tokens) to secure APIs and web applications.I've developed custom middleware functions to handle tasks such as logging, error handling, and request validation, enhancing the modularity and maintainability of applications. I'm experienced in deploying Node.js applications to various platforms, including AWS, Heroku, and VPS servers, and I've configured Nginx or other web servers as reverse proxies.I've used tools like Node.js's built-in debugging features, as well as external tools like New Relic and PM2, for monitoring and debugging Node.js applications in production. I'm proficient in using Git for version control, collaborating with teams on codebases, and managing code repositories.
