💬 Potential Interview Questions

What are the advantages of using TypeScript over JavaScript in a full-stack application?
TypeScript offers static typing, better tooling support, and improved code maintainability, reducing bugs and improving developer productivity.
How would you structure a full-stack application using Node.js, React, and Postgres?
Backend with Node.js/Express handles API logic and database interaction, frontend in React manages UI and state, and Postgres serves as the relational database, all deployed via AWS services.
Describe your experience deploying Node.js applications to AWS.
I've used services like Lambda for serverless functions, EC2 for hosted services, RDS for Postgres, and S3/CloudFront for static assets, leveraging IAM roles for security.
How do you manage asynchronous operations in Node.js?
I use async/await and Promises to handle non-blocking I/O, and tools like SQS or background workers for task queues when needed.
What is your approach to error handling in a Node.js/Express API?
Centralized error middleware, structured error classes, and consistent logging ensure that errors are caught, logged, and responded to with appropriate HTTP status codes.
What techniques do you use for state management in React applications?
For local state, I use hooks like useState and useReducer; for global state, I use Context API or libraries like Redux or Zustand depending on complexity.
How do you ensure performance and scalability in a Postgres-backed application?
Indexing, query optimization, connection pooling, and monitoring tools like pg_stat_statements or AWS RDS Insights help maintain performance at scale.
What’s your experience with AWS services like Lambda, RDS, and SQS?
I've deployed serverless functions using Lambda, managed relational data with RDS (Postgres), and implemented event-driven architectures using SQS for decoupling components.
How would you implement user authentication in a React/Node.js app?
I’d use JWT for stateless auth, bcrypt for password hashing, and middleware to protect API routes, with frontend token handling via HTTP-only cookies or local storage.
Can you describe a time when you built something from scratch and how you approached it?
I designed and launched a full-stack web platform from initial wireframes, setting up the backend API, designing the schema, building the frontend UI, and deploying on AWS with CI/CD pipelines.
