Question 1

Why do you use Next.js for web development?

Accepted Answer

Next.js offers superior server-side rendering (SSR), static site generation (SSG), and incremental static regeneration (ISR) out-of-the-box. This ensures search engines index content instantly and users experience near-zero latency.

Question 2

Can you build custom REST and GraphQL APIs?

Accepted Answer

Yes, I architect scalable backend microservices using Node.js/Express and Python/FastAPI with JWT authentication, secure databases, and high-performance caching via Redis.

Question 3

How do you ensure AI chatbots don't hallucinate or leak data?

Accepted Answer

I enforce context boundaries using Retrieval-Augmented Generation (RAG), strict prompt engineering instructions, and security validation layers that reject unauthorized requests.

Question 4

What AI models do you have experience working with?

Accepted Answer

I have extensive experience with Google Gemini (Flash/Pro), OpenAI GPT models, and tool orchestration using LangChain.

Question 5

Why choose React Native and Expo over native Swift or Kotlin?

Accepted Answer

React Native and Expo allow us to deploy to both Apple App Store and Google Play Store simultaneously from a single codebase. This halves development timelines and simplifies updates.

Question 6

Do your mobile apps support offline functionality?

Accepted Answer

Yes, I design apps with local database persistence and caching mechanisms so users can access core features offline.

Question 7

What is your testing approach for web applications?

Accepted Answer

I run unit/integration tests (Jest/Vitest) to check business logic, and end-to-end browser automation (Playwright) to verify user journeys across Chromium, WebKit, and Firefox.

Question 8

How do you automate deployments?

Accepted Answer

I write GitHub Actions workflows that automatically run linting, type-checks, and testing on pull requests, then build and deploy Docker containers to hosting environments.
