Question 1

How do you ensure AI applications don't hallucinate?

Accepted Answer

I enforce context boundaries using Retrieval-Augmented Generation (RAG), strict system prompts, and output validation layers that reject unauthorized responses.

Question 2

What LLM frameworks do you specialize in?

Accepted Answer

I specialize in Google Gemini (Flash & Pro), OpenAI models, LangChain agent orchestration, and Pinecone/Qdrant vector databases.

Question 3

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, ensuring near-zero latency.

Question 4

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 and Redis caching.

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, halving development timelines.

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

How do you handle cloud deployments?

Accepted Answer

I containerize applications with Docker and deploy them to cloud platforms like Vercel or AWS with automated CI/CD pipelines via GitHub Actions.

Question 8

Which backend framework do you recommend?

Accepted Answer

I recommend Node.js/Express for asynchronous real-time APIs and Python/FastAPI for data-heavy or AI-integrated services.

Question 9

What tool do you use for End-to-End browser testing?

Accepted Answer

I use Playwright because it supports chromium, firefox, and webkit engines natively with reliable auto-waiting and headless execution.

Question 10

Can dashboards handle live data updates?

Accepted Answer

Yes, I integrate WebSockets and Server-Sent Events (SSE) so metric charts update live without manual page reloads.

Question 11

What is the difference between a simple chatbot and an AI agent?

Accepted Answer

A simple chatbot follows rule-based responses, whereas an AI agent uses LLMs to reason, plan, select external tools, execute code, and make decisions autonomously to complete complex user requests.
