Work Experience

Java Full Stack Developer Intern (AI/RAG Focus)

Infosys Springboard

Nov 2025 - Jan 2026 Remote
  • Shipped REST API integrations with Spring Boot + PostgreSQL; built frontend dashboards consuming LLM-powered endpoints with structured JSON contracts, enabling zero regressions to production.
  • Integrated LangChain RAG pipeline (FastAPI, pgvector, Claude API) with chunking, embedding, and reranking; reduced semantic search latency by 40% — used AI-assisted development responsibly with manual eval and quality-scoring tests.
  • Added JWT/OAuth2 authentication flows and WebSocket real-time notifications; debugged cross-browser rendering issues and applied accessibility improvements.

Full Stack Developer Intern

CertifyO

May 2025 - Jul 2025 Remote
  • Built and owned React.js frontend end-to-end — converted Figma mockups into responsive, production-quality interfaces and integrated 20+ RESTful API endpoints; handled full feature cycle from component design to deployment.
  • Scaled a React.js + WebSocket real-time platform to 500+ concurrent sessions at 99.8% uptime; applied performance optimisation (lazy loading, code splitting) to improve load times by 40%.
  • Implemented Redis caching and Node.js + MongoDB backend, achieving 60% API latency reduction — maintained clean, reusable component architecture throughout.

Projects

CodeQuest AI — AI-Powered Learning Dashboard

Next.js 14TypeScriptTailwind CSSshadcn/uiClaude API
  • Built a full-stack Next.js 14 + TypeScript application with Tailwind CSS + shadcn/ui component library; deployed on Vercel with CI/CD pipeline — converted complex UI designs into responsive, accessible interfaces.
  • Integrated Claude API tool calling for AI-driven code generation and inline feedback; used React Query for server-state management and structured JSON outputs for deterministic AI grading, cutting incorrect evaluations by 30%.
  • Leveraged Cursor and GitHub Copilot throughout development — validated all AI-generated code against eval datasets before merging; maintained clean component architecture with strong separation of concerns.

Vera Bot — Conversational Agent with React Frontend

ReactFastAPILangChainRAGPython
  • Designed and built the React frontend (chat UI, confidence indicators, citation display) consuming a FastAPI backend; integrated REST API with structured JSON responses for grounded, policy-safe answers.
  • Implemented RAG pipeline (retrieval→grounded answers→citations) with guardrails and fallback logic for low-certainty answers; submitted to magicpin AI Challenge.
