Selected Works
A collection of projects exploring the intersection of AI, real-time systems, and seamless user experiences.
Engineered an AI career co-pilot using Next.js 15 and Groq LLM to parse PDFs and generate structured resume-to-job match evaluations.
Integrated jSearch RapidAPI for live job matching and utilized Firebase Firestore via serverless APIs to persist user analysis history.
Engineered a real-time speech translation application leveraging Groq's Whisper API to transcribe and translate Hindi audio to English text.
Implemented robust asynchronous API handling using FormData and MediaRecorder API to capture high-quality audio streams.
Built a collaborative productivity platform using Next.js and TypeScript, enabling real-time task synchronization across multiple user workspaces.
Integrated a secure authentication system and Firebase Firestore backend to manage complex data relations and scalable user assignments.
Engineered a full Retrieval-Augmented Generation (RAG) system enabling users to upload PDFs and query private documents with grounded responses.
Built a FastAPI backend for document ingestion, text extraction, chunking, and persistent vector storage using ChromaDB.
Built a scalable Node.js and TypeScript REST API utilizing clean architecture and factory patterns to decouple business logic from LLM providers.
Implemented production-grade SaaS features including API key authentication, rate limiting, and usage tracking.
