Rachit Kumar Tiwari — AI, Full-Stack, Computer Vision

Building AI-native products with Next.js, TypeScript, Python and OpenCV

Computer Science Undergraduate · MAKAUT · Kolkata, India

Portfolio Resume LinkedIn Email

Open to SWE, AI and full-stack internships in 2026

About

I build AI-powered full-stack applications that solve real problems. My work spans generative AI (LLMs, RAG, agents), computer vision (OCR, OpenCV), and modern web stacks (Next.js, TypeScript, FastAPI).

What I care about in a codebase: explicit over clever, working over perfect, and edge cases caught before they ship.

Tech Stack

Languages

Python, TypeScript, JavaScript, Java, C, HTML, CSS

Frameworks & AI

Next.js, React, Tailwind, Node.js, Express, FastAPI, TensorFlow, OpenCV

Data & Tooling

MongoDB, Firebase, Supabase, Git, GitHub, Vercel, Linux, VS Code

Also working with: Gemini API, OpenAI API, retrieval-augmented generation, Pytesseract, WebSockets, and prompt engineering.

Featured Projects

Vocalis OS — Agentic AI Voice Assistant

Voice-first assistant with real-time speech recognition, LLM reasoning, tool calling, and persistent memory.

Next.js TypeScript Express.js Gemini API WebSockets Deepgram ElevenLabs

  • Agentic orchestration layer where the LLM selects tools (web search, calendar, tasks) from natural language rather than fixed intents
  • Streaming audio pipeline with conversational memory across turns and a modular plugin interface for new tools

Repository · Live Demo

Vitamend — AI Medicine Donation Platform

OCR and AI pipeline that automates medicine verification for donors and NGOs, cutting manual review out of the donation flow.

Next.js TypeScript MongoDB FastAPI OpenCV Pytesseract Gemini API

  • Verification pipeline chains OCR extraction, LLM validation, expiry checks, and QR confirmation into a single pass
  • Built both sides: computer vision service in Python and the React frontend against a MongoDB schema

Live Demo · Repository

Kred.ai — AI News Verification

Claim analysis grounded in live web evidence instead of model recall.

Next.js TypeScript Gemini API Serper API Tailwind CSS

  • Retrieval-augmented generation over live search results, so every verdict cites retrieved sources rather than asserting from parameters
  • Multilingual input with confidence scoring and structured citation output
