Prologue

Rajika Patel

I build and ship AI products that real people use — voice platforms, campus assistants, personal AI tools. If you're working on something with AI, I'd love to hear about it.

Chapter I

Building AI products,
start to finish

I'm an AI Developer & Product Builder at Jaipuria Institute of Management, where I design and ship LLM-powered products — Rehearsal AI, JChat, and life.ai among them. Most of my days go into turning ideas into tools that students and faculty can genuinely use.

I try to stay involved end to end. On one side, the AI itself — Claude and GPT, RAG, and voice. On the other, the product, the analytics, and the DevOps I manage to keep each release tested, secure, and running. I'm still learning plenty as I go, and I'm always happy to talk through anything AI-related.

A few things
I've built

i.

Rehearsal AI — Voice-Based Mock Interviews

A voice-based mock interview platform built on Next.js, Claude, and ElevenLabs, with real-time AI feedback on how you actually performed. 3,000+ students use it, and PostHog analytics across the product guide what gets built next.

life.ai — AI Personal Work Assistant

A personal AI assistant that helps you manage tasks, workflows, and the small frictions of a working day through plain conversation. Building it as a standalone web product, full experience designed end to end.

AI/LLM Conversational AI Web App

iii.

Highlyt — Context-Aware Reading Tool

A reading tool that keeps the intent behind every highlight — colour-coded meaning and your own connections between ideas, instead of flattening everything to plain text. It's built around the moment you decide something matters. Live at highlyt.app.

A white-labelled AI assistant for Jaipuria Institute that draws on multiple LLMs to answer students and faculty in context. Built, launched, and live for the whole campus.

Gita GPT — A GPT From Scratch

A GPT model built layer by layer — ~12 million parameters trained on a custom Bhagavad Gita dataset, ~97% accuracy. The project that taught me what's actually under the hood of every LLM I now build with.
