Building intelligent software with
RAG • LLMs • Full Stack Engineering
I'm Yash Rai — an AI Product Engineer building production-ready SaaS applications with React, TypeScript, Node.js, Generative AI, Docker, and CI/CD. Creator of ResumeAI4U.
AI & LLM Integration
Production experience with OpenAI, Gemini, Claude & Groq Llama-3 API for sub-second inference.
Full-Stack Architecture
Type-safe React frontends connected to Node.js/Express REST APIs and Supabase/PostgreSQL databases.
DevOps & Cloud Ready
Configured GitHub Actions CI/CD pipelines, Docker containers, and automated Vercel deployments.
Production AI Case Studies
Real applications built with engineering rigor, AI integration, and production infrastructure.
ResumeAI4U (Flagship SaaS)
AI-Powered ATS Resume Analyzer & Optimizer
The Challenge
Problem:80% of resumes are filtered out by ATS parsers before reaching a human recruiter due to missing keywords and formatting errors.
Solution:An instant AI analysis engine that parses resumes against target job descriptions, delivering ATS match scores, keyword gap analysis, and line-by-line optimization.
Engineering & Architecture
- Groq API / LLM backend for sub-second inference latency over standard GPT-4.
- Clerk authentication + Razorpay billing pipeline integration.
- React + Node.js REST API architecture hosted on Vercel with automated CI/CD.
AI Study Assistant (RAG Platform)
Interactive Study & PDF Knowledge Base Powered by RAG
The Challenge
Problem:Students struggle to digest long academic PDFs and lecture notes efficiently, spending hours skimming 200+ page documents.
Solution:An AI study companion that turns notes into an interactive learning environment with semantic search, instant QA, auto-flashcards, and quizzes.
Engineering & Architecture
- RAG Pipeline: Vector embeddings with FAISS/ChromaDB + Gemini/Groq LLM for grounded contextual responses with citation support.
- Supabase storage for document management & structured user metadata.
- Express + Node.js backend handling document parsing, chunking, and vector indexing.

// 03 — Why Me
Why work with Yash
Ships Real Products
Not just localhost demos. I build and deploy products real people use — with auth, payments, and production infrastructure.
AI-First Approach
I integrate AI where it matters — from RAG pipelines to intelligent document analysis. Not buzzwords, real implementations.
Full Stack Capability
From Figma-quality frontends to scalable APIs and databases. One developer, complete product delivery.
Fast & Communicative
24-hour response time. Rapid prototyping with modern tools. You'll never wonder about project status.
Engineering Journey & Milestones
College Enrollment & Foundations
Enrolled in BCA at United Institute of Management, FUGS (Prayagraj). Started programming with C, Python, HTML, CSS & JavaScript.
Full Stack & Generative AI Engineering
Deep-dived into React, Node.js, Express & REST APIs. Explored LLM integration (OpenAI, Gemini, Claude, Groq API), RAG architectures & prompt engineering. Earned certifications from Oracle, IBM & Microsoft.
Production SaaS & Live Products
Shipped flagship ATS resume analyzer ResumeAI4U (live with Clerk auth & Razorpay) and AI Study Assistant (live RAG platform at ai-study-assistant-0.vercel.app). Implemented Docker & GitHub Actions CI/CD pipelines.
