Hi! I'm Shubham Agrahari

Full Stack Engineer building agentic AI products with Next.js

Based in Pune, India. I ship TypeScript products end-to-end — React and Next.js 16 frontends, NestJS APIs and PostgreSQL data layers — and build GenAI features with the OpenAI SDK, Vercel AI SDK and RAG pipelines on pgvector.

Introduction

About me

I'm a Full Stack Engineer with 3+ years of TypeScript, React and Next.js experience, currently at Coditas Technologies in Pune. I started out building enterprise React and compliance products, and now focus on GenAI-powered, agentic applications — LLM integration, RAG pipelines on pgvector, and multi-step synthesis flows that orchestrate ingestion, signal extraction and automated reporting. I'm comfortable owning a feature from database schema to production UI.

Off the clock: badminton (intermediate, working on it), gym, running, swimming, solo trips, and way too many hours on Naruto, Demon Slayer, HIMYM, Big Bang Theory and Suits — fueled by coffee and biryani.

What I offer

What I do

Four areas I work in day to day — from GenAI features to the APIs and component libraries underneath them.

LLM-powered features with the OpenAI SDK and Vercel AI SDK — retrieval pipelines on pgvector, multi-step agents, and automated report generation.

Full-Stack React & Next.js

React 19 and Next.js 16 App Router products end-to-end: server-side data fetching, Prisma/Neon Postgres data layers, and Vercel deployments.

Frontend Architecture

Reusable component libraries, design systems, RBAC-driven UX, and data visualisation for enterprise SaaS — tested with Jest and RTL.

Backend & APIs

NestJS and Express REST APIs, event-driven notification systems, cron-based automation, and PostgreSQL schema design.
