You will get a custom AI-powered Chrome browser extension
Project details
The best browser extensions feel like a superpower bolted onto the web, summarize this page, rewrite this text, pull this data, automate this task - right where the user already is. That's what I build.
I create custom Chrome extensions with AI built in: a one-click summarizer, an in-page writing assistant, a data extractor, a research copilot, a workflow automator. Whatever your idea, I build the extension, the page interactions, and the AI feature, and publish it to the Chrome Web Store.
Need more than a solo tool? I build the full thing — user accounts, saved settings, payments, a backend, even a dashboard — and ship it cross-browser to Chrome, Edge, and Firefox.
I'm full-stack and JavaScript-native, so the extension, the AI, and any backend all come from one engineer, not stitched together from three.
Want to see it work first? Start with the Extension Prototype — I build the core feature in 4 days so you can try it in your own browser before committing.
Tell me what the extension should do and I'll tell you how to build it.

Job Success
Devendranagar, India - 7:20 am local time
What makes this different: I combine full-stack engineering (Next.js, React Native, FastAPI, PostgreSQL) with deep AI integration (LangGraph, CrewAI, GPT, Claude, Gemini, Pinecone) in a single hire. No agency handoffs, no standups between a frontend dev and an AI specialist, one engineer who owns the whole stack. AI tools like Cursor and Claude Code are in my workflow from day one, which means tighter code and more delivered per dollar.
-----
Here's what I build:
- AI-Powered SaaS Platforms — LLM features built in from the first commit, not bolted on later
- Agentic Workflows & RAG Systems — multi-agent pipelines, document Q&A, enterprise search, internal copilots
- Voice & Chat Agents — real-time, multimodal, with persistent memory and tool use (Whisper, ElevenLabs, Twilio)
- Web & Mobile Apps — Next.js 15, React Native + Expo, iOS & Android, App Store ready
- Automation & Scraping Pipelines — n8n, Make, Playwright, Puppeteer; JS-rendered pages, anti-bot bypass
- API & Third-Party Integrations — Stripe, Twilio, WhatsApp Business API, HubSpot, CRMs
- SaaS & E-commerce — multi-tenant platforms, Shopify custom builds, marketplace and booking systems
- AI on Existing Products — add intelligence to what you already have without a full rewrite

If you have a product to build or an AI layer to add, send me a message, I typically respond within a few hours and can usually scope your project in a single conversation.
Steps for completing your project
After purchasing the project, send requirements so Saurabh can start the project.
Delivery time starts when Saurabh receives requirements from you.
Saurabh works on your project following the steps below.
Revisions may occur after the delivery date.
Scope the extension
We agree what the extension does, which pages it runs on, the trigger, and the AI feature, then I map it to Chrome's extension APIs.
Build the core
I build the extension — the UI, the page interactions, and the AI feature — and wire it to your chosen model and any backend it needs.
