You will get an AI feature added to your existing app or SaaS
Project details
You already have a product. What you don't have is the AI feature your users keep asking for, and bolting one on badly is worse than not having it.
I add AI to apps that already exist, without a rewrite. A copilot inside your dashboard, smart search across your users' content, auto-summaries, recommendations, built into your real UI and backend so it feels native, not like a chatbot taped to the corner.
This is the difference that matters: I'm a full-stack engineer, not just an AI layer. I work inside your existing codebase (Next.js, React Native, FastAPI, Postgres, whatever you run), wire the AI into your real data, and ship it to production.
It's also built right: proper prompts, retrieval where it helps, and guardrails so it doesn't hallucinate in front of your users.
Not sure how it'll work in your product? Start with the AI Feature Proof, I build a working version of your core feature in 3 days so you see it live before committing to the full thing.
Tell me what your product does and the feature you want, and I'll tell you how to build it in.

Job Success
Devendranagar, India - 6:39 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 feature
We agree exactly what the AI feature does, where it lives in your app, and what success looks like, then I map it to your stack.
Wire up the AI
I build the AI pipeline — prompts, retrieval if needed, and guardrails — and connect it to your data and chosen model.
